Thanks for the test! I've always run 87 in my car because I don't have any performance mods, but good to know I can get more performance with it running at 91!
Not a placebo. Put in 92 and the car is definitely more responsive. Been using 87 on our 21 Touring with 13,xxx bought brand new this whole time. I always thought it was suspect in the manual when it said 87 “or higher”. I guess if Honda officially recommended 91. It would turn off potential new Accord owners so, they say 87 or higher. Higher being a little more oomph. Definitely staying on 92 now. It’s worth it imo for the 20 cent difference per gallon.
I owned two CTRs before buying a 22 Accord 2.0t. I plan on eventually doing a Hondata/Phearable Stage 2 tune with stock parts and just use Calif. 91 octane in the meantime. The stock car pulls pretty hard even stock and is impressive acceleration wise already compared to the CTR. I’m looking at long term reliability of the 2.0t so an extra 20 cents per gallon is worth it to me for when I drive my spare vehicle. Thanks for the informative video!!!😁👍
Thank you! I currently own a 2022 Accord Sport 2.0T and had use 87 on my car. I also ran some research online and putting 91 doesn't really show a massive difference than putting 87.
Nice! I bet if the Accord 2.0T was driven around for a while on 91 octane to allow it to adjust to the higher octane, and then it was fully cooled off, then run on the dyno again like the first run using 87 octane, I bet the numbers would have been even higher. Where I live in GA, we have 93 octane... I also installed drop in K&N Air Filters into my naturally aspirated '15 Infiniti Q50 3.7 RWD, and we all definitely notice a difference in the sound and acceleration... Especially above 4000 rpm. It felt like the difference between WOT during an 85 degree day, versus WOT during a 45 degree day. Very noticeable, surpringly. Now, in a forced induction vehicle like the Accord 2.0T that responds to mods better than N/A, a K&N filter combined with 91 octane, or 93 octane where I live, would probably be a very noticeable difference in acceleration vs stock when it was on 87 octane. I'd love to know how much it gains on both 91 & 93 octane with a K&N filter. Anyway, thanks for the great video!
The car did have time to adjust to the different octane before I put it back on the dyno 👍. As far as the air intake filter, I did a whole series of videos testing various ones - checkout the channel playlist to see the results 😉
I owned my 2018 2.0t 10AT for about a month now and clearly the car is meant for 91 and its not even close.While yes it can run on 87,you can tell its not as responsive as it is on 91.The car feels much better to drive on 91 also being more healthy for the engine.
Another good dyno video. You showed why ‘peak’ numbers aren't so important when comparing mods (octane in this case) on the same engine. Different pulls peak at different rpms. @5:06 runfile6 with the lowest hp, peaked at a lower rpm than the other three pulls. I think you showed why the delta at a given point is more important.
Thank you, Nutfield for your positive comment. 👍. I’d take solid gains in HP and Torque running across the RPM range over peak numbers any day - although I’d prefer to have both 😉
I just bought an Indian Scout Rogue. The sticker on the fuel tank says to put 91 octaine minimum. Never even bothered to check fuel differences until now, always just put the cheap stuff in my car (Toyota Corolla) and my old bike (Honda Rebel 500)
Most cars that call for premium fuel (91 octane or better) will not perform at their best without it. While most modern cars can adjust for lower octane, some older cars cannot, and you run the risk of damage to your engine if not using premium gas.
The plots only show 3500 and up. Octane makes the biggest difference at lower rpm and high torque load where preignition is the limiting factor. That's why high octane makes some engines feel more responsive even if peak horsepower isn't much different. That might be hard to measure on a wheel dyno if you don't have a manual transmission.
I’m glad someone else understands this. In those situations of high load low rpms the difference in timing between 87 and 91/93 can be pretty significant. It can be the difference between the need to downshift versus staying in gear going up a hill.
Glad to see you got it right this time I knew this all along. Last year's video was a sham. It's a fact that turbocharged cars generally will produce more horsepower and torque on a higher octane gasoline. Good video!
Finally the argument can be put to rest in the accord FB groups lol. Proof is in the pudding. Gas quality can cause variances but ford cars for example make advertised Hp on 91-93 fuel.
The fuel itself doesn't add power, timing adds power. The more advance in your timing you can safely run without detonation, the more power you can make. Higher octane fuel is actually less volatile so it allows higher compression and more aggressive tunes. Low octane ignites easier so in a high compression engine it will detonate before the pistons reach TDC, Pre-detonation. The computer will adjust the timing to the fuel and give you more power from the timing advance that higher octane allows. The computer will set more aggressive parameters in the tune for higher octane and you usually will feel a nice bump up in the low and midrange power. You can get up to about 10 to 20 more hp for every 2 degrees of timing advance, depending on the engine size and design, altitude etc.
I think its important to note that a lot of vehicle KNOW what gas you put into it and adjust accordingly. 91 octane into any 87 octane wont increase any power unless the engine knows that it can swap over to its factory 91 octane tune
I've never heard anyone argue that. Argue that there isn't enough difference to justify spending 60-70 cents more per gallon yes, especially now that the racist rapist devil has caused gas prices to go up between 1.50-2 per gallon
Using 91 bring better engine life and kepts everything cleaner inside so tech just speaking even if you aren’t getting the power you desire out of 91 your still helping your engine
From what I’ve seen, a Type R turbo on the Honda Accord can add 40-50 whp! Checkout the channel page as I have several videos in which we dyno test various mods, including the KTuner Stage 2 and Phearable Stage 3 👍
Wait, can you run 87 octane on a Ktune? I am interested in getting a Ktuner, but don't want to run Race tunes, just a little more aggressive tune then sport.
Very simple folks... Octane is based on compression ratio no I don't give a crap what the ecm can accommodate for run the octane based on compression ratio and boosted or na.
Thanks for the test! I've always run 87 in my car because I don't have any performance mods, but good to know I can get more performance with it running at 91!
Appreciate you leaving a positive comment 👍. Thank you. Glad you found the video informative.
I really enjoyed this! Glad someone is looking into this and showing the work behind it instead of just posting numbers!

top speed v acceleration = yes!

It's called power under the curve. That's where most people drive!

Thank you, Tariq! I appreciate the positive comment, and support 😁👍
Makes a difference if the manufacturer says to use 91. The knock sensor messes with the timing with lower octane from what I gather.
Actually, Honda recommends using 87 octane gas or higher.
The Miata recommends 91. Perhaps the Honda knock sensor is advancing the timing too.
@@demonsaint1296 yea on my 2010 acura tsx (basically a honda accord) it recommends 91
I think its important to note that a lot of vehicle KNOW what gas you put into it and adjust accordingly. 91 octane into any 87 octane wont increase any power unless the engine knows that it can swap over to its factory 91 octane tune
Yeah and with some that don't happen in minutes it takes drive cycles and or on off cycles etc.
This should clear up some internet arguments. Have heard so often that octane makes no difference on a stock tune blah blah. 😐
At least during this testing, the difference was readily apparent 👍
I've never heard anyone argue that. Argue that there isn't enough difference to justify spending 60-70 cents more per gallon yes, especially now that the racist rapist devil has caused gas prices to go up between 1.50-2 per gallon

You should always run 91 or better octane with any turbo charged car
Hondata did a dyno to on a 2018 2.0t MT… they say it gained 9hp with 91…. I’m confused
Have you dyno the accord by swapping with a type R turbo? Would it make any difference? How much power can I get by k tuner v2 with front pipe?
From what I’ve seen, a Type R turbo on the Honda Accord can add 40-50 whp! Checkout the channel page as I have several videos in which we dyno test various mods, including the KTuner Stage 2 and Phearable Stage 3 👍
Thanks I will check all your videos 👍
I wonder how much this would affect a V6 accord?
Wait, can you run 87 octane on a Ktune? I am interested in getting a Ktuner, but don't want to run Race tunes, just a little more aggressive tune then sport.
You should be running premium fuel on the KTuner tunes.
I have a 2020 accord 2.0 I have no mods and planning on leaving it stock. Should I put 87 or 91 fuel ⛽️? Thank you
Honda recommends 87 octane or higher… if you’re not planning on adding any modifications, then I would stick with 87 octane.
Very simple folks... Octane is based on compression ratio no I don't give a crap what the ecm can accommodate for run the octane based on compression ratio and boosted or na.
So it's true some people can tell a horsepower by the seat of their pants
😂
If I put 91 in my 1.5t will it go faster
No
Imperceptible difference in practical driving. No reason to use 91 octane.
Could be CO has better quality ⛽️ than MA.
