Best gas for gs1000

[CJS GS1000L]

What are your thoughts? 79 gs1000L, un oxygenated 91 octane?

[JJ]

87 octane is plenty good with the stock compression ratio.

[CJS GS1000L]

But with all gas having ethanol, isn't non-oxygenated better for carbs?

[Nessism]

Pure gasoline, sans alcohol would be nice.

Buy it, burn it, All good.

[JJ]

I have run 10% ethanol, and ethanol-free. No difference.

Maybe urban legend but some people claim they get better mpg with real gas.

I have. Not much though. Most of the EPA fueling issues came with carbed bikes from the early 80's, so many of the older GS's may not be affected. Makes them run slightly lean, so the tendency is to give it more throttle to get the desired results.

There's no doubt about getting slightly better gas mileage. You have to burn about twice as much alcohol to make the same power as gasoline. The mpg gains are very small, and don't come near offsetting the added expense.

87 octane 100% gas is what I run.

[JJ]

The only pure gasoline I can get locally is 93 octane premium. That's what I run in the CTS-V. Everything else runs great on 87 octane with ethanol.

Use 87 octane gas. If the bike sits for long periods then add some Sta-bil Marine 360 to combat issues with ethanol and subsequent water absorption issues.

Thanks for the advice!

All we can get in Billings Mt that has no alcohol is 91 octane premium so that's what I use in everything, Some places don't have that option though so Id try the Stabil

[CJS GS1000L]

So if I do have 91 non-oxygenated available, I should use whenever possible?
