Gen 3 87 octane????? Is this really a thing?

[dcnblues]

Watch out this summer! I don't want 15% ethanol in any bike, car, or aircraft I'm inside...

Biden will ease restrictions on higher-ethanol fuel as inflation hits a 40-year high

E15 fuel is normally banned from sale in the warmer summer months because of concerns about air pollution. Biden said the U.S. will invest $100

I've ran 90 octane methanol free and 93 with 10% multiple times through a ZX14R, 1441cc, 207hp and there was absolutely no difference.
Doing the same through a 2.7 twin turbo V6 there was, the octane free was getting me 5-7% more mpg.

If the 87 octane is methanol free then perhaps you will be ok vs 90 @ 10% but the first pinging sound back off, and fill up with the good stuff.

suzuki recomends you run on the premium fuel

 

[scotty - 12]

Many stations near me have 87, 89 and 93. I use 89 in this situations. I don’t lug engine and am not racing, so figure it’s about to same. If there’s 90, I will do that. I’ve been doing this with all my bikes for years and never had an issue, even with my s1000xr.

When I pull my camper in the summer, I run Premium to keep my truck pulling and not getting the timing AUTOMATICALLY retarded due to any pinging due to the load. In the winter I run regular. It burns faster and more complete. There is no extra BANG from premium just additives for pre-detonation.
SO: If your drag racing your busa or ride VERY aggressive. Yes, run premium. If you're out on a ride and NEED gas. And the only fuel is regular. Have at it. You're just cruising down the highway. Load is minimal YOU WILL BE FINE...

I accidentally put 87 one day in my gen3. I didn't notice any difference in performance nor did I hear anything different from the engine. I will continue to run 93 because I believe Suzuki said it's best so must be. They have nothing to gain by us using 87 or 93, nothing.

Bringing this back up. Thinking of getting a more mafia tune but I run 89 octane usually. Bike runs great and I’ve run 89 on Gen 2 busa and my BMW s1000. So does mafia tune change timing which would make me change min octane?

scotty you need to ask Chris Moore that question or watch his video on tuning a Gen 3 .
On a statement up top about 15% ethanol and airplanes . Aviation may not use any fuel with ethanol in it . It is 100% pure fuel free from ethanol .
Even running the better fuels things still get dirty from time and usage . I cleaned my Gen 2 injectors about every 8 to 12 thousand miles . They were never bad but a difference was always noticed once clean.
Blended fuel mixtures from winter to summer have differences I can not name , but the BTU is slightly different . This means more or less BTU or power output .
Example ethanol free fuel of 89 octane typical has 15 to 25 thousand more BTU per gallon than the same gallon of 10% ethanol blended fuel .
That change equals more power , and economy . My Gen 2 on pure ethanol free fuel would net 3 to 4 mpg more than blended fuel .
On my Dyno runs of 200+ hp RJ had 92 octane Ethanol free blended with 1 gallon of 110 octane non Oxygenated fuel .
This provided a 95.6 avg Octane rating and was what I ran full time unless traveling across the USA on trips.

So am on a few FB groups and see guys running and dyno on 87. I almost spit my coffee out reading this due to the fact I came to the BUSA from a K7 GSXR 1000. Was I wrong to point out to them that the sticker on the bike and the manual state min 91 octane for the Gen 3????

This is great to know, I was gonna go 87, ONLY because it's new, that is my Gen 3 2023. Now, I will go with the highest Octane available at the station for sure.

Interesting episode of Engine Masters covers this topic on a car engine with 10.7:1 compression. May not apply 100% but worth a watch.

According to that’s video, 87 is a good all around fuel. I used 87 in my Gen 1 and 89 in my Gen 2 and 3. I just worry the timing is different and the Suzuki doesn’t have the knock sensors to protect motor. BMW is known to not have those sensors so those owners use higher octane-wonder is Suzuki is same?

 

[Ked0607]

These bikes run hot anyhow. I know my fan stay on in the summer months on hot days sitting in traffic. Ill stick to premium fuel. Not worth the risk.

 

[TonyM995]

There is but most of the gas you get isn’t always 93, it’s a myth that premium has “cleaning” qualities.

Different brands of gas do use different additive packages. Agreed octane has nothing to do with it.

I always run shell also I’ve had issues with other places.

Shell uses the Top Tier additive package. I’ve had several tuners suggest sticking to stations that have this package.

This is the issue! I've never heard of a car or bike in the last 15 years that didn't have those sensors, but I'm sure the energy companies don't want that well-known. My understanding is that if the vehicle has a computer in it, and your engine starts knocking due to low octane, the computer will adjust and you'll be fine. But I could be completely wrong.

think i read a story about the busa and gas test
dino run with 87 and 91 octane the 87 put out more hp

 

[turtlezx]

read a story some were wish i could find it
took a stock busa ran it on dyno with no changes or adjustments
with 87 and 91 87 put out more hp

Around here all the fuel that is 87 octane is ethanol based......so I avoid it and use higher octane with no ethanol.

Gen1's yes
There's sevreral old threads on it.

 

[Dnyce]

in general terms, you run the lowest octane u can without causing preignition, detonation, knock, all the bad stuff, bcuz it makes more power. As an extreme example, If u don’t have super high compression and crazy timing on a na motor, u don’t need the additional octane benefits of 110, 116, etc. As mentioned above once u add ethanol things change.

 

[sportbikeryder]

Does the fuel "requirement" state 91 RON or 91 R+M/2?
