Will A MK8 VW GTI make more power by using 93 octane fuel even if the car is stock? That was the question that I wanted answered. Seeing as I have already tested my wife's 2021 Audi Q3 with the previous generation EA888 motor I figured I already knew the answer. I put it to the test though to see if I was right and to help everyone else by knowing whether you would see any power or torque gains using 93 octane fuel rather than 87 octane fuel. Enjoy!

I don't think I've ever seen the amount of ignorance that I'm seeing in the comments of any of my videos more so than this one. NO, you don't need to drive 30km, 50km, 150km, 30 min, 2 hours, or repeat cold start procedures to ensure the ECU adapts to the change of fuel in your gas tank. These modern ECU's are INCREDIBLY quick to learn & adapt. I have done endless amounts of fuel comparisons and fuel testing on this channel with short & and long-term analysis of the results we achieved. If the car was going to make more power using a higher octane fuel IT WOULD HAVE 🤣 If you would like to continue to doubt me please spend a few minutes of your day watching the results of a few of the other fuel comparisons I've done to see what it looks like when an ECU has the ability to gain more power from a higher octane fuel. Within 2 to 3 pulls on the dyno, we've seen gains of 40whp in other cases!!! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vdg8DJmKODs.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SoCsF5dRE0U.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5wSrXwOpx_c.html

From my testing on other platforms with the Bosch MED ECU's if you take a stock car, and then do modifications like an intercooler for instance, it'll make the same power (if there is no real knock prior) only it'll just do it at a lower PSI. Would you be interested in testing that? Change absolutely nothing ECU wise, but doing an intercooler and piping and see how the power and curve remain pretty much the same, but see how the PSI it needs to reach the power drops?

@slscamg 9 месяцев назад

Very interesting results. For a while now engines seem to have been able to keep peak HP and Torque numbers with 87 when even just 10 years ago you could tell the first time you had high load mid range pull. In my experience it seems likes you can still get these turbo engines to pull timing on 87 when its crazy hot out and you've been running hard, like 85mph through Texas when its 115f outside. We had a rented Chevy Equinox with the 1.5t and it pulled timing so hard I thought we through a rod. It will be interesting to see if the cooling system is "overbuilt" enough that for those 4-6 weeks of extreme head I won't notice a difference on 87 vs 93. Though, even if I only have to use 93 20% of the year, that is still a huge cost savings.

@VancityAudi 9 месяцев назад

There's certainly something to be said for driving in extreme environmental conditions. I would imagine the car's cooling system plays into that just as much, if not even more than fuel does. This video was to demonstrate what the everyday driver would experience and to show all of those people that use 91 or 93 octane fuel on a daily basis in their Mk8 GTI's the real performance difference.

@SlipAngleG70 11 месяцев назад

Super glad your are showing people these truth telling videos. Higher octane really just means it can withstand heat and compression better. In fact, lower octane fuel is more volitile with a faster expanding flame front. If the heat or compression isn't high enough to cause knock, then the power made at the ignition and boost levels should be as advertised. So many people think running 87 is blasphemy on cars that have 91 recommended. Those same people run 91 octane, then tune their car and still run 91 and don't see the irony. They can run 91 because they had the head room all along. I would say the 91 may start to show a difference with your GTI on stock tune when the car is heat soaked..

@VancityAudi 11 месяцев назад

Good thing it isn't stock anymore 😉

@adamsmidkiff1 24 дня назад

" I would say the 91 may start to show a difference with your GTI on stock tune when the car is heat soaked.." This has been my experience in Arizona summers. Higher octane prevents timing from being pulled when it get hot outside. Will happily drive 87 in the winter, but it's 91 in the summer.

Cool video! Just a question. How did you ensure the car was only using 93 octane on the 93 octane run? Did you completely drain the tank and let the engine run out of 87 oct to endure no cross contamination on the 93 run? Ive seen stock ea888 gen 3 make more power stock on 93 octane so im a bit surprised.

@VancityAudi 11 месяцев назад

We drained the tank completely. The car wouldn't start. Every dyno reads differently. Just because you've seen it make more power on one particular dyno, in one set of conditions doesn't mean it won't make more or less on another dyno in different conditions. This is a EA888 Evo 4, not a Gen 3, like I explained in the video.

Fuel in Texas vs fuel in California is not even remotely comparable. Not to mention the "ol' butt dyno" feelings have been disproven on this channel time and time again.

@NimaSomeh 11 месяцев назад

great vid, the ecu needs a bit of time and kms to slowly adapt to 93 from 87 this is why u didnt see any big change. cheers

@VancityAudi 11 месяцев назад

Please explain to me why you'd assume that. I've tested a ton of cars in this exact same way and if the car was to gain any power it would have happened immediately like we've seen time and time again. Once you reset the fuel trims and add the higher octane fuel the car will make more power if the ECU will allow for it. The ECU's don't need time to adapt. It would have gained within 5 minutes of driving on the dyno and doing 3 WOT pulls.

@NimaSomeh 11 месяцев назад

I ll try my best to explain although I am the worst person at explaining things, so if I had to simplify things... the ECU has a Base map timing and a timing multiplier. you are correct once you reset the adaptations and ecu, the ecu does start at the base map timing, but its using the minimal multiplier hence its tuned from factory to run 87 oct, it will slowly ramp up on timing as it will ramp until knock is present and lower it a bit and lock it there on that range of rpm. theses cars are very advanced compared to most of modern jdm cars. now if you would have driven the car hard for a week and did a dyno test on 93 and then emptied the tank and put in 87 oct, there would have been a bigger difference and a more realistic test on power vs oct. man I just found your channel recently and I love it. cheers @@VancityAudi

@VancityAudi 11 месяцев назад

@@NimaSomeh Thanks for watching. I appreciate the support. Could you explain to me why every other car we've tested on the channel has gained or lost power depending on the fuel we used IMMEDIATELY on the dyno and why this would be any different? I've data logged and dyno tested at least 20 other cars using different fuels and they all have lost or gained power when using different fuels from one run to another once the fuel trims have been reset. ECU's do not need that long to adapt to gain power.

@NimaSomeh 11 месяцев назад

that is an interesting question for sure brother, to be honest I don't exactly know why, but it could be that this car is slower to adapt and it has a safer logic and base map timing or it could also be a very bad batch of fuel you got, it happens actually more often than we think. truck drivers sometimes put 87 in the 93 tank at the gas station tank or the 93 sat the not sold for a while and degraded to 87ish. I hope this helps. Jesus bless you ! @@VancityAudi

Adam, did you datalog the car when testing out the different octane fuels? Any differences in terms of advance and retardations? I recently data logged the 2023 Jetta 1.5T with 87 and 91 octane. Both fuels show no timing retardation but the max ignition advance under 91 was 2.5 degrees higher than 87, so that’s telling me even the 1.5T can benefit from higher octane, so am surprised the GTI doesn’t.

@VancityAudi 10 месяцев назад

I did, yes. Peak timing was 4 degrees on both fuels. Did you dyno test or performance test the car after logging? My wife's Q3 did the same thing where the datalogs showed higher timing advance on the 93 octane and E20 tune and made no additional power.

Did you go for a drive on the 93 gas before dynoing? The later ECUs have a high octane learn that will add a few degrees of timing if they detect no knock during a test event that runs periodically, but it likely didn't have time to run if you didn't take it for a highway drive before doing this test.

@VancityAudi 11 месяцев назад

No we did not. We reset all the fuel trims, drove on the dyno for a while, and then did multiple runs. In the history of doing fuel comparisons over the past few years we've never once seen an ECU ever add additional timing with higher octane fuel because you had to drive the car on the highway first. It has always happened immediately after changing fuels and it did not. Just like it did not on the EA888 Gen 3 motor we tested.

@volkssturm9694 11 месяцев назад

Makes sense you get no more power with 93 octane, hence tuned by VW for 87 octane. Now if the GTI was tuned specifically for 93 octane , yes definetly you would get probably about 10-20 more HP (maybe even more) no doubt because the timing can be advanced, since 93 octane burns in a more controlled fashion. I have an audi S3 8.5 V tuned stage 2 ECU/TCU with FBO with 93 octane and I know the 93 octane fuel produces at least 10 more hp compared to the 91 octane tune. Thanks, cool video Bro.

@VancityAudi 11 месяцев назад

You say that, yet every car we've seen that comes from the factory tuned for 91 octane fuel gains power when we test it on 93 octane fuel.

You don't. As I stated in the video I've done a whole bunch of fuel comparisons on the channel before. Once you clear the ECU and reset the fuel trims, it needs to immediately adapt to whatever is in the tank. In between the 87 & 93 octane runs, I reset the fuel trims.

@stevenanderson5018 from all the fuel testing we've done, on all the different Audi's, the ECU's adapt immediately.

Entertaining, however of little empirical or scientific value. When switching to 93, you need to drive the car at varying loads for a minimum of 30mins to let the car detect, and then adjust for the higher octane. If you do not do that then of course all runs will simply be within margin of error.

fuel doesn't have any impact on power if air is cold enough to make the engine NOT to decrease timing. higher octane fuel would help engine not to make knock and not to decrease timing, and that's why you have "more" power. but if egt is in reasonable limits you'll not gain any power, as showed in this video.

@VancityAudi 11 месяцев назад

The air was NOT cold enough. As I mentioned in the video, it was a warm day (also indicated on the dash of the car). If the ECU allowed for more timing advance, it would have gained more power from 93 octane, which I clearly showed it didn't.

I said I can beleive it's tuned to 91AKI but in most other markets it's not.

Which makes sense since it's the lowest octane fuel in the market and a car should run on that . Most places have 95ron(91AKI as min) . And if there is no power difference between 87v93, either your fuel is dodgy or you have tested it under different variables. Heat soak, temperature etc. You are the outlier on this one. Pretty much any test out there on a VW EA888 engine will give higher power on the recommended octane fuel and lower on the min octane fuel posted on the flap.
