You should make a list of things that need to be maintained on B58 2/3/440i's, and at what mileage/how long to go between service intervals. As a 340i owner, there is so much conflicting information about maintenance, having you break it down clearly would really help!
Service interval should be between 5K - 10K miles/1 year, whichever comes first. If you drive the piss out of it then 5K, if you driver normal around town then 7.5K, if you drive on the highway a lot then 10K. Do not go beyond 10K and also keep an eye on the oil temps and that will give you a good relative idea of how the oil could be performing. My N55 starts to burn oil between 6K and 8K, which is my cue to change it. The engine has 163K miles and it runs like it did when new.
@@AgonxOC Yup this right here. I follow the same rule, once I start burning oil or get a low oil level light which is usually about every 8-9k km I change the oil.
Before watching this, I had 100% convinced myself to move to a 0w-30 or 40 on the next change but what you say here makes perfect sense. My oil temp stays rock solid around 230 even during extended highway runs and the car has under 50k miles on it too, so definitely no reason to go up yet. Thanks as always for sharing your extensive knowledge of these cars.
Correction. The car was designed to run on 0w-20 to improve its fuel economy. Running the correct oil is always the better choice because running an oil is too thick can cause damage. You're welcome
@@kern417 If you look at the manual closely, it says 0W-40, 0W-30, 5W-40, 5W-30, 0W-20 or 5W-20. BMW recommend 30 or even 40 weight for cars sold in Europe, that should tell you something. 0W-20 is to meeting EPA fuel economy requirement but at the expense of engine wear.

Hallo. Ich fahre ein 340 mit 450ps. Seit. 4 Jahren und habe 80000km gefahren. Hier in Deutschland immer schnell unterwegs. 250+ .auch im Sommer keine Probleme. Habe 0w20 Titan EVO GT1. Wechsel das Öl alle 10000km. Der Motor ist für das Öl ausgelegt und ideal für das geringe Lagerspiel und Vanos Steuerung.
Motul in its catalog recommends 8100 5w40, in my city the ambient temperatures range between 0º and 40º in winter or summer, it must also be taken into account that my car is modified and it would be ideal to keep the oil pressure stable in conditions of maximum demand with a lot of heat.
The reason for 0-20 oils is because of all of the modern automobiles automatic transmissions keep the engine RPMs under 2k at all times when normal driving. Note this, its the key to all of the answers about 0-20 oils. Also all of the modern car engines have short and light pistons that can not be compared with anything that was made in 90s Understood you may race once or twice a week for a brief moment but most of the time your car spends under 2k RPM when normal driven. Why is this important? Because when you drive normally your transmission keeps the RPM low to reduce emissions and increase fuel economy but with it, the actual STRAIN AND PRESSURE on the piston is MUCH HIGHER than if you were spinning the engine at 3-4 k RPM while coasting down street. That increased pressure combined with already light and short piston height causes the piston to wear the cylinder walls faster than it would be on the older vehicles because the older engines had a much higher piston height and higher nominal RPMs. To combat that they had to reduce the spacing between the cylinder wall and the piston, to reduce the side movement of the piston. But because of it, they needed a much thinner oil. If you put a thicker oil in the engine, it will act best under stress but while normal driving, which I assume most do 90% of the time it will actually harm the engine. BMW Engineers arent stupid.

i put it also 1 Liter when it was warning me oil is in low, i piut 5w-30 bmw oil but someone says its 0w 20 good now im so xonfused what we should put?
great info. I actually made the switch from 0w-20 to 0w-30 Valvoline European bmw ll-01. I do some spirited driving twice a month, and burn less oil than when I was running 0w-20. Before I had to top off about .5-1qt every 2k or so. The most I had to top off was maybe half a quart at about 4k. 0w-30 and 0w-40 for the win all day!
Amsoil makes a wonderful "European Spec" 0W-20 and an even better Signature Series 0W-20. I probably wouldn't use sig series until after yanking the stock cat off like you did. Those European emissions/cats are no joke.
I was curious about this. I swapped from BMW oil to Amsoil Euro 0w20 as soon as I bought the car. I have since went catless with a stage 2 tune. I wasn't sure if it was ok to switch to Amsoil Signature 0w20 or maybe even 0w30 on my next oil change?
Weather is important, living in Florida are summers are very hot, I run 0-30 in my xDrive 440i, no issues, the slightly thicker oil helps combat overheating, heat thins oil and when it's already very hot it can get too thin at 0-20, all shops in hot climates suggest *-30 for summer, most of us running year-round.
Weather doesn't matter. Our cooling system works well whether it's 30F or 100+. And thick oil doesn't combat overheating. You need to improve your cooling system for that.
In Germany BMW Service fill 5W-30 LL04 in all M, N and B engines. DPF and OPF (you don't need this filter in US pollution laws, I've heard) need a low ash (SAPS) Oil. S engines gets different Oil
Very informative video. I had experienced some oil consumption, 0W20 full synthetic Pennzoil. I didnt get a warning or anything but i always check my oil. Thinking of making the switch to 0W40, its LL01 Approved. Is it normal for 0W20 to be burned in a stage 2 catless downpipe, 91 oct B58?
I love how this comment section is a b58 forum. Ive been running 0-20 on FBO and MHD tune i mainly daily except a few pulls to try and clean the carbon. I live in the country side but i did a few test cruising home at 55 and 65, normal temp a lil over 210°f but at 65 it drops down to like 190°f, has anyone noticed this with just 10mph?
Trying to pick the right Liqui Moly product. They recommend 0W-20 Top Tec 6600 but on FCP Euro they recommend 5W-30 because "New BMW's fitted with BXX series engines "Require" 0W-20 LL14FE+ Rated oils. WE DO NOT RECOMMEND using this spec! The levels of protection LL14FE provides are much lower than LL01. The new formulation LL14FE is mainly designed with CAFE ratings, EPA requirements and fuel mileage in mind, NOT OVERALL PROTECTION.""
It doesn't really matter what they say. The OEM designed the car to meet a standard and that includes everything i mentioned in the video. That being said, the LiquiMoly that I saw meets the LL01FE cert as well.
So after checking and learning from this the best answer is to keep using the factory recommended oil until you start tweaking the car then you go to a thicker oil ?
Even when making more power the factory oil is pretty good. Stick with oils that meet the oem cert in your manual and do an oil analysis when you can for peace of mind.
Thanks, kern417. I’ve got a lot of knowledge from your channel about basic technology and mod for B58. Recently I changed oil by myself. I chose ‘Liquimoly synthoil 5w-40’ than ‘Leichtlauf 5w-40’ ,because ‘synthoil’ is advertised as ‘fully synthetic’. But ‘Liquimoly synthoil’ is approved as ‘BMW long life 98’ , not ‘BMW long life 01or 04. Do you think it will cause any trouble? My 340i is tuned by MHD and xHP, catless downpipe, CSF heat exchanger, tuHPFP. MHD setting is ‘stage2 98ron, sport cooling mode’. Oil temp remain under 100°C under street use. I have two questions blow. ①Does ‘BMW long life98 approved oil’ cause an issue on B58? ②’MHD stock cooling mode’ keeps my oil temp around120℃ @10℃ ambient temp. ‘Sport cooling mode’ keeps it under 100℃. Which mode is better for street use?
Ight so I be pushing my car, and ofc not until oil is up to temp, and transmission over 170-180 °F. What oil do you recommend? Currently running 5W-30 which is what the previous has done every 4k miles.
Any loss in power or mpg for you with 0w40? I’ve got a stage 2 M140i manual. I’m switching to 0w40 and curious as I get 46mpg cruising in eco mode (very rarely use it, mainly sport/sport+) at 65-70mph.
@@a20axf Hi, I was also interested in finding out with running a thicker oil would affect performance so I did back to back runs using a draggy and the numbers were identical 30-70mph 3rd gear 3.8s.
@@a20axfYep B58 M140i ZF8. Only mod is a Remus race catback. It's only reving at 1500rpm at 64mph couple that with a torquey engine and it just sips fuel. It's actually better than my bros 2010 E250cdi doing the same test :-)
@@kern417 Thanks! Yeah I think so too. It’s for normal daily driving only, not a big deal which oil I use. But I really like Liqui Moly...good quality stuff.
Based on your video, im thinking 5w-30 on my stage 2.5/2+ 440i. Im in SoCal so it’s never reaches sub-freezing temps, and I dont beat on my car very much. I plan on running logs as well, but what do you think?
I live in Australia and summer is approaching it usually hovers around 35-40c for ambient temperatures in prime summer. We have an Australian branded oil called penrite built for Australian conditions. What would you say to be using 0w-30 or 5w-30 full synthetic with a gen1 b58 at 100k kms and running stage 2+ BM3 tune and downpipe with supra HPFP installed.
Would you advise using heavier weight for higher mileage? I own a 17’ 340ix and MTC records showed that when I bought it in 19’ it had been serviced with 5W-30 it now has over 60K and I never changed to 0W-20 because it had previously been serviced with higher weight and because I don’t know all the ins and outs of it I was afraid to change it. Live in central USA parks inside except 1-3 starts a month. Weather dips below freezing a few times a year but nothing extreme.
Kerns I currently bought redline euro 5w40. HTHS is at 4.3cP. would that be too thick for the b58b30o1? It's a 23' gr supra with 1500miles. Want to dump factory fill but I can't find and and oil, bearing, or valvetrain clearance specifications online. Even vanos
Hi, thanks for your content, I follow you even if I have a B48 engine. It isn't the subject of the video, but I would like to make a question to you. I own a 120i stage 2, tuned with MG Flasher. I can set the "Regular engine temperature" from the settings. You know the original temperature is around 230F (very high), what do you think is the best regular engine temperature for a tuned B48-B58? Thanks so much.
@@federoco1 With MG you can toggle it on the fly through the dome light button. The cooling mode is not really much use unless you are on a track, because all your doing is stressing the water pump more.
@@siornetwork7701 Yes, I know the cooling on the fly. Since the oem temperature is very high, some people (like me) set regular temperature near 90-95° celsius. So the engine is always "fresh" and performer, without press the dome light each time. Maybe I wrong, I don't know... Most cars have water temp. at 90°celsius permanent
Agree with what you say, but... If you read thru the various forum boards, guys who routinely analyze their oil get the best results with 0w40 or 5w40 ll-01 spec oil. Then there's the guys who really beat on their turbo engines that swear by rotella 15w40 T6, although it is not ll-01 certified. In the chart that you put up, an oil with a 3.5 High Shear Viscosity or better is where you want to be. Below 2.5 any you are asking for trouble. And remember that oil with miles on it breaks down over time, so you may loose a point after 5000 miles or so.
I'm not sure where you're getting your info but you absolutely should not run 15w40. Plenty of people get good data with 0w20 as well. Stick with what the engine is designed for and you'll have the best luck.
@@kern417 My info comes from the race/drift guys who beat on their oil pretty hard. And yes, the higher shear oils within a given viscosity do consistently exhibit less wear. This is a big reason why Amsoil, Penzoil, and Castroil synthetics generally do well when compared to the rest.
You can't just go to anyone to get info because they drift their cars. Do they have B58s? Stock engines? Whats their oil change frequency? What oil temps do they see? You're talking about something that doesn't relate to the topic at hand. Running that heavy of an oil on your B58 will ruin it. All you're doing is slowing down the oil's flow when it's cold, which is when the most wear happens. Do more research and you'll understand.
I run 0w-20 on my B46 X3. I live in Florida where it’s 90 degrees plus year round. I often see myself pushing the car to the limiter at around 4-4500rpm for no more than 15min at a time sustained on the express lane quite often, been that way since new (30k mi ago). I never run the car hard before turning it off (I don’t like the fans doing the cooling for me). I change oil every 4k mi. Car is stock other than for a dinan piggy back. Is there anything I should be doing to maximize engine life? I know these cars a designed for autobahn use and meant to sustain high speeds
How do you like your BMW with the B46. I just got one. I'm in Miami, Florida. I was surprised about the 0w20. Never had a car with such thin oil. The Deaker told me South Motors they recommend at 60 to 70k to put 0w30. I told they why not 0W30 from the beginning to prevent wear. They Saud I could ask the service dept. to put the thicker oil (0W30), or even 5W30, if I wanted, but the 0W30 flows better . Tgey also told me that the 0W20 provides better gas mileage, wich lead me to believe the thin oil was just for saving gas, but then I run into this video. I'm only at almost 500 miles, and I plan on doing the first change early before 1k, perhaps even a second early one as well, abd then do them 4 to 5 k from then on. Wgat type if oil brand a tree you using, and how do you like the X3, and B46 thus far ?
I'll try to touch on it in A future video, but look up "B58 vs B58TU." The primary difference is the M340i/Supra HPFP can support more power, and certain models have lower compression than the older engines.
It Should be fine. You can always send out an oil analysis during one of your future oil changes for peace of mind, but the engine will do what it's designed to.
I would like to use my b58 mainly in race track even for long periods of times like 2laps on nürburg ring, drift racing ect with mhd around 500hp. 0w-30 BMW oil going to be satisfying in you opinion?
So happy I found this channel! New B58 owner. Yes I bought used but from a friend. I now see that one 0w20 is fine even tuned but noticed a lot of you guys going 5w30. I’m looking at Liquid Molly and it gives those 2 options. Why are you all going 5w30 instead?
I think if you are in a climate where you don't drive your car in freezing temps then 5W-30 is fine. I also used 0w-20 then 5W40 and now 5W30 just because I like changing things and collecting data. But I wouldn't expect a noticeable difference in performance.
I’m in Florida, hot and humid here. I greatly appreciate your reply. I’m watching your videos like I have a text on Monday! Everyone told me not to buy a used BMW because they don’t last. So I want to do everything I can so that it does last! It’s a 2017 440i Grand Coupe with 41k mikes.
I put 5W-40 liqui molly in my engine and i swear the engine is slower after , its adding up now, is it true thicker oil is better for your engine long term?
@@kern417 hey did you ever get to try 5w30? if so how was it? i have a Gen1 340xi B58 running stage 2.0 up in CT where its cold most of the year. i have my eye on liqui molly 5W-30 but haven't decided which weigh to go with!
Hey man, just bought myself a 2019 540i, i'm looking to do my oil change and i was thinking of just doing mobil 1 0w20, but i wanted to ask what specific oil would i get? I'm trying to look for the spec on the mobil 1 0w20 fuel economy and extended performance variants but i don't see the bmw LL14-fe spec on any of them
Look for the spec on the front and the back. If it's not on the 0w-20 bottle then look at some of the other oil weights. They might have one under 0w30
Do you recommend using ceratec in the oil change ? I’m about to hit 50k idk if it’s necessary to coat the motor with it now but I’d want to do it for preventative
brother subbed. been watched your vids for over an hour. amazing content. so rare to find someone that actually knows what the fuck theyre talking about. I have an x3 m40i, 2018. as far as the motor/ turbo goes, are there any key differences compared to the 2/3/440i?
Nope it's pretty much the same, but fitment for some parts like the intake and heat exchanger will be different just because you have a bigger engine bay. But turbos, downpipes, etc that bolt to the engine should have the same fitment.
@@kern417 what if I tune my 340i? I plan on getting a catless downpipe and a stage 2 tune via mg flasher. Will 0w20 still be good for daily driving and some spirited driving?
Way way too thick. You want to use the thinnest oil you can while maintaining hot oil pressure within spec. Fluid is non compressible. The viscosity’s job is to provide adequate hot pressure. You’re losing power and getting excess heat from your motor having to churn through that thick oil. 540ratblog.wordpress.com
I subscribed to your channel. A lot of good information that helps a lot. I use Valvoline C2 0w30 LL-12 FE, with stage2+ E30 on my 18’ 340i in Eu. I am going to change to Liqui Moly with the same specs, or should I change to 0w40 or 5w30? I don’t know what will be the best for me on stage2+ E30?
Both will work. If you will be Starting your car in sub-freezing temps then the 0w will provide better cold start protection. But 5W works great as well.

Weather doesn't matter. Our cooling system works well whether it's 30F or 100+. And thick oil doesn't combat overheating. You need to improve your cooling system for that.
In Germany BMW Service fill 5W-30 LL04 in all M, N and B engines. DPF and OPF (you don't need this filter in US pollution laws, I've heard) need a low ash (SAPS) Oil. S engines gets different Oil
In Germany, is there a case of excessive oil consumption of B48TU and oil in the threads of No. 1 and No. 2 spark plugs?
i check my manual for the M340i, SAE 5W-30 can be used. BMW Longlife-04
In Germany Bmw dealer allways used 0w30 on my g30 540i
question is 0w20 was burning much faster , is it ?
I live in Florida and use Motul specific LL01FE
great videos brotha! thanks for the guidance to others man keep up the good work
My friend, great channel congratz. Do i use ll04 or ll01 in my 440i 2019?? it comes with the extra liter of ll04.....i am in EUR
Very informative video. I had experienced some oil consumption, 0W20 full synthetic Pennzoil. I didnt get a warning or anything but i always check my oil.
Thinking of making the switch to 0W40, its LL01 Approved.
Is it normal for 0W20 to be burned in a stage 2 catless downpipe, 91 oct B58?
Not in my experience but every car is different. I currently run 0w30
Thank you for the information very useful, nice turbo as well
I love how this comment section is a b58 forum. Ive been running 0-20 on FBO and MHD tune i mainly daily except a few pulls to try and clean the carbon. I live in the country side but i did a few test cruising home at 55 and 65, normal temp a lil over 210°f but at 65 it drops down to like 190°f, has anyone noticed this with just 10mph?
Do you have sport Cooling on?
I do actually that explains it

Just subscribed. Always great information. Thank you
Trying to pick the right Liqui Moly product. They recommend 0W-20 Top Tec 6600 but on FCP Euro they recommend 5W-30 because "New BMW's fitted with BXX series engines "Require" 0W-20 LL14FE+ Rated oils. WE DO NOT RECOMMEND using this spec! The levels of protection LL14FE provides are much lower than LL01. The new formulation LL14FE is mainly designed with CAFE ratings, EPA requirements and fuel mileage in mind, NOT OVERALL PROTECTION.""
It doesn't really matter what they say. The OEM designed the car to meet a standard and that includes everything i mentioned in the video. That being said, the LiquiMoly that I saw meets the LL01FE cert as well.
@@kern417 Good info thanks
Always informing the people, great in depth video brotha 🙌🏽
Thanks. Probably a lot More than most people care to know haha
So after checking and learning from this the best answer is to keep using the factory recommended oil until you start tweaking the car then you go to a thicker oil ?
Even when making more power the factory oil is pretty good. Stick with oils that meet the oem cert in your manual and do an oil analysis when you can for peace of mind.
Why not 0w40 ? Will be more stable at higher temperature
Thanks, kern417. I’ve got a lot of knowledge from your channel about basic technology and mod for B58.
Recently I changed oil by myself.
I chose ‘Liquimoly synthoil 5w-40’ than ‘Leichtlauf 5w-40’ ,because ‘synthoil’ is advertised as ‘fully synthetic’.
But ‘Liquimoly synthoil’ is approved as ‘BMW long life 98’ , not ‘BMW long life 01or 04.
Do you think it will cause any trouble?
My 340i is tuned by MHD and xHP, catless downpipe, CSF heat exchanger, tuHPFP.
MHD setting is ‘stage2 98ron, sport cooling mode’.
Oil temp remain under 100°C under street use.
I have two questions blow.
①Does ‘BMW long life98 approved oil’ cause an issue on B58?
②’MHD stock cooling mode’ keeps my oil temp around120℃ @10℃ ambient temp.
‘Sport cooling mode’ keeps it under 100℃.
Which mode is better for street use?
I would recommend switching to the LL01 oil at your next oil change
I don't use sport Cooling mode personally Because I don't see the need. My oil temps are controlled well without it on.
Thanks, I appreciate your advice.
Why wouldn’t you recommend LL98 if that is a true synthetic oil? Vs liquimoly high tech which is a blend but advertised as “full synthetic”
Just because it's a synthetic oil doesn't mean it's designed for your engine or meets the requirements. Watch the video.
Just an awesome informative video, well done 👏
Hi, this oil is for NA only, what is the equivalent for the EU market?
How do you feel about BMW's 0w20 "Twin Power Oil" that you can get at you local BMW dealership?
I feel like it works well for most setups
My owners manual for 2019 440i xdrive says 0W-20 or 0W-30
Excellent info.
Always informative 👍🏼👍🏼👍🏼
Ight so I be pushing my car, and ofc not until oil is up to temp, and transmission over 170-180 °F.
What oil do you recommend?
Currently running 5W-30 which is what the previous has done every 4k miles.
That's fine
@@kern417 thanks
Here in UK the manual also state's 30/40 viscosity oils can be used. I'm personally running Mobil 1 FS 0w40 as it was a good price.
Any loss in power or mpg for you with 0w40? I’ve got a stage 2 M140i manual. I’m switching to 0w40 and curious as I get 46mpg cruising in eco mode (very rarely use it, mainly sport/sport+) at 65-70mph.

I switched to 5w30 this year
BMW recommended 5 - 30 in our region "In the middle east"
Is this makes sense?
yes
Thank you.
Why is your turbo there ?
Is the Liqui Moly 5W40 ok in Texas? FCP Euro says it has better protection than the recommended 0w20.
It should be ok but 0w20 should be ok too
@@kern417 Thanks! Yeah I think so too. It’s for normal daily driving only, not a big deal which oil I use. But I really like Liqui Moly...good quality stuff.

Hi Sir, what engine oil you recommend for N20 Bm3 Stage 1, downpipe, NGK 97506 spark plug? Thanks.
B58 FTW
Based on your video, im thinking 5w-30 on my stage 2.5/2+ 440i. Im in SoCal so it’s never reaches sub-freezing temps, and I dont beat on my car very much. I plan on running logs as well, but what do you think?
Should be fine. Get an oil analysis to confirm
Great content, very informative thank you
I live in Australia and summer is approaching it usually hovers around 35-40c for ambient temperatures in prime summer. We have an Australian branded oil called penrite built for Australian conditions. What would you say to be using 0w-30 or 5w-30 full synthetic with a gen1 b58 at 100k kms and running stage 2+ BM3 tune and downpipe with supra HPFP installed.
Should be fine
would u recommend staying at 0W 20 im staying in AZ where it gets hot hella, 110, lowest we see i think is 40s
You could run 0w20 or 0w30
I live in Florida I would run 0w30
Would you advise using heavier weight for higher mileage? I own a 17’ 340ix and MTC records showed that when I bought it in 19’ it had been serviced with 5W-30 it now has over 60K and I never changed to 0W-20 because it had previously been serviced with higher weight and because I don’t know all the ins and outs of it I was afraid to change it. Live in central USA parks inside except 1-3 starts a month. Weather dips below freezing a few times a year but nothing extreme.
shouldn't make a difference
What is your thought about using CASTROL EDGE 0W-40 A3/B4 for this engine?
During winter time, would it be better using 0W-20 then 0W-40?
operating temp is the same in winter and summer, so either will work fine. i like 0w20 and 0w30.
So basically im stage 2 mhd and dp charge pipe i should just keep 0w-20, outside parking cold temps in winter (NY)
yep 0w20 or 0w30 would both work great
Full synthetic ?
how would you compare 5w40 vs 5w30? thanks
Hi Kern, i have a question pls, i wanna try the Penzzoil 0W-20 for my BMW 540i g30 b58, what do u think? Ur opinion maters.
If it meets the BMW spec it should be fine
Kerns I currently bought redline euro 5w40. HTHS is at 4.3cP. would that be too thick for the b58b30o1? It's a 23' gr supra with 1500miles. Want to dump factory fill but I can't find and and oil, bearing, or valvetrain clearance specifications online. Even vanos
It's probably fine. I ran 5w40 for 5000 miles no issue
Hi, thanks for your content, I follow you even if I have a B48 engine. It isn't the subject of the video, but I would like to make a question to you. I own a 120i stage 2, tuned with MG Flasher. I can set the "Regular engine temperature" from the settings. You know the original temperature is around 230F (very high), what do you think is the best regular engine temperature for a tuned B48-B58? Thanks so much.
It will maintain the same temps when tuned and should not be an issue.
@@kern417 So, would you keep oem setting, 230F?
@@federoco1 yes
@@federoco1 With MG you can toggle it on the fly through the dome light button. The cooling mode is not really much use unless you are on a track, because all your doing is stressing the water pump more.
@@siornetwork7701 Yes, I know the cooling on the fly. Since the oem temperature is very high, some people (like me) set regular temperature near 90-95° celsius. So the engine is always "fresh" and performer, without press the dome light each time. Maybe I wrong, I don't know... Most cars have water temp. at 90°celsius permanent
Agree with what you say, but...
If you read thru the various forum boards, guys who routinely analyze their oil get the best results with 0w40 or 5w40 ll-01 spec oil. Then there's the guys who really beat on their turbo engines that swear by rotella 15w40 T6, although it is not ll-01 certified. In the chart that you put up, an oil with a 3.5 High Shear Viscosity or better is where you want to be. Below 2.5 any you are asking for trouble. And remember that oil with miles on it breaks down over time, so you may loose a point after 5000 miles or so.
I'm not sure where you're getting your info but you absolutely should not run 15w40. Plenty of people get good data with 0w20 as well. Stick with what the engine is designed for and you'll have the best luck.
@@kern417 My info comes from the race/drift guys who beat on their oil pretty hard. And yes, the higher shear oils within a given viscosity do consistently exhibit less wear. This is a big reason why Amsoil, Penzoil, and Castroil synthetics generally do well when compared to the rest.
You can't just go to anyone to get info because they drift their cars. Do they have B58s? Stock engines? Whats their oil change frequency? What oil temps do they see? You're talking about something that doesn't relate to the topic at hand. Running that heavy of an oil on your B58 will ruin it. All you're doing is slowing down the oil's flow when it's cold, which is when the most wear happens. Do more research and you'll understand.
@@codyway7424 Race Cars uses heated oilpans. No engine Start below 45*C!
I use 10w60
So what do you think if I use 5w-40 LM in California ?
Should be ok. You could even get away with 0w-30. Do an oil analysis between one of your future oil changes for peace of mind.
I run 0w-20 on my B46 X3. I live in Florida where it’s 90 degrees plus year round. I often see myself pushing the car to the limiter at around 4-4500rpm for no more than 15min at a time sustained on the express lane quite often, been that way since new (30k mi ago). I never run the car hard before turning it off (I don’t like the fans doing the cooling for me). I change oil every 4k mi. Car is stock other than for a dinan piggy back. Is there anything I should be doing to maximize engine life? I know these cars a designed for autobahn use and meant to sustain high speeds
How do you like your BMW with the B46. I just got one. I'm in Miami, Florida. I was surprised about the 0w20. Never had a car with such thin oil. The Deaker told me South Motors they recommend at 60 to 70k to put 0w30. I told they why not 0W30 from the beginning to prevent wear. They Saud I could ask the service dept. to put the thicker oil (0W30), or even 5W30, if I wanted, but the 0W30 flows better . Tgey also told me that the 0W20 provides better gas mileage, wich lead me to believe the thin oil was just for saving gas, but then I run into this video. I'm only at almost 500 miles, and I plan on doing the first change early before 1k, perhaps even a second early one as well, abd then do them 4 to 5 k from then on. Wgat type if oil brand a tree you using, and how do you like the X3, and B46 thus far ?
Do you think the Castrol Edge 0w-20 is still fine for a b58 despite Castrol not having the ll-01 cert?
I would be surprised if it doesn't but if that's the case I'd look at another. Plenty are available that meet the requirements.
Do you recommend using a magnet drain plug ?
It doesn't hurt but I don't feel like it's a requirement
Awesome, so I’m Gucci with the 5w-30.
Whats the difference between the b58 in the 440i and the new Supra/m340i?
I'll try to touch on it in A future video, but look up "B58 vs B58TU." The primary difference is the M340i/Supra HPFP can support more power, and certain models have lower compression than the older engines.
So 0W-20 is a problem being tuned etc? I live in the Midwest but car is always parked in the garage
It Should be fine. You can always send out an oil analysis during one of your future oil changes for peace of mind, but the engine will do what it's designed to.

So happy I found this channel! New B58 owner. Yes I bought used but from a friend. I now see that one 0w20 is fine even tuned but noticed a lot of you guys going 5w30. I’m looking at Liquid Molly and it gives those 2 options. Why are you all going 5w30 instead?
I think if you are in a climate where you don't drive your car in freezing temps then 5W-30 is fine. I also used 0w-20 then 5W40 and now 5W30 just because I like changing things and collecting data. But I wouldn't expect a noticeable difference in performance.

It's most likely too thick. I wouldn't go over 5w40 but you can do an oil analysis to confirm if it's an issue
Way way too thick. You want to use the thinnest oil you can while maintaining hot oil pressure within spec. Fluid is non compressible. The viscosity’s job is to provide adequate hot pressure.
You’re losing power and getting excess heat from your motor having to churn through that thick oil.
