Man, I swear you're a life saver.. right now I'm 17 and buying my first car ('05 rx8) and even though I'm a car guy, I don't know that much about rotaries so thank you for helping us all.
Me:*uses exact same oil as previous owner to be safe* Video:*tells me I’m using the best oil for car and I now know the last owner wasn’t lying about taking care of it* Me:”nice”
The RX8 user manual recommends 5w-20 SL or ILSAC GF-3 oil, or mazda motor oil synthe-renesis 0w-30 according to the manual it is normal for it to consume oil and that is why it should be checked frequently and the oil should be changed every 5000 km or 3000 miles
In the UK, I've used Triple QX 10w40 and Millers Trident 10w40 based on recommendations from the owners club. Also Castrol Syntrans Multivehicle 75W-90 GL4 in the gearbox and Fuchs Titan Race Syn 5 75W90 GL5 in the rear diff. Lastly, Castrol Power 1 Racing 2T as pre-mix. All the above are recommended in the oil 101 thread on the owners club and are readily available on eBay etc. Hope this helps somebody looking to change all their fluids.
My goal is to buy strip down from top to bottom everything from the car and restore everything to make it like a brand new car. Your videos help me to some extent keep up the good work my man!
Awesome! I'm very happy you like it man :D That project will pay up really good in the future, as Rx8's in pristine condition will become quite expensive. So take very good care of it, and for re-sale value keep it stock!
Mineral Oils are called "Conventional" here in the States, for those wondering. Great vid as per usual ;) I have been using 5w20 all year round on my RX-8 for about 2.5 years. Mostly because I don't put on a lot of miles, so I'd have trouble switching oil viscosity per season here... I might actually consider 10w40 though... MPG will go down from what I hear :/
Same here. Been using 5w30 for the same amount of time as you did. I'm gonna switch to 10w30/10w40 in the next months before summer starts. Ohh well. i gave up on good mileage on this car, so it makes no difference to me :P Although having a Sohn adapter really makes a difference, and gives you more freedom as far as oils are concerned.
Hey madness. My 2 cents here on the oil viscosity I have experienced after 3 years. My car: 2009 RX8 R3 That's a series 2 engine with 3 oil injectors vs the series 1 with only 2 injectors. Little info of where I live: summer time temps can reach 115F and cool as 65F. Winter temps can drop as low as -20F and as warm as 60F. Bare in mind that 115 and -20 are extreme situations that occur only once every 2 or 3 years but can last for a few weeks at a time on occasions. Typically summer highs are 105F and winter lows are -5. In summer I first started with 5w-20 as stated in the owner book. I consumed approximately 1 quart every 1200 miles. Good consumption rate, poor lubrication though. Went to 5w-30 which yeilded a consumption rate of approximately 1 quart every 1800 miles again acceptable consumption and gave moderate amount of lubrication. Startups were uneffected, high rpm runs were smoother but a hair more sluggish from the thicker oil. Stepped up to 10w-30 and oil consumption went to 1 quart every 2000miles. the startups took one extra turn over so 3 turn overs instead of 2 which isn't a big deal still less than 5 seconds. High rpm wasnt changed from the 5w-30. Tried to step up again to 10w-40 which gave an oil consumption of 1 quart every 4500 miles. That's right it cut consumption to less than half. Again unchanged on start up from previous step but high rpm was noticeably bogged down to the point I was worried I had lost compression. My injectors were starving getting nearly no oil into the engine. Winter time: The results were nearly the same except back one step for each result... 10w-30 was the start of starving the engine even though it wasn't as bad it still took approximately 3300 miles to use 1 quart. In summary if you have weather similar to either of my patterns I would suggest 10w-30 for the hot times and 5w-30 for the cold times. I change my oils weight after the first solid 2 weeks of weather change.
Thanks for the feedback! those are some interesting stats there. Makes sense that the thinner oil gets pumped more, than the thicker one. Of course you have to also take into account driving habits, but i presume you kept the same rpm style are you did with the thinner oils. I also had subscribers write to me that their car is very sluggish from using thicker oils like 15w40 or 10w40 in really cold winters, where they've shoud have been using 5w30. I can't say more because i don't have any first hand experience with thicker oils. I'll switch to the 10w30 in the next months before summer starts. At the end of the season i'll be able to give some feedback about it. But since i have a sohn adapter i don't run the risk of starving the oil injectors, as they inject light 2 stroke oil, which is perfect. I guess one of the rotary experts might be able to give a better reply from their experience. Cheers!
Driven by madness I redline alot... Many times per drive. Always the same habit.. I DD the car to work an hour every week so it's the same drive and driving habits. I have series 2 so sohn adapter isn't an option for me sadly or I would have it installed already
Thank you very much for spreading the love for these absolutely beautiful cars !! I watch every episode you have done time and time again . Driven by madness is the pinnacle of RX8 VIDEOS!!
any quality synthetic oil will do. You can choose any thickness mentioned in the chart. it is preffered to have 10w40 or 10w50 for better protection when cold and hot.
I've been using valvoline 5w30 conventional for the 2 years I've owned my rx8 without issues. I change my oil every 3k miles and I also premix at every fill up. I may make the jump to 10w30 or 40 at the next oil change.
Hey guys I am new and also was wanting to get some feedback to see if royal purple is ok to use on rotarys I heard its excellent since its mineral based oil.
Thanks for the great video Driven by madness,your my inspiration bro,just bought my Rx8 and after watching all your videos I now know alot more about the engine and what upgrades and oil to use on it ect,thanks alot bro!!
Hi bro i purchased a pentrite 10W30 mineral oil. Do you think thats a good choice? Cause the guys at the shop said synthetic is no good for rotary. Also what do you think about using engine oil flush before draining the old oil? Do you recommend that? Thank you!
I honestly wish there was a Kit like the Sohn Adaptor for the Series 2 RX8s '09 - '11, because the only real options you have is premixing. I'd love to be able to run synthetic with a 2 cycle oil. I'm honestly surprised no one has come up with anything for that model year group.
Regarding the famous rotary engine tuner "RE Amemiya", the "RE" part is pronounced as 2 English letters "R" and "E" instead of "re", because they stand for "Rotary Engine"; and the leading "i" of "Idenmitsu" is pronounced as "e" not "i" because it's Japanese. Just my 2 cents.
I am the original owner of a 2004 RX8 MT. I've used 5W-20 Castrol Syntec for the life of the car. Never had problems. Still starts fine. No symptoms of low compression or bad bearings. Needs new mounts and a front oil seal though.
Hey men great videos and super helpful, but in your experience what do you think about using in a 07 rx8 Liqui Moly 15W40 for a hot climate Thanks in advance for any response
IT will work fine. Just remember, in winter 15w40 can get a bit too think, unless your winters are bearly under 0°C., in that case you can go all year long. But remember, without the sohn adapter, it's the engine lubricating system who pays the price if you go too think, easpecially in winter. The thicker, the slower the lubrication :) Hot climate and 15w40 = Super
Driven By Madness Driven By Madness hey men. Super awesome that you reply my comment. Thanks for the info and I love your channel, so yeah I live in Panama City, panama. (Central America) so there’s no winter, it’s hot summer all year long like 28 to 32 Celsius and very humid weather So I then I can stay with 15W40 and in the near future I will install the sohn adapter
What are your thoughts on Royal Purple synthetic oil? If it's a good fit for the rx8, Would that need a sohn adapter as well, or anything else special or could I just throw it in?
Wow, an oil thread that didn't degrade into flamethrowing, hate posts, threats, and, .PDF's from: SAE, & ASTM. Heck, it almost made sense too. Chris- the meds are working!!!! Thanks again, U da RX-8 MAN! Always worth the wait, even if it is a boring oil post. The post metro pressed and fitted shirt is just a little too gay, but- it looks good on you.
Give it time, it's just the first day. All the Rx8 guru's are still working. We'll see some serious shit going down once the weekend starts ;) No problem my happy formal clothes wearing fella. I just hope you wear a suit at the top and only underpants with high white socks at the bottom. That way people will know you mean business. resist 1 more month of informational vieos, and with april my drift build starts again. I'm not thrilled either, but some things are good to know and come in handy. Thanks! I like that shirt, it goes well with my underpants ;)
Tis the season for infomercials- agreed! Too cold- even in your sweet new garage home- this time of year. Well, let the games begin! Flame retardant undies- good call!!!
By the way, you should also do a video on how to change the oil in the RX8. Whole oil system flush as the some of the oil might be in the oil cooler :)
Without SOHN adapter (or without full premix) use mineral oil only. With SOHN adapter (or with full premix) you can use full synthetic oil in the oil pan (Mobil1 0w-30 or 0w-40)
I got my RX-8 since new (12 years now). I have 91.000 km in the first factory motor. 231 HP version. I drove in the last 36.000 km with Sohn adapter (Fuchs Titan 2T 100S for it's reservoir and for premixin as well) and M1 0w-30 for winter and M1 0w-40 for the summer. ;) After 20.000 km I looked in the oil pan and searched for metal particles. There was not a single one in it. This spring I will switch to Idemitsu premix for premixing and for the reservoir of the Sohn adapter.
Is there anything special that you need to do when changing from mineral to synthetic? pretty sure my engine has never had synthetic in it (bought used)
I live in curacao an island where the temperature is about 30 grad celsius . I am using valvoline 20w 50 high mileage , i just bought my rx8 3 months ago . When i do the service should i change the type of oil ?
Nice vid! Racing Beat, one of the biggest rotary builders in the world, give the thumbs up to Royal Purple for engines both with and without OMP. I have been running it for five years with no issues.
I recently bought about 4qt of lucas oil 10w40 semi synthetic but I am planning to switch over to Idemitsu. My question is would it be safe to use lucas oil until I change over to Idemitsu?
if my recommended is 10w20 and I decide to use 15w40, would I need a sohn adapter or would I be okay without one? In other words, will my oil injectors starve from 15w40 without sohn adapter, or is that only for the thicker oils.
having a sohn adapter is a insane advantage, as you are not restricted by any oil and you inject clean 2 stroke to burn & lubricate seals. 15w40 is a good choice if you race a lot and live in a relatively hot climate. Since it's a bit thicker it wont injected as good as lets say 10w30 or 10w40 but it will get injected. If it's winter then i wouldn't use it. using 20w50 without sohn adapter will starve your oil injectors. So if you're not planning on installing a sohn adapter and want to play it safe, stay 10w30 idemitsu or 10w40 :)
If you live in antartica that would be acceptable, but in any other place, that is too low. The only reason it was written that low is to lower emissions. 10w30 or 10w40 should be the standard
legit question on the Sohn adapter. I was told by a rotary specialist that the sohn is not reliable because its gravity fed. Is there any truth to this or alternatives? I premix every fill.
Should I get an RX8 it fits all my criteria apart from how much money I would have to spend on it as well as time. If not what other cars can I get similar to it, I was looking at BRZ but back seats are not that useable
If you have the money get a BRZ/GT86. RWD, good fuel economy, you dont' really buy a sports car for the rear seats, so you have to get used to it. The rx8 will cost less, but consume more fuel, at least 2x as much. So it's up to you and what kind of a budget you are ready to spend. (rx8 maintenence is super easy, and not that expensive)
Ciao, se ciai il shon, allora come oglio principare per il resto del motore netti pure 10w40 o 10w50. 5w30 seppur scorre prima, è troppo sottile, specialmente il w30 quando il motore è bello caldo. Con 10w40 vai sul sicuro, anche sintetico, ora che ha il shon. Nel shon ovviamente metti oglio a 2 tatti.
i use 10w 40 royal purple in my engine with shon adapter and use 2T royal purple for shon. I use too royal purple for syncro and differencial. it's wrong?. when i have to change oil? 5000km? twice in a year? or maybe 10000 for to use shon adapter?
Change oil every 3000 miles, no matter what you have installed. If that means twice/ year do it twice, if its 3 times, do it 3 times. I personally don't have any experience with royal purple, so i can't say why they didn't like it. If it worked till now, i guess stick with it, since you have a Sohn. I use Idemitsu Premix, redline transmission oil and will upgrade to the idemitsu 10w30 oil in the next months.
hey just bought an rx8 for 2.5k not the best price but in my area its 5k lower than the next car. One problem apex seals. How much to replace them and can the replace by myslef. Ty
Welcome to the club :) Apex seal replacement ranges from 1800 to 2800€. it's best to let a professional rotary mechanic do it, as you have to dismantle the whole engine and inspect it for wear. Once you know the level of wear, you have an idea of what needs to be replaced and what can be reused. On a side note, some people prefer to buy a rebuilt engine and swap it with the current one. Cheaper & faster. cost around 1000€ - 1500€
I have done last October my Big Oilchange at 113830Km and changed to the Idemitsu 10w30 Racing Oil and an K&N HP1008 Oilfilter since ive changed, it Runs much better, even the cooling and Compression the startings too. Thats what i expirienced. The Sohn Adapter will Surely come too. Do you have a Link km Your Sohn Adapter install video where to get the Plates, Cans Pipes and the sohn adapter in one kit itself?
My mates are running synthetic oil with no issue, dang oil is like religion in the rotary community, or gambling I can say. My first mate is running RX8 turbo with OMP, same with second one but without turbo, both 10W-40. Yeah mineral oil is for the safe side, but synthetics.... Thanks for the tips!
The running with no issues part is covered in the Q&A, if you're interested in the answer from rotary shops. If not injected to burn, synthetics are far far superior to mineral and semi synthetic ones. That's why i've installed a sohn adapter, and enjoy the freedom of oil :) No problem man, i'm glad you like them !
Yeah, Sohn Adapter is one of the most useful mods for the car. I'm rocking with mineral oil lmao it's cheaper as well. I still wonder how some people switch to synthetics with OMP with no issue (so far, around 7 years).
I'm not sure what you read, but basically, the purpose of the Sohn Adapter is to feed 2-stroke oil into the engine via the OMP. The OMP feeds regular 4-stroke oil from your oil pan into the engine combustion chamber. That's how Mazda designed it, but there are some flaws, as that oil that is being injected is usually dirty or just the sheer fact that 2-stroke burns better than 4-stroke. The reason the Sohn Adapter may not be a perfect solution to the Apex seal lubrication, is because it still operates based on the OMP. So it injects the 2-stroke oil only when the OMP is doing its job, which is above 4k-4.5k RPM. So you are still starving the apex seals of oil below that RPM. The reason we premix 2-stroke with our gas, is so that there is oil to lubricate the Apex seals at all RPM ranges. Don't get me wrong, the Sohn Adapter is a great thing, definitely better than leaving the car stock as it is, but it still does not address the issue fully. If you want, you can go ahead and get it installed, but I would consider premixing instead, or along with, the Sohn Adapter. Just keep in mind, that if you have the Sohn Adapter installed, you will have to premix less. For example: without the Sohn Adapter, I premix 1oz of 2-stroke per 1 gallon of gas for my daily driving. With the Sohn Adapter installed, you would probably only need to premix 0.5 oz per 1 gallon of gas, if you choose to go this route. People can feel free to correct me on what I stated above, but as far as me and my RX-8, I'm just premixing 1oz of 2-stroke per 1 gal of gas, no Sohn Adapter.
How do you know that 10w30 is better? There are none proves to it, why do you think that it will be better then 5w30? Yeah yeah - thicker oil it still does not mean that wear will be less or that it will not have other downsides.
@@danimal7913 Already found something else, but thanks, btw Dexelia is Total 5w30 Classic, cause Total makes the oil for Mazda. And with a hot summer temperatures rounding 40° C that is too much stress for such thin oil.
Hey man. Having some major issues out of my Rx8. When I'm driving and put it in neutral it turns off. Changed the spark plugs but not the wires nor coils. Could that be my issue??
Dwayne Jr Try changing your wires and coils as well. It might be that your coils are shot and if that's the case might as well change the wires while you're at it. Also try checking your battery and alternator. If those are good, check your MAF sensor and Eccentric shaft position sensor. Clean them off as well as any other semsors and connections and that might help. Look for any leaks in the intake system. Usually found around the accordion tubing on your intake as well as the three vaccuum hoses connected to it. Finally check your air filter and throttle body. Sometimes the filter is gunked up or throttle body is stuck. A lot of people had your same issue, including myself, and checking all of those things usually helped solve the problem. If you've done all of those things and still have issues while idling try getting a compression test to see how the engine is working. Hopefully that baby is healthy and it's just the little things that are preventing it from staying on. Best of luck!
Call me crazy, but first you mention that thicker oil than mazda's recommended 5w30 is better for the engine. Then, in the chart under "Best recommended oil" it says 10w30.... I'm confused.
i don't have experience with it. Most american oils people use are not sold here in europe. But for better protection i would switch to 10w30 idemitsu. There's a link in the description if you want to check it out :)
amsoil is by some the best other saying idemitsu..there is also here some engines with and without amsoil but it might be advertising..mildrens.com.au/articles/best-oil-for-your-mazda-rx8/ yes its hard to find in europe..but i can find it about at 11 euros..i live in greece..compare to the very expensive idemitsu essex rotary are very good but prices are 10 years back..when the rx8 cost about 40.000 euros..iam an owner from then... keep the good work..
I appreciate the video, however the information in this one isn't on point. Having gotten to know a mechanic that builds rotary engines for customers all over the world and working with Mazda and Ianetti, I've learned that the best oil, if your environment doesn't get over 50 degrees Celsius, is penrite 5W30 mineral oil. You should never run a synthetic oil that has not been specially designed for rotary engines and these oils are not commonly available. The reason you shouldn't use synthetic is actually because that inside engine are some soft rubber seals and control rings that actually get eroded by petroleum based compounds, which are what most of these are made of. If you have a SOHN adapter, you should be running a thin mineral oil in the engine that won't boil, such as 5W30, and a high performance 2 stroke oil in the external reservoir for the SOHN adapter such as the Mobil 1 gold racing 2T or the Motul 800 2T. These are what are recommended for use after hundreds of hours of race testing, so if you want a street car that will always perform, use 5W30 in the sump, get a SOHN adapter and use a high performance 2 stroke oil for the combustion chamber. And if you never want your engine to die, combine this with Ianetti ceramic apex seals.
Do you use conventional/mineral oil or synthetic? For conventional, oil changes should happen every 2,500 - 3,000 miles (whatever that is in KM, a few less than 5,000) no questions asked. The oil can get very dirty very quickly in some RX-8s, and pumping that stuff into the combustion chamber via the OMP when the RPM goes up there, is probably not a great idea. Not to mention other factors that could be causing harm if the oil sits in the engine for too many miles. For Synthetic, I'm assuming it would be 5,000 miles, but I don't know, I don't use synthetic.
If thicker is better, and considering a Sohn adapter is in place, I would prefer the Motul sport 5w-50. Most of the bearing's wear out occurs during start up, and while the engine is still cold, that's why you would need the lower "5w" value so that the oil can start flowing asap when cranking the engine and as the engine heats up. And the thicker side "50" would be of benefit when the engine has reached the operating temperature.
That was also my first choice,, as i have used mobil 1 peak 5w50 on my previous car. Sadly i can't tell you more than what i said in the video. I'll try and ask the 2 rotary shops to give a more accurate explanation about it. Cheers!
I've asked them and here's the answer: Engine doesn’t flow ASAP. There is a thermal pellet that doesn’t allow flow until warm. Replace it with aftermarket and it fixes that.
What I mentioned has to do with the bearings. Oil WILL flow to the bearings but not to the rotors when motor is cold. Due to insufficient oil flow to the bearings on cold temperatures engines need to be rebuilt due to bearings failure. Check the following Link from Atkins Rotary for reference. www.atkinsrotary.com/store/86-11-Rx7-and-Rx8-Atkins-Thermal-Pellet-ARE50.html
His mistake, you are correct the oil flow to the bearings. 50w would benefit operating temperature. 5w and 10w start flowing at the same time but 5w get there a fraction of a second before 10w, but will be too thin until the car warms up. On the other side, thicker oils 10w stick to bearings for a longer period, thus reducing dry start damage and providing better protection while warming up. 5w woud be far better off in colder weathers, where its viscosity would be optimal. Dry starts are very short on rx8's engine, they are more of an issue in piston engines, cause oil takes more time to reach. eshafts and bearings last over 100k miles. This is what i got :)
I just bought my 1st RX8. 2009 Grand Touring with the MT and 73K Miles. 2nd Gen with an Oil Cap that says 5W-20 and 100% Synthetic according to the Mazda Owner's Manual. Then I start reading and before I know it the History of the Rotary and Rev Rotary and all the other SMEs leads me to certain conclusions. 1. I personally have NO intentions of installing a Sohn Adapter after removing the Oil Metering Pump which happens to be connected to the 6 Oil Injector Nozzles (4 for the Gen 1 Engines). Why? I don't consider myself smarter than the Mazda Wankel engine Engineering Team. However, I do completely agree that 100% Synthetic Oil is BAD for a Rotary Engine simply because it doesn't BURN very well and we need a Hydrocarbon to BURN Clean after doing it's primary job of lubricating the Apex and Side Seals. Semi Synthetic Oils in America are 50% Conventional and 50% Synthetic. 10W-40 Semi Synthetic High Mileage Valvoliine. Castrol. or any other Brand meeting our API Specs should work fine according to the Experts over at Rev Rotary, RAD, and Yourself according to your chart. I fully intend to keep my '09 RX8 GT MT in an OEM Stock Condition. No Racing Planned. No Drifting Planned. Just spirited Sports Car Driving in America. Mazda, as well as all the other Manufacturers, have been told that 5W20 is the NEW Gold Standard for Energy Efficiency and Lubrication in almost ALL of our automotive ICEs. Really? I was shopping at Walmart 2 days ago and ALL of the Engine Oil was 5W-20. Seriously. You have to either order the Semi Synthetic/Blended 10W-40 Online, or find it at some of the Chain Parts Stores like AutoZone or NAPA or O'Rileys. I honestly think that given the Oil Consumption rate and OEM OMP Systems working fine that the 10W40 Semi Synthetic will work fine here in NW Florida. Regularly Checking and Changing the Oil and Filter is just as critical in every aspect. Of course I'm just the FNG so what do I know. Great Video....Job Well Done and a sincere Thank You from America. JP

Hey madness. My 2 cents here on the oil viscosity I have experienced after 3 years.
My car: 2009 RX8 R3
That's a series 2 engine with 3 oil injectors vs the series 1 with only 2 injectors.
Little info of where I live: summer time temps can reach 115F and cool as 65F.
Winter temps can drop as low as -20F and as warm as 60F.
Bare in mind that 115 and -20 are extreme situations that occur only once every 2 or 3 years but can last for a few weeks at a time on occasions. Typically summer highs are 105F and winter lows are -5.
In summer I first started with 5w-20 as stated in the owner book. I consumed approximately 1 quart every 1200 miles. Good consumption rate, poor lubrication though.
Went to 5w-30 which yeilded a consumption rate of approximately 1 quart every 1800 miles again acceptable consumption and gave moderate amount of lubrication. Startups were uneffected, high rpm runs were smoother but a hair more sluggish from the thicker oil.
Stepped up to 10w-30 and oil consumption went to 1 quart every 2000miles. the startups took one extra turn over so 3 turn overs instead of 2 which isn't a big deal still less than 5 seconds. High rpm wasnt changed from the 5w-30.
Tried to step up again to 10w-40 which gave an oil consumption of 1 quart every 4500 miles. That's right it cut consumption to less than half. Again unchanged on start up from previous step but high rpm was noticeably bogged down to the point I was worried I had lost compression. My injectors were starving getting nearly no oil into the engine.
Winter time:
The results were nearly the same except back one step for each result... 10w-30 was the start of starving the engine even though it wasn't as bad it still took approximately 3300 miles to use 1 quart.
In summary if you have weather similar to either of my patterns I would suggest 10w-30 for the hot times and 5w-30 for the cold times. I change my oils weight after the first solid 2 weeks of weather change.
Thanks for the feedback! those are some interesting stats there. Makes sense that the thinner oil gets pumped more, than the thicker one. Of course you have to also take into account driving habits, but i presume you kept the same rpm style are you did with the thinner oils.
I also had subscribers write to me that their car is very sluggish from using thicker oils like 15w40 or 10w40 in really cold winters, where they've shoud have been using 5w30.
I can't say more because i don't have any first hand experience with thicker oils. I'll switch to the 10w30 in the next months before summer starts. At the end of the season i'll be able to give some feedback about it.
But since i have a sohn adapter i don't run the risk of starving the oil injectors, as they inject light 2 stroke oil, which is perfect.
I guess one of the rotary experts might be able to give a better reply from their experience.
Cheers!
Driven by madness I redline alot... Many times per drive. Always the same habit.. I DD the car to work an hour every week so it's the same drive and driving habits.
I have series 2 so sohn adapter isn't an option for me sadly or I would have it installed already
Thank you very much for spreading the love for these absolutely beautiful cars !! I watch every episode you have done time and time again . Driven by madness is the pinnacle of RX8 VIDEOS!!
*⚡Thinking of installing a sohn adapter? Here's my how to video that will make the install FAST & EASY! **ua-cam.com/video/sNYOmLX3jAQ/v-deo.html** ⚡*
When you have the Sohn adapter installed, is there a preferred synthetic oil?
any quality synthetic oil will do. You can choose any thickness mentioned in the chart. it is preffered to have 10w40 or 10w50 for better protection when cold and hot.
I have a 2007. That is similar design to the 09+ where I dont need a sohn correct?
If I could, I’d give you ten thumbs up! Great job mate, thank you!
I've been using valvoline 5w30 conventional for the 2 years I've owned my rx8 without issues. I change my oil every 3k miles and I also premix at every fill up. I may make the jump to 10w30 or 40 at the next oil change.
Rx8mauri_ same here bro! Conveniently my oil schedule is due in the next months, so I can rock summer with a new fresh 10w30 oil 👌
Hey guys I am new and also was wanting to get some feedback to see if royal purple is ok to use on rotarys I heard its excellent since its mineral based oil.
thinking about using the idemitsu mentioned in the video
Oliver szabó awesome! im also gonna use the idemitsu for my oil change next month. Gotta start this drift season with fresh oil 👌😊
since it always summer in Suriname (Latin-America), the general oil used is 10w40... cause there are just two seasons ..rain and summer
Thanks for the great video Driven by madness,your my inspiration bro,just bought my Rx8 and after watching all your videos I now know alot more about the engine and what upgrades and oil to use on it ect,thanks alot bro!!
Love your videos man!!! Big thanks. My Rex is so much better now after your first mods video! Big love
i agree with this. thats why im using a havoline 10w 40... my rx8 havnt have any problems at all
jonathan palacio still good lol?
El mejor es 20w50 en verano en PR y en temperaturas ambiente 10w40 castrol , valvoline y idemitsu
Hello! In a hot climate which oil is recommended for whole year instead of 5w30 which is recommended by Mazda?
Hi bro i purchased a pentrite 10W30 mineral oil. Do you think thats a good choice? Cause the guys at the shop said synthetic is no good for rotary. Also what do you think about using engine oil flush before draining the old oil? Do you recommend that? Thank you!
I honestly wish there was a Kit like the Sohn Adaptor for the Series 2 RX8s '09 - '11, because the only real options you have is premixing. I'd love to be able to run synthetic with a 2 cycle oil. I'm honestly surprised no one has come up with anything for that model year group.
Please make a video about RX8 hard power steering issue, there is no video DIY cleaning connectors etc..
Thanks from France ! ;)
Regarding the famous rotary engine tuner "RE Amemiya", the "RE" part is pronounced as 2 English letters "R" and "E" instead of "re", because they stand for "Rotary Engine"; and the leading "i" of "Idenmitsu" is pronounced as "e" not "i" because it's Japanese. Just my 2 cents.
I can’t premix now because I still have stock exhaust system? If I don’t but add this is it ok? Does it get enough oil as the oil pan?
Hey Madness, what do you recommend for both engine oil and sohn/premix oil after an engine rebuild (bearings and seals)? And how to break-in?
I am the original owner of a 2004 RX8 MT. I've used 5W-20 Castrol Syntec for the life of the car. Never had problems. Still starts fine. No symptoms of low compression or bad bearings. Needs new mounts and a front oil seal though.
I use twenty weight conventional mineral. You can thank syntec for your leak. I use my brothers used rotella fourty weight.
How's the engine 5 years later?
@@ve2430Still runs well. But showing its age. When it gets heat-soaked it doesn't have much power.
Hey men great videos and super helpful, but in your experience what do you think about using in a 07 rx8 Liqui Moly 15W40 for a hot climate
Thanks in advance for any response
IT will work fine. Just remember, in winter 15w40 can get a bit too think, unless your winters are bearly under 0°C., in that case you can go all year long. But remember, without the sohn adapter, it's the engine lubricating system who pays the price if you go too think, easpecially in winter.
The thicker, the slower the lubrication :)
Hot climate and 15w40 = Super
Driven By Madness Driven By Madness hey men. Super awesome that you reply my comment.
Thanks for the info and I love your channel, so yeah I live in Panama City, panama. (Central America) so there’s no winter, it’s hot summer all year long like 28 to 32 Celsius and very humid weather
So I then I can stay with 15W40 and in the near future I will install the sohn adapter
What are your thoughts on Royal Purple synthetic oil? If it's a good fit for the rx8, Would that need a sohn adapter as well, or anything else special or could I just throw it in?
Wow, an oil thread that didn't degrade into flamethrowing, hate posts, threats, and, .PDF's from: SAE, & ASTM. Heck, it almost made sense too. Chris- the meds are working!!!! Thanks again, U da RX-8 MAN! Always worth the wait, even if it is a boring oil post. The post metro pressed and fitted shirt is just a little too gay, but- it looks good on you.
Give it time, it's just the first day. All the Rx8 guru's are still working. We'll see some serious shit going down once the weekend starts ;) No problem my happy formal clothes wearing fella. I just hope you wear a suit at the top and only underpants with high white socks at the bottom. That way people will know you mean business. resist 1 more month of informational vieos, and with april my drift build starts again. I'm not thrilled either, but some things are good to know and come in handy. Thanks! I like that shirt, it goes well with my underpants ;)
Tis the season for infomercials- agreed! Too cold- even in your sweet new garage home- this time of year. Well, let the games begin! Flame retardant undies- good call!!!
Thanks for you videos am in the usa,I appreciate it.
Thanks man, glad to hear that.
By the way, you should also do a video on how to change the oil in the RX8. Whole oil system flush as the some of the oil might be in the oil cooler :)
That's what i have planned in the coming month. I need to go from 5w30 to 10w30 so i'll do a complete oil change/flush :)
Really helpful video - thanks for sharing!
Without SOHN adapter (or without full premix) use mineral oil only.
With SOHN adapter (or with full premix) you can use full synthetic oil in the oil pan (Mobil1 0w-30 or 0w-40)
I agree, but 0w is far too low and will offer very little protection for bearings. (as i understood)
I got my RX-8 since new (12 years now). I have 91.000 km in the first factory motor. 231 HP version. I drove in the last 36.000 km with Sohn adapter (Fuchs Titan 2T 100S for it's reservoir and for premixin as well) and M1 0w-30 for winter and M1 0w-40 for the summer. ;) After 20.000 km I looked in the oil pan and searched for metal particles. There was not a single one in it. This spring I will switch to Idemitsu premix for premixing and for the reservoir of the Sohn adapter.
Is there anything special that you need to do when changing from mineral to synthetic? pretty sure my engine has never had synthetic in it (bought used)
I live in curacao an island where the temperature is about 30 grad celsius . I am using valvoline 20w 50 high mileage , i just bought my rx8 3 months ago . When i do the service should i change the type of oil ?
Nice vid! Racing Beat, one of the biggest rotary builders in the world, give the thumbs up to Royal Purple for engines both with and without OMP. I have been running it for five years with no issues.
Thanks! Well, i have no first hand experience with it, so i can't say why they consider it not good.
Great video man, hope your videos get more views
Thanks!
Thanks for the heart
@@gabrielcalhoun9060 thanks for the kind motivational comment 😊
I recently bought about 4qt of lucas oil 10w40 semi synthetic but I am planning to switch over to Idemitsu. My question is would it be safe to use lucas oil until I change over to Idemitsu?
Can I use fully sinthetic oil that's not specifically used for rotaries?
Is 10w-30 Castrol a good choice?
.,its winter here and i need to change oil., whichshould i go for idemitsu 15w40 or 10w40?
if my recommended is 10w20 and I decide to use 15w40, would I need a sohn adapter or would I be okay without one? In other words, will my oil injectors starve from 15w40 without sohn adapter, or is that only for the thicker oils.
having a sohn adapter is a insane advantage, as you are not restricted by any oil and you inject clean 2 stroke to burn & lubricate seals. 15w40 is a good choice if you race a lot and live in a relatively hot climate. Since it's a bit thicker it wont injected as good as lets say 10w30 or 10w40 but it will get injected. If it's winter then i wouldn't use it. using 20w50 without sohn adapter will starve your oil injectors.
So if you're not planning on installing a sohn adapter and want to play it safe, stay 10w30 idemitsu or 10w40 :)
Go to Black Halo Racing WEB site. Have a WORLD of info. on the RX8 and what works!!!!!!
I was reading the manual because I just got an rx8, and the oil it likes is 5w-20
If you live in antartica that would be acceptable, but in any other place, that is too low. The only reason it was written that low is to lower emissions. 10w30 or 10w40 should be the standard
@@Drivenbymadness Want to move from 5w-30 dexelia as well,
Are you sure that 10w30 will be better? No idea how to check it
legit question on the Sohn adapter. I was told by a rotary specialist that the sohn is not reliable because its gravity fed. Is there any truth to this or alternatives? I premix every fill.
Driven by madness
will a coolant seal up product reduce the or seal ur broken RX8 cooland seal from smoking??
Should I get an RX8 it fits all my criteria apart from how much money I would have to spend on it as well as time. If not what other cars can I get similar to it, I was looking at BRZ but back seats are not that useable
GamingTuberTV the RX8 is very practical you won’t regret it!
mischiefpwns it's just the fuel economy and oil and time needed to maintain the car, that's why I was looking at alternatives. Any suggestions
If you have the money get a BRZ/GT86. RWD, good fuel economy, you dont' really buy a sports car for the rear seats, so you have to get used to it. The rx8 will cost less, but consume more fuel, at least 2x as much. So it's up to you and what kind of a budget you are ready to spend. (rx8 maintenence is super easy, and not that expensive)
Driven by madness ok thanks still looking into it, but what would you say is the best 2 things about the rx8
Ciao, io ho il kit sohn per la miscela, cosa ne pensi dell'olio 5W30 amsoil signature serie per lubrificare il resto del motore?
Ciao, se ciai il shon, allora come oglio principare per il resto del motore netti pure 10w40 o 10w50.
5w30 seppur scorre prima, è troppo sottile, specialmente il w30 quando il motore è bello caldo. Con 10w40 vai sul sicuro, anche sintetico, ora che ha il shon. Nel shon ovviamente metti oglio a 2 tatti.
I'm finding a Bizol 10w40 HC synthesis A3 b4...is this good oil for the Series 2 rx8?
Hi! What do you think about royal purple hps? Racing beat use it
Where do I find the oil adapter kit for a 2005 Mazda RX8
We use total quartz 9k in czech. Its dexelia in other bottle.
Yeah, i've heard that they are the same thing.
would any brand of 10w30 sytnhetic be ok? or it has to be idemitsu?
i use 10w 40 royal purple in my engine with shon adapter and use 2T royal purple for shon. I use too royal purple for syncro and differencial. it's wrong?. when i have to change oil? 5000km? twice in a year? or maybe 10000 for to use shon adapter?
Change oil every 3000 miles, no matter what you have installed. If that means twice/ year do it twice, if its 3 times, do it 3 times. I personally don't have any experience with royal purple, so i can't say why they didn't like it. If it worked till now, i guess stick with it, since you have a Sohn. I use Idemitsu Premix, redline transmission oil and will upgrade to the idemitsu 10w30 oil in the next months.
hey just bought an rx8 for 2.5k not the best price but in my area its 5k lower than the next car. One problem apex seals. How much to replace them and can the replace by myslef. Ty
Welcome to the club :) Apex seal replacement ranges from 1800 to 2800€. it's best to let a professional rotary mechanic do it, as you have to dismantle the whole engine and inspect it for wear. Once you know the level of wear, you have an idea of what needs to be replaced and what can be reused.
On a side note, some people prefer to buy a rebuilt engine and swap it with the current one. Cheaper & faster. cost around 1000€ - 1500€
I have done last October my Big Oilchange at 113830Km and changed to the Idemitsu 10w30 Racing Oil and an K&N HP1008 Oilfilter since ive changed, it Runs much better, even the cooling and Compression the startings too. Thats what i expirienced. The Sohn Adapter will Surely come too. Do you have a Link km Your Sohn Adapter install video where to get the Plates, Cans Pipes and the sohn adapter in one kit itself?
SilverShadowLP awesome! Im also considering the idenitsu 10w30. The sohn is a great mod. You can find the full kit in the description :)
Also the install video is on my channel :)
What is the recommend oil for Rx8 in Hong Kong? Temperature around 20-30 degree
10w40
Is this for 2009 rx8 also or just 04 to 08 mazda rx8.
What about mazda dexelia ultra 5w30? Does it fit rx-8 well?
My mates are running synthetic oil with no issue, dang oil is like religion in the rotary community, or gambling I can say.
My first mate is running RX8 turbo with OMP, same with second one but without turbo, both 10W-40.
Yeah mineral oil is for the safe side, but synthetics....
Thanks for the tips!
The running with no issues part is covered in the Q&A, if you're interested in the answer from rotary shops. If not injected to burn, synthetics are far far superior to mineral and semi synthetic ones. That's why i've installed a sohn adapter, and enjoy the freedom of oil :) No problem man, i'm glad you like them !
Yeah, Sohn Adapter is one of the most useful mods for the car. I'm rocking with mineral oil lmao it's cheaper as well.
I still wonder how some people switch to synthetics with OMP with no issue (so far, around 7 years).
Hi
I read on rx8club that the sohn adapter prevents certain parts of the engine from receiving lubrication
I'm not sure what you read, but basically, the purpose of the Sohn Adapter is to feed 2-stroke oil into the engine via the OMP. The OMP feeds regular 4-stroke oil from your oil pan into the engine combustion chamber. That's how Mazda designed it, but there are some flaws, as that oil that is being injected is usually dirty or just the sheer fact that 2-stroke burns better than 4-stroke. The reason the Sohn Adapter may not be a perfect solution to the Apex seal lubrication, is because it still operates based on the OMP. So it injects the 2-stroke oil only when the OMP is doing its job, which is above 4k-4.5k RPM. So you are still starving the apex seals of oil below that RPM. The reason we premix 2-stroke with our gas, is so that there is oil to lubricate the Apex seals at all RPM ranges. Don't get me wrong, the Sohn Adapter is a great thing, definitely better than leaving the car stock as it is, but it still does not address the issue fully. If you want, you can go ahead and get it installed, but I would consider premixing instead, or along with, the Sohn Adapter. Just keep in mind, that if you have the Sohn Adapter installed, you will have to premix less. For example: without the Sohn Adapter, I premix 1oz of 2-stroke per 1 gallon of gas for my daily driving. With the Sohn Adapter installed, you would probably only need to premix 0.5 oz per 1 gallon of gas, if you choose to go this route. People can feel free to correct me on what I stated above, but as far as me and my RX-8, I'm just premixing 1oz of 2-stroke per 1 gal of gas, no Sohn Adapter.
nonsense, it simply changes where the OMP gets its oil from.
From watching the sohn adapter install video, it seems like the OMP still gets oil from the crankcase, but it combines it w/ 2-stroke oil...?
Like I said, I am open to being corrected...
How do you know that 10w30 is better?
There are none proves to it, why do you think that it will be better then 5w30?
Yeah yeah - thicker oil it still does not mean that wear will be less or that it will not have other downsides.
Should I replace my oil filter every time I change my oil?
yes
next month when i change my oil i'll go for a thicker grade than the 5w-20 i've run over the winter (cold af winters, hot af summers)
You can run thicker oils in summer and less thicker in winter. That's a good combo. 10w30 is a great all around oil.
So a Castrol GTX Ultraclean 10w40 A3/B4 would work just as good as idemitsu ?
Yes
No, just go to your Mazda dealer, they will recommend Mazda Motor oil Ultra Dexelka 5W30. 5 litre will cost you around 55 euro. Dont buy Castrol.
@@danimal7913 Already found something else, but thanks, btw Dexelia is Total 5w30 Classic, cause Total makes the oil for Mazda. And with a hot summer temperatures rounding 40° C that is too much stress for such thin oil.

Do you need sohn adapter to use this engine oil? My car is 2009 Model
Sohn adapter is only if you want to use full synthetic or use a heavier oil
But if you have the S2 rx8, there isnt an sohn for your model
@@Drivenbymadness ahhh I see.. so I can just use idemitsu engine oil straight away right?
Hey man. Having some major issues out of my Rx8. When I'm driving and put it in neutral it turns off. Changed the spark plugs but not the wires nor coils. Could that be my issue??
Dwayne Jr Try changing your wires and coils as well. It might be that your coils are shot and if that's the case might as well change the wires while you're at it. Also try checking your battery and alternator. If those are good, check your MAF sensor and Eccentric shaft position sensor. Clean them off as well as any other semsors and connections and that might help. Look for any leaks in the intake system. Usually found around the accordion tubing on your intake as well as the three vaccuum hoses connected to it. Finally check your air filter and throttle body. Sometimes the filter is gunked up or throttle body is stuck. A lot of people had your same issue, including myself, and checking all of those things usually helped solve the problem. If you've done all of those things and still have issues while idling try getting a compression test to see how the engine is working. Hopefully that baby is healthy and it's just the little things that are preventing it from staying on. Best of luck!
Jairo Umana thanks man! I really appreciate it
Dwayne Jr
No problem!
Has anyone looked into the possibility of using TC-W3 outboard 2 stoke instead of motor oil?
will you ever think about porting your rx8's engine?
Perhaps when i rebuild it, but i'll decide once they give me a quote for how much it would all cost.
Call me crazy, but first you mention that thicker oil than mazda's recommended 5w30 is better for the engine. Then, in the chart under "Best recommended oil" it says 10w30....
I'm confused.
Mazda's reccomended is 5w30. Rotary experts reccomend 10w30 :)
That still means that under operating temperature, there is no difference between the two..
ask essex rotary or t-rex for specifics. I can only tell you as much as i have said in the video :/
What's your opinion about amsoil 5-30?
i don't have experience with it. Most american oils people use are not sold here in europe. But for better protection i would switch to 10w30 idemitsu. There's a link in the description if you want to check it out :)
amsoil is by some the best other saying idemitsu..there is also here some engines with and without amsoil but it might be advertising..mildrens.com.au/articles/best-oil-for-your-mazda-rx8/
yes its hard to find in europe..but i can find it about at 11 euros..i live in greece..compare to the very expensive idemitsu
essex rotary are very good but prices are 10 years back..when the rx8 cost about 40.000 euros..iam an owner from then...
keep the good work..
I’m using 5w 20.. and the weather fluctuates between -3 & -17 😂 what do you recommend
Is that celsius?
Is valvoline 10w20 ok to use
10w30 or above 10w40
I appreciate the video, however the information in this one isn't on point. Having gotten to know a mechanic that builds rotary engines for customers all over the world and working with Mazda and Ianetti, I've learned that the best oil, if your environment doesn't get over 50 degrees Celsius, is penrite 5W30 mineral oil. You should never run a synthetic oil that has not been specially designed for rotary engines and these oils are not commonly available. The reason you shouldn't use synthetic is actually because that inside engine are some soft rubber seals and control rings that actually get eroded by petroleum based compounds, which are what most of these are made of. If you have a SOHN adapter, you should be running a thin mineral oil in the engine that won't boil, such as 5W30, and a high performance 2 stroke oil in the external reservoir for the SOHN adapter such as the Mobil 1 gold racing 2T or the Motul 800 2T. These are what are recommended for use after hundreds of hours of race testing, so if you want a street car that will always perform, use 5W30 in the sump, get a SOHN adapter and use a high performance 2 stroke oil for the combustion chamber. And if you never want your engine to die, combine this with Ianetti ceramic apex seals.
use all ois xs nanno
Every 5,000KM? My maintenance schedule (Schedule 2 for Canada) calls for changes every 8,000KM.
Do you use conventional/mineral oil or synthetic? For conventional, oil changes should happen every 2,500 - 3,000 miles (whatever that is in KM, a few less than 5,000) no questions asked. The oil can get very dirty very quickly in some RX-8s, and pumping that stuff into the combustion chamber via the OMP when the RPM goes up there, is probably not a great idea. Not to mention other factors that could be causing harm if the oil sits in the engine for too many miles. For Synthetic, I'm assuming it would be 5,000 miles, but I don't know, I don't use synthetic.
5000 km is reccommended, 8000km is the maximum you should wait.
Go to Black Halo Racing!!!!!!!! Have a world of info. on RX8's also!!!! Idemitsu Racing Oil? Who carries it?
I use royal purple just cause I can get it locally
If thicker is better, and considering a Sohn adapter is in place, I would prefer the Motul sport 5w-50. Most of the bearing's wear out occurs during start up, and while the engine is still cold, that's why you would need the lower "5w" value so that the oil can start flowing asap when cranking the engine and as the engine heats up. And the thicker side "50" would be of benefit when the engine has reached the operating temperature.
That was also my first choice,, as i have used mobil 1 peak 5w50 on my previous car. Sadly i can't tell you more than what i said in the video. I'll try and ask the 2 rotary shops to give a more accurate explanation about it. Cheers!
I've asked them and here's the answer: Engine doesn’t flow ASAP. There is a thermal pellet that doesn’t allow flow until warm. Replace it with aftermarket and it fixes that.
What I mentioned has to do with the bearings. Oil WILL flow to the bearings but not to the rotors when motor is cold. Due to insufficient oil flow to the bearings on cold temperatures engines need to be rebuilt due to bearings failure. Check the following Link from Atkins Rotary for reference.
www.atkinsrotary.com/store/86-11-Rx7-and-Rx8-Atkins-Thermal-Pellet-ARE50.html
His mistake, you are correct the oil flow to the bearings. 50w would benefit operating temperature. 5w and 10w start flowing at the same time but 5w get there a fraction of a second before 10w, but will be too thin until the car warms up. On the other side, thicker oils 10w stick to bearings for a longer period, thus reducing dry start damage and providing better protection while warming up.
5w woud be far better off in colder weathers, where its viscosity would be optimal.
Dry starts are very short on rx8's engine, they are more of an issue in piston engines, cause oil takes more time to reach. eshafts and bearings last over 100k miles.
This is what i got :)

I just bought my 1st RX8. 2009 Grand Touring with the MT and 73K Miles. 2nd Gen with an Oil Cap that says 5W-20 and 100% Synthetic according to the Mazda Owner's Manual. Then I start reading and before I know it the History of the Rotary and Rev Rotary and all the other SMEs leads me to certain conclusions. 1. I personally have NO intentions of installing a Sohn Adapter after removing the Oil Metering Pump which happens to be connected to the 6 Oil Injector Nozzles (4 for the Gen 1 Engines). Why? I don't consider myself smarter than the Mazda Wankel engine Engineering Team. However, I do completely agree that 100% Synthetic Oil is BAD for a Rotary Engine simply because it doesn't BURN very well and we need a Hydrocarbon to BURN Clean after doing it's primary job of lubricating the Apex and Side Seals. Semi Synthetic Oils in America are 50% Conventional and 50% Synthetic. 10W-40 Semi Synthetic High Mileage Valvoliine. Castrol. or any other Brand meeting our API Specs should work fine according to the Experts over at Rev Rotary, RAD, and Yourself according to your chart. I fully intend to keep my '09 RX8 GT MT in an OEM Stock Condition. No Racing Planned. No Drifting Planned. Just spirited Sports Car Driving in America. Mazda, as well as all the other Manufacturers, have been told that 5W20 is the NEW Gold Standard for Energy Efficiency and Lubrication in almost ALL of our automotive ICEs. Really? I was shopping at Walmart 2 days ago and ALL of the Engine Oil was 5W-20. Seriously. You have to either order the Semi Synthetic/Blended 10W-40 Online, or find it at some of the Chain Parts Stores like AutoZone or NAPA or O'Rileys. I honestly think that given the Oil Consumption rate and OEM OMP Systems working fine that the 10W40 Semi Synthetic will work fine here in NW Florida. Regularly Checking and Changing the Oil and Filter is just as critical in every aspect. Of course I'm just the FNG so what do I know. Great Video....Job Well Done and a sincere Thank You from America. JP

I recently bought about 4qt of lucas oil 10w30 full synthetic but I am planning to switch over to Idemitsu. My question is would it be safe to use lucas oil until I change over to Idemitsu?
