- The Automobile Association of America (AAA) conducted an independent test on the impact gasoline detergent levels, and the results were quite shocking! This video reviews the results from that report and provides context as to the ramifications of fuel injector deposits.
Gasoline engines must atomize and then vaporize the fuel for it to burn. When injectors have deposits, they don't atomize the fuel as well as clean injectors. As such, fuel dilution of the motor oil increases, which increases engine wear.

I worked in oil refineries and fuel storage terminals for years and I can confirm this. The "Top tier fuel" companies like Chevron use their own proprietary additives. They are stored in tanks separately and are added to the fuel as it's being loaded. (Ask any fuel truck delivery guy) The no name fuels use a minimum baseline generic additive.
If you use a top tier gas like Chevron, or Shell, there's no need to use any aftermarket cleaning additives. Some fuel cleaning additives can damage sensitive emission control systems.
All true! I will add that Even with Shell V, when gas goes bad in a vehicle, you should add a Reputable injector/fuel-line cleaner with a tank of completely new fuel. I have several goto's that have performed vehicular necromancy. One is called "Quickshot" by Amsoil. I've used it on naturally aspirated Hondas and Audis to clean fouled injectors etc, and its effect has been nothing short of miraculous. One must follow the instructions To The Letter with these caliber of additves, however. Or else, as you stated, bad things Will happen.
@@ch0wned Have not used Amsoil, yet. But, have used Rislone HyperFuel fuel treatment (bottle has two chambers, one with a PEA and the other with a lubricating oil. It worked awesome! The reason I know it worked was because of how it ran and the oil catch can I have showed black vapor concentrate in it. Usually it is a oil brown.
I’m a BMW technician, so they recommend top tier with these turbocharged, direct injected engine. And I can’t tell you how many cars I’ve seen come in for rough running, and it turns out the problem is they use non-top tier gas. Drain and fill the tank with top tier, and car runs perfectly fine afterwards.
Exactly! Thanks for sharing!
Since my gas tank is kind of small, i run two tanks of Chevron 91. Tank only holds 9 gallons.
Kind of speaks volumes of the engineering design to begin with
Guys, how often should I use a fuel additive?
@@Hover.Tension, I would suggest every time you change your oil
Lake is the Man, Love his work.
Thanks!
I Been using top tier since it came out,and Pennzoil synthetic made with natural gas. Clean and cleaner.Thanks great show
Thank you!
I have a 1995 jaguar that's been my daily driver for several years, it's always had a bit of a rough idle. I have only been using top tier gas the last year or so and the idle has improved a bunch!
Thanks for sharing!
Glad we’ve been able to help your Jaguar run well.
Toss in a bottle or two of Techron injector cleaner. It’s what Chevron uses in there gasolines.
Yeup 98 jaguar xjr switched to shell, been a few months and it does feel better
Use if available Non oxygenated fuel, 91 or 92 octane, as vehicles get older they seem to like higher octane. Around here in MN non oxygenated is around $4.39 a gallon and has no ethanol in it, older vehicles seals in carburetors don't like ethanol.
@6:50 Bought an 88 Camaro last year with oil that reeked of fuel- as noted in the video, multiple leaking fuel injectors (along with a torn pressure regulator diaphragm) had been dumping gas in the crankcase. Hot starts were very hard and exhaust had a very strong gas smell and VERY smoky.
No idea how long it had gone or how much damage had been done (this is a pretty ragged car), but never too late to try and mitigate damage to piston rings, surfaces, bearings, etc. by addressing the fuel system and using top-tier fuels and quality engine oils!
Really appreciate this video. You’re 100% right, run a top tier fuel and supplement with a quality fuel additive, like Gumout with PEA based Carbon Clear, to keep your injectors and intake valves operating as intended.
The Gumout Complete fuel additive works really well. We’ve seen a decrease in fuel dilution in used oil samples when a customer started using that product.
I can say with my experience after using Gumout for long past that it i has so far the best fuel additives range in the world
@@edwardpeders9582 Good idea!
@@you_can_fuck_your_own_ass_69 Gumout
Not for the intake valves, obviously
Thanks for the heads up fuels👍
Any time!
Here in lebanon, our fuel quality is questionable. Unfortunately, we aren't offered top tier gas. Plus the octane rating is very low
I’ve driven years putting RaceTrac in my car. Just recently read about Top Tier. Now I’ve switched to Chevron instead.
Late model motors with cylinder direct fuel injectors have issues with elevated intake valve tempratures that cause the fuel and oil deposits to "BOIL" when they hit the HOT! intake valve backside. All those deposits are because there is no longer a "fuel wash" on the backside of the intake valve cooling the intake valve....DI motors will always have build-up problems no matter what the fuel or how many "BOGUS" aftermarket air/oil seperators you put onto your motor. I had a B7 RS4 Audi...Car was a POS! with misfire codes in less than 30K miles because of debris build-up on the intake valves. The solution? Walnut blast the intake ports....Truly a JOKE!
DI engines are a problem in regards to valve deposits.
First mistake was buying an Audi . Second was not ditching it
@@TotalSeal meth injection is prob the best thing for DI
It's mainly for cleaning whatever the fuel touches but direct injection engines won't help since PCV system directs positive pressure and some oil into the intake to burn it off that ain't the fuels fault that's why direct injection only is really stupid it should've been multiport fuel injected
Wasn’t that the 4.2 FSI naturally aspirated V8? Those were/are notorious for having carbon build up in the intake ports, from what I’ve read/heard. If cars are going to have DI, should be mandatory to come with dual injection mode (accompanying port injection) to ward off this carbon issue.
Thanks for the video. Appreciate the info and will read that AAA article for sure. As a auto technician and an parts inventory specialist for a company, I can testify for sure we are seeing a constant issue developing with DI engines. They are either being torn down to be repaired for fuel delivery issues or they are replaced as an entire assembly because the fuel injection service isn't resolving the issue at hand. Of course this isn't the only factor as there are mechanical issues as well. The amount of on-the-shelve replacement engine parts for rebuild is quite extensive. Currently, there is an issue with Honda's turbocharged engines. There have been numerous reports about oil/ fuel dillution while displaying the oil level to register higher then normal on the dipstick after 3,000 miles . It's quite possible that the actions from the turbocharger coupled to the DI setup may be causing a incomplete combustion process allowing the fuel to be unburned properly and allow the fuel to bypass the rings and end up in the crankcase. It is quite worrisome as some of my customers have DI vehicles and I have recommended my customers to stay at the 3000 mile oil change interval instead of what some of the manufactures recommend which is anywhere from 5 to 7,500k.
Many dealerships are now stocking more BG fuel injection kits as part of a complete fuel injection cleaning service.
I think what needs to be advised to owners who own DI vehicles to use high quality fuels with detergents. However, I'm not sure what would be considered the long term resolution for the fuel delivery is no longer being sprayed on the intake valves as what older FI engines use to be.
Yeah DI def has its shortcomings in the valves department. Can't get fuel on those valves to clean them as in dual injection vehicles. Definitely have to stay on top of maintenance on these cars, especially the turbo ones. If you're saying the Hondas are getting so much fuel dilution, only a matter of time before that really takes premature wear on the internals and even the turbo. That's why I don't bother with turbo Di cars for a long term car.
Appreciate your comment. After just replacing the fuel injectors (out of warranty....) on my wife's 2017 CR-V, we are slashing the oil change interval to 3000 miles until we get enough data from Blackstone to consider extending.
Not a problem. I learned this past summer my sister in law had also her fuel injectors replaced on her 2017 Honda CRV as well. However, they were under warranty. So I kinda question why your weren't? Was the coverage based on milage or the terms of ownership?
Fyi: I learned from a GM source that any new vehicle's warranty coverage from the manufacture starts the moment the vehicle is rolled off the assembly line and not when the vehicle is sold to the customer! This I find is insane and don't understand why this is right. Not sure if this applys to any other manufacturer.
@@carrsllccarrillo6507 good question. we might have gotten hosed; really don't trust this dealership anymore. Any chance your SIL lives in California? They have stronger consumer protection laws; I think 8 years / 80k miles for fuel injectors, mandated by the state.
@@utmichael2008 I reside is in IL. It's highly doubtful the mandates here are as stringent as what California is. So any form of warranty coverage is most likely based on certain conditions that are not implied other then what is stated from the manufacture.
One if the cheapest gas stations in my area sells Top Tier fuel. It doesnt have to break the bank.
Thanks Guys. Very educational....especially the part about P.E.A. (Polyether-amine) and which fuel additives contain it. 👍💯 BTW, I recently bought a high mileage (slightly over 200,00 KMS) 2017 Chevy Spark. The price was right at $4000 CAD. It was a former NAPA parts delivery vehicle. Because of this, I'm hoping it was regularly maintained. Which grade of fuel is best for this vehicle? My nearest gas stations are both ESSO. They don't offer Top Tier gas. I plan to use Gumout on my next two fill-ups.
Some of the cheapest fuel I can find is at Costco and it's Top Tier. Washing the intake valve with fuel is more important than Top Tier. You specifically mentioned direct injected engines having problems early. Manufacturers like Toyota are smart enough to also port inject on direct injected designs so that the intake valves are washed with the fuel from the port injectors. Think maybe that's why they have a lot fewer problems than others who use only direct injection? I have several high mileage vehicles that were born long before Top Tier and they have none of these problems but then they aren't direct injected either.
Absolutely, the combination of port injection and direct injection works extremely well!
Some of the ford motors like the 3.5 and 2.7 eco boosts are dual injection as well. So smart. Don’t think I’ll ever buy a straight direct injection motor
@@ajmedeiros77 Ford seems to have caught on with this. The problem is that even with the added port injection some of these ecoboost engines are still having problems with intake valve buildup. I'm hoping software changes like spraying a little more through the port injectors will fix this. Ford's naturally aspirated 3.5L is excellent and known for reliability.
@@AC_metro Correct...The Toyota 4GR-FSE in the Lexus IS-250 was an unmitigated DISASTER
B58 seems to have fixed this via a redesigned PCV that's better at condensing oil before it reaches to intake.
I have had great luck with Startron fuel stabilizer for storing fuel in tanks/fuel systems during off season. It seems to have smoothed out FI systems on a boat and generator even after replacing injectors. What is your opinion of Startron compared to Amsoil Quickshot? Thank you.
Hey Lake, just to be clear...Top Tear fuel is not just premium octane. It's available in regular octane as well, correct? BTW, thanks for all your help with my S2000 a few years back with your oil advice and break in advice. Driven Oil is the only thing I use.
That is correct. Top Tier goes across all the octane grades.
The best gasoline ever was Amoco Supreme. It had it own tanks, lines, piping etc. from refinery to fuel tank truck, Can't find it anymore since BP bought Amoco.
I use to run Sunoco 94. But they got bought out and the station I used to use closed out.
I remember the fuel was clear and passed through a filter after leaving the pump.
Called "white gas." I remember when it cost about 35 cents a gallon.
@@markstrickland8736 right wouldn't that be fucking wonderful. Cheapest I've ever seen gas in my life was 50¢ a liter here in Canada at the beginning of the plandemic. Roughly $1.40 USD a gallon once you add exchange rate etc.
Amoco Supreme was the best gas ever for small engines IMHO
Thanks for the great video.
I have a question!
I am testing various fuel mixtures for 2-stroke Enduro racing engines and I have noticed during the tests that a very important parameter is the volatility and vapor pressure, in two-stroke engines, before burning, the fuel passes through the engine to lubricate the bearings and then it is introduced into the combustion chamber, this process heats the fuel favoring its evaporation, I have discovered that if the fuel is very volatile the operating temperatures rise, the carburetion becomes lean and the engine performs less, probably the pressure of the vapor in the Karter makes it more difficult for the new mixture coming from the carburettor to enter...
This happened to me using MTBE, switching to isobutyl alcohol which has a much lower volatility, the engine runs cooler and performs much better.
The question is this:
in a 4-stroke engine, especially port injection, can the vapor pressure during injection cause back pressure which reduces filling during the intake cycle?
Sorry for the length of the message and thanks in advance for your reply.
Thanks for watching and the question. If the fuel is too volatile, it can reduce the intake charge efficiency.
We recommend farmers treat their bulk fuel when it is delivered as the cleaning and lubricity additives have shown to be well worth the money in the long run. You can buy a whole lot of fuel conditioner for a $10000 fuel system like a lot of these new big diesels have.
Absolutely!!!
Interesting video. I wish you would have expanded on how to find, or who has top line premium fuel? Especially when you are on the road and can’t look it up.
Also, where can we get non ethanol gas? I ran into some and my mileage went up about 4 mpg!
Here you go... toptiergas.com
GREAT/INFORMATIVE video! I agree on oil additives. Just change more often than required (5,000 miles/6mos), ESPECIALLY for direct injection. What do u think of "Guaranteed To Pass Emissions"? I used to use on my 97 Camry & I pulled the plugs & they were like knew. One yr, I didnt add to a full tank of gas & I fried the plugs & had to replace them. Thats how strong it is.
Sub'd & 👍'd.
Ethanol free gas (wawa) or top tier fuel for a plug-in hybrid car (Chevy volt)?
I read that AAA study when it came out and I've been using the top tier Shell every few tanks in my vehicles, even in my Toyota that usually runs cheap 87.
Thanks for sharing
Great info! But based off your expertise and data, does Chevron, Shell, or Exxon have the best additive packaging to ensure fuel system longevity in GDI systems?
No..GDI engines need 3,000 miles Oil changes with 0w-20-30-40 Class 4 Syn..Throttle body cleaning every 3,000 miles..The intake valves do not get lubricated with fuel like Port Injection..High Pressure to injection straight into cylinder causes fuel passed rings to crankcase..
Oil dilution effects..Start DIY Methods.......
What is a good fuel additive? What brand and kind? Thank you so much for any info.
Any PolyEtherAmine based additive will work well, and the Gumout Complete fuel system cleaner is a PEA additive.
How much does top tier fuel do for DI engines. ?
I've been using Techron Concentrate Plus Fuel System Cleaner since my Subaru Forester XT (DIT) reached around 25k and noticed engine performance decreasing or lacking. It turned out that one of my engine's fuel injectors might have been clogged up with carbon deposits using 91 octane Arco gas for about 5 years, used the cleaner, and my SUV runs like new. I know many states vary but in California, most well-known gas stations are supposed to meet or exceed the standard in additives and detergents. That being said my SUV is supposed to run 93 octane, but you can't get any in the state and always check your owner's manual what type of fuel is allowed in your engine. But TBH you should really just care about doing regular car maintenance when you are supposed to which a lot of people don't understand.
Thanks for sharing!
The owners manual is lame. X
Doesn't really tell a lot more in details other the. Just a few here and there infos on what the vehicle is equip with and how to operate it only. I find more in depth infos on the web then what the owners manual book tells me.
Having higher detergent not also burn cleaner but more efficiency. This I still believe in. Having more detergent tend to have less water in it.
I find it interesting that BP is no longer a “Top Tier “ designated fuel.
I just found out also... BP no longer top tier.... I am concerned...what do you think ??
@@rickski3769 I don't know for sure but I'm guessing BP didn't think paying for the licensing for "Top Tier" designation for worth it to them. It is probably still a quality fuel.
They stopped paying for the title. 99% of people have no idea or don’t care.
You know who is tho? Arco!
@@stolenhal0 Yes. Here in southern California it's also some of the least expensive gas.
What’s the best fuel injection cleaner ?
Since brand new (apart from the fact that I don't know what fuel quality my Canadian Chevrolet dealer put in the tank when I got the car...), my 2022 Chevy Spark 1LT is on Top-Tier gas from Shell or Costco).
I Only use Chevron/Texaco 89 octane gas that contains Techron additives In my
Ram 2500 4x4 HEMI, It is Top tier
Are fuel additives works with diesel too?
Always learning something from these videos. Which fuel additive brand do you recommend?
Chevron Techron Complete or Gumout All-In-One
@@TotalSeal... Thank you very much.
Redline is a great product.
I use nothing but shell or Kirkland fuels (Costco) & both are a top tier fuel ! I’ve never had no issues with using either one . I used Lucas compleat fuel injection cleaner . & also tried Red Line fuel injection cleaner. That two are kinda bit pricey but they do work great. I’ve used Chevron’s fuel injection cleaner . Those three are good ones . My take is stick with works .
If you use a top tier gas there's no need to use any cleaning additives. some after market additives can damage sensitive emission control systems. I heard that Costco is using a Chevron additive in their fuel. I heard that from Chevron operators actually.
Informative video thank u sir.
Thanks for watching and commenting!
How does E85 compare to top tier?
And is there a top tier e85?
Absolutely fuel maters!!! Awesome video!
Thank you!
You did not mention if you are discussing port or direct injection
Why didn't y'all credit ChrisFixIt for the fuel injector clean vs dirty spray videos?
I’ve read some tuners for Ford Mustang Ecoboost I4 are telling customers not to use Shell gas as the additives promote knock in DFI engines. Any input would be appreciated.
That's a new one on us. The Shell V Power fuel has a fantastic additive package that should reduce knock.
add 2 oz of Redline SL-1 or 1 oz of Amsoil PI to every tank. I have come to an understanding that even top tier means nothing for some cars in some conditions , at some gas stations. I use Shell Vpower Nitro plus in my S2000, and still it wasn't "quite enough".
Everytime your car is runnign, it is either cleaning or getting dirty. You want the engine to maintain equilibrium of CLEAN. Not just throw in a bottle of PEA every oil change
So it looks like pretty much all name brand gas stations are top tier?? Thanks for the videos!!
No. Not all all. Just do a search for top tier fuel. There’s a website that lists all fuel brands that are top tier.
I my area, Race Track, Kroger, Sams Club and Walmart, do not sell Top Tier Gasoline
220k on 06' 3.0 Duratec. Dang right...fuel maters. Pulled the lower intake runners to replace the gaskets (seals) and the valves were spotless using Amsoil oil/top end lubricant/P.I cleaner.
And this is why I went back to amsoil. I had no problems before while using amsoil. Switched all over the board and started having issues again. Now back to amsoil. I know it's expensive but it's worth it.
I’ve been using Amsoil for 10 years now, I do regular oil analysis and I do drain intervals that will probably generate a ton of hate here, but even changing my 0w30 SS every 20,000 miles in a 5.7L Hemi that tows, plows and hauls, I’m at 170,000 miles with zero issues and it still burns less than a quart per 10,000 miles! I’m a strong believer.
Is PEA the short name for the polyether amine you recommend?
Yes
II Called Chrysler Customer Service a while back and their recommendation is to only use Techron Fuel System Cleaner. I'm interested in taking very good care of my current car, my '12 Chrysler 200 Touring convertible with the Pentastar V6 engine. I use the same high quality oil that Chrysler recommends for their modern Hemi engines, Pennzoil Ultra Platinum synthetic made from natural gas. My car has lower use because I'm retired so I make sure and change oil twice a year or about every 2,500 miles.🚘
Techron is a PEA based detergent additive.
I got burned by using soley E85 with limited use GMC SIERRA. The deposits on the intake valve were as your opening page. Found out later that e85 fuel has limited to no additives. Thinking all along that the ethanol would be clean. Not the case.
Sorry to hear that, but thanks for sharing your experience.
I agree. But I have been thinking lately that the higher levels of detergents in top tier fuel still ame their way into crankcase eventually, therefore cleaning out the film of oil inside the engine more than the regular fuel(of course the injectors won't be as clean with this one).
With this in mind, what should I do?
Thant’s not the way it works. The Top Tier fuel additives do less damage to the oil.
Glad I came across this video! I'm going to look for it now.
SIDE NOTE: Seems to me some of the GM engine failures were probably because of bad fuel.... Maybe someone knows more on that.
If my owners manual says 87 octane is recommended, but the oil companies like Shell, Mobil , Chevron, Marathon (all top tier last I looked) puts more detergents in the 93 octane fuel than the 87 octane fuel, I looked it up on there websites should I use 93 or at the least put a tankful of 93 in about every 5 or 6 fill ups ?
That depends on your budget, what you're driving, and your typical driving habits. Most say that using higher octane than recommended is a waste of $. If you're driving a car with GDI, a little more detergent is good.
If you do short trips and don't stretch out the engine once in awhile, it's more susceptible to carbon deposits. In this case, a bottle of Redline S1-1 every couple months and the good ole occasional Italian tuneup will get you a lot more bang for the buck than 93 octane.
It’s true top tier and higher tier gas get better MPGs.
Which additive contain that poly ether amine? or will it say it on the bottle. sea foam and locas don't have it in their regular ones. I checked the sds.
Most will say on the bottle. Chevron Techron and Gumout All In One are both PEA based.
Okay, this is an age old question: I have been using pure gasoline in my 1985 Toyota 4runner, I found it get's 22mpg using pure gasoline, no E10 crap. and it sit's on 35's with 5:29 gearing and 22re with 5 speed manual transmission. when I went to E10 one time, I found it got 17mpg. so I stay with pure gasoline. pure gasoline better to use????
yes it is, also keeps the engine cleaner. ethanol is awful and only helps feds and corn farmers
Could I just add Marvel Mystery Oil to my gas tank at every fill-up? There aren't any top-tier pumps in my area.
No, Marvel Mystery Oil is not a detergent. You could run Gumout Complete or Techron Complete with every fill up instead.
I did the MMO for years in my 3.5 VW Nissan. I believe (hope) it helped w/ lubrication of moving parts, but it didn't noticably clean anything that had deposited previously (per the real mechanic who I took her to for everything past my tool and skill level). 💫
Great knowledge
Thanks!
So, do the deposits on intake valves on direct injection engines comes from where? Reversion?
Is it aggravated by auto shutoffs/ restarts?
I have the same question. Possibly crankcase vent being dumped into the intake? I know that was a issue on some Ford EcoBoost engines. Look up FordTechMakuloko
DI injected motors suffer because the tempratures of the intake valves run hotter than a port fueled motor. Becuase there is no fuel wash on the backside of the valve like in a port injected motor....The small amount of fuel that enters the intake port during the "Overlap" period where both the intake and exhaust valve are open tends to boil on the back side of the intake valve building up deposits. Yes oil vapors too can contribute to this but, I argue it is the fuel boiling and heated valve tmepratures that cause the buildup. Many manufaturers like Porsch and Lexus have gone to a split injector system on the current motors to help resolve this problem, having both a Direct Injection system and port injectors in their motors.
From reversion and from oil mist moving through the PCV system to the manifold.
@@TotalSealmy question is if you use a good quality oil like Pennzoil ultra platinum and use top tier fuel, would that mean the “want” or “need” for an oil separator would be void? Since both the oil and the fuel have great cleaning abilities?
In Canada, most gas stations are run by very large companies that have their own additive packages. How does Top Tier compare with Petro-Canada's Tactrol additive, or Chevron's Techron etc?
Both of those should be Top Tier. Chevron's Techron is Top Tier.
I Alberta the only top tier I know of is Shell and co-op.

Do you know what additives contain PolyetherAmine? I've checked many and they either have their own patented name for it, or they don't contain it. I would like to know what I'm buying.
The Gumout All-In-One fuel system cleaner and Chevron Techron Complete Fuel System Cleaner both contain PolyEthe Amine.
@@TotalSeal : Thank you!!
BG additives also. BG is great stuff
G'day Lake and also Keith. Lake I have been binge watching a lot of your informative videos. I am lucky to have an older brother who was a mechanic . He started his apprenticeship in the late 60s. He and his petrol head mates all swore by regularly changing oil and filter and yes pre loading the oil filter with fresh clean oil. I wonder who else swears by this Lake 😉 I never thought I would ever see the day when I was told by an expert to PEA in the gas tank. Your famous saying not speculation but fact with science. Best regards to you family friends and viewers all oround the globe.
LOL, love the humor, and thanks for watching!
Great video, it all starts with the fuel.
Thanks!
Would it be better to use a non ethanol 90 octane fuel and add Tecktron or Seafoam than a top tier 93 octane fuel with ethanol in a car that isn't driven every day?
Great question! First off, don't use Seafoam. Second, the Non-ethanol 90 plus Chevron Techron Complete Fuel System Cleaner would be an excellent combination for a vehicle that is not a daily driver.
The only additive I pour into my fuel system is Top Tier gasoline. So far, I've only got 233,000 miles on my Saturn Vue - not usually considered a long mileage auto.
I've been preaching it for years... Top Tier is the only fuel meeting my standards. If you don't want your engine parts literally being worn away every time you fill up, find a top Tier gas station near you, In the South, we can regularly find the fuel at COSTCO, QT (Quick Trip convenience stores) and most of the big name dealers like Exxon, Shell, etc. Fuel prices are generally great at QT and COSTCO. Even if it's a few pennies more at the pump (in SC QT and COSTCO offer the lowest fuel prices in the area, you'll save in the long run with Top Tier fuels.
Does your Vue have the Honda V6?
So would an occasional water/methanol injection cycle help clean the valves on a DI motor??
Yes!
Gumout all in one, stp ultra 5 in 1, berrymans, redline sl-1 are some good working cleaners however clean boost max is probably one of the best if not the best fuel system cleaner available.
Thanks for sharing.
I wonder if a propane conversion would solve most of these problems since it's a much cleaner fuel from the get go. I know there are kits for DI engines available now (which would benefit the most), but I don't know if the propane injectors in those kits are used for DI or convert them to port injection.
I don't think so. DI engines are the ones having these problems because there isn't liquid gasoline (a great detergent) continuously washing the intake valves. There's quite a few practical problems with converting a DI engine to propane too like how you would get the fuel into the cylinders. You certainly couldn't run it through the high pressure fuel pump. How would you even convert to port injection? That would require changing the intake manifold to one with injector holes, which probably doesn't exist for a DI engine. If keeping a vehicle long term with as few problems as possible is your goal, I'd suggest avoiding direct injection altogether. In the real world I'm not convinced that there are significant efficiency benefits from DI, but it sure causes lots of problems.
@@averyalexander2303 Prins (a Dutch company, IIRC) already makes kits for DI engines (there are videos on YT). They add a second set of injectors for the LPG, but also keeps the original injectors so you can also run on gas. I am just not clear if the added injectors are for DI or if they replace the intake manifold to do port injection. As for my comment on carbon build up, I understand that gas in a port injection system cleans the back of the intake valves. What I am wondering is if running a DI engine on LPG reduces the amount of carbon build up because it burns much cleaner than gas, so instead of "washing" the carbon build up, you simply don't create it in the first place (or at least, you reduce it considerably).
Propane would be cleaner.
Byproduct of burning propane is CO2 and H2O. Much cleaner. An intake manifold could be modified for propane. Drill a hole
Which fuel is #6????? It seems to have done the best!
I only sue top tier fuel in my car. Sadly I'm going to switch to an e30 blend later this year and no top tier stations by me sell e85 :(
today, the fuel matters even more than oil, also from experience even the Top tier fuel will yield to deposit on injectors, especially GDI, so you will need to put a good PEA detergent at least every oil change. With even cheap OBD2 readers you can see live fuel trims to experiment.
Right on!
Is it still OK to buy premium fuel? Even though it's not top tier and then use Gumout multi system fuel cleaner?
Yes, just use a fuel detergent additive to keep things clean.
Excellent , very informative thanks very much.
We are happy to help!
Great information! It amazes me that companies are allowed to sell such dirty fuels. Now next time someone tells me I'm too picky about the gas I use, I have a video to point them to LOL. Quick question. With top tier fuels, what are your thoughts on using 93 octane in engines that only require 87 octane? I understand that more octane than required to prevent knock isn't beneficial and that high octane fuels don't inherently burn cleaner, but is it common for them to contain more detergent additives since it's their "premium" product?
Great question. The best fuel to use is the Premium Top Tier, that will do the best job cleaning and preventing deposits.
@@TotalSeal That's what I thought, thanks. I have never been able to get anything close to an answer out of the oil companies about this either, they just say vague things like "All grades of our fuel meet or exceed top tier standards" or "Our premium fuel contains 7 times more detergent additives than the minimum EPA requirement". Considering the price difference between 87 and 93 octane top tier fuel, maybe a better option for engines not requiring high octane fuel would be to use 87 octane top tier with a small dose of Techron, Marvel Mystery Oil, Lucas fuel treatment, etc every tank, it would be much cheaper and maybe even more effective?
@@averyalexander2303 Using a Top Tier 87 along with a PEA based detergent additive (which rules out one of the additives you mentioned) is a great alternative.
@@TotalSeal That's what I thought, thanks. Do you think there's a benefit to extra fuel system and upper cylinder lubrication provided by some additives? I'd think a little extra lubrication would help keep the electric fuel pump, rings, cylinder walls, etc healthy over the long run and likely help the rings seal a little better?
@@averyalexander2303 We don't recommend any type of fuel lubricity additive. The engine oil and cylinder finish are what provides the proper lubrication and seal for the rings. Only use the detergent additive in the fuel to keep the injectors and valves clean.
Is Shell regular also Top-Tier... ? Even if it not Nitro+ etc?
It should be.
@@TotalSeal ok thanks for the follow-up :)
yes
I used the chemtool b12 to clean my fuel injectors of my 2015 Scion xB, with a 2.4L 2AZ-FE. It literally cleans my internals pretty well.
Had no issues with them. And for a bit more affective, I put that bottle before refuel with gas. Not just regular 87, for now few time individually a year using 93. It helps clean them out.
They are pretty swell stuff.
It’d got baby miles, 74k+ miles. No issues.
2: I still use Mobile 1 gas station with no issues. But I sometimes use from shell because they have the a bit better additives inside the gasoline that makes it more efficient for ur vehicle, than other gas stations.
Again, I had no issues using the ones I use for my specific vehicle.
Be careful with Berrymans it has acetone. Acetone is put in fingernail polish remover. Stuff can maybe harm gaskets and seals if left in to long. Use it when you take a long ride.
@@arthursmith643 what’s the percentage of the acetone it carries, on berryman’s b12?
There is no acetone in b-12. The solvent that eats rubber is xylene and ethyl-benzene, with the concentrations being ~50 and ~10 percent respectively.
@@boeginus6732 and it’s harmless?
@@toyotabrony For the most part, race cars sometimes use 30 percent toluene/xylene in their fuel to increase octane. It is still a solvent, so I wouldn't leave it in the tank for too long with all the rubber in the fuel line. You could also add some marvel mystery oil to your tank with it, to act as an oily barrier for your rubber parts. Running both is good for lubricating and cleaning old fuel pumps.
The question I have , and have not found a definitive answer is.... If I buy ethanol free fuel, such as for boats or OPE use, are there any specifications for detergent additives in those fuels? There is a dedicated hose on the pump, and the fuel is "ethanol free 91 octane". It's priced higher, and the assumption would be that most people would not put it in their cars for road use, but it is popular in the boating and motorcycle communities. Does it get a dose of detergents, or should I be manually dosing Techron, Regane, or Redline SI-1 at fill up? I use it for winter storage to minimize the green crust, and when available, usually opt for it when filling the bike. What say you Oil Geek and YT?
The non-ethanol blends must have the EPA minimum detergent level, do these fuels would benefit from a Poly Ether Amine based detergent additive.
Is there a top tier diesel fuel in Australia
Check their website
Most of my mileage is in short in town trips with the engine barely warming up. I always use Top Tier name brand fuel and dump a bottle of Techron in the tank after every oil change at 6 months. No issues at all in 14 years.
That’s a great practice!
@@TotalSeal what do you qualify as engine warming up? When the radiator fans turn on?
so do fuel additives not have any effect to help clean the combustion chamber when we use low octane quality gasoline?
The Poly Ether Amine additives do help clean combustion chamber deposits, even in non-Top Tier fuels.
@@TotalSeal what product to have poly ether amine?
@@pancarmuslim8797 Gumout Complete, Chevron Techron and Red Line S1 are all Poly Ether Amine based.
@@themotoroilgeek
Can this product be used for motorbikes?
@@pancarmuslim8797 Yes!
Please make a vid about oil additives!
That is coming soon on the @MotorOilGeek channel
@@TotalSeal yes!
Top Tier fuel will help keep your fuel injectors clean. This is important for all engines. This is VERY important if you have a GDI engine. You can always add some Techron to your fuel, but Top Tier fuel does a better job of keeping your injectors clean. Top Tier fuel will NOT clean your valves if you have a direct injected engine. Dirty fuel injectors WILL cause carbon build up on your valves IF you have Direct Injection.
Shell, Chevron, Mobil or Costco.... Which one has the best additives????
Shell
I’ve been using gum out all in one and have to say it’s been great
We appreciate it
Top tier 87 octane in my Honda is really good
Does 10% Ethanol make any difference, or offer any help ? Very few of the Top Tier companies are in " The Peoples Republic of Illinois"
Nope, you need the Top Tier additive package. You can use a PEA based fuel additive to offset the lack of Top Tier fuel.
@@TotalSeal Isnt ethanol what causes deterioration of gaskets/metals?
Whats the best brand fuel
The Shell V Power Premium is a great fuel (for pump gas).
@@TotalSeal thank you. Is this the best brand from all of them. What about if I use the lower or higher grades does this recommended brand change?
So which gas is considered Top Tier fuel???
Go to toptiergas.com/licensed-brands/
Is there top tier 87 octane as well or just premium?
Yes, there is 87 octane top tier
Which pump gasolines are top tier?
toptiergas.com/licensed-brands/
Basically all the name brand gasolines from the Oil Majors - Chevron, Exxon-Mobil, etc.
It will HAVE top tier stickers on pumps. At least we do on PA. Even our GetGo from Giant Eagle Supermarkets has them. No Shell near us.
Valero makes the best fuels!!
I went to the store and nothing tells you what is inside the bottle I’m not sure what to buy
Check out the top tier gas website
So the guy who fueled before you with regular, leaves some regular in the tube and you won’t get full premium octane.
That’s true
Our Costco has top tier fuel. Are all grade considered top tier or just the top octane premium top tier?
All grades should be.
Do you still see these deposits on port-injected engines with LAC/non-top tier fuels?
YES!
Can anyone confirm if arco actually top tier? Because it’s the cheapest gas here in california
Check the TopTier website. They have a complete listing.
Is PEA good for diesel?
No. Diesel is different
What is the chemical they add to top tier diesel?
Is top tier better than no- ethanal fuel?
Yes
Valve cleanliness has no reflection of fuel detergent in direct injection engine.
I can't say for yall but around here, especially after the pandemic top tier fuels are borderline impossible to find. Chevron, Shell, Exxon and Mobil, etc have all removed the top tier logos from their pumps sighting sourcing issues. I thought this would be temp but nearly 3 years later it is still a thing, with Exxon and Mobil here only advertising it for their 91 octane fuels.
At this point I'm just buying a bottle of PEA cleaner and using that once every oil change, I still try to use a reputable brand of fuel but I'm no longer paying the extra $0.20-$0.25 a gallon over Walmart's fuel since I'm not getting the benefits of top tier.
WOW! Going with the PEA additive is the right direction.
