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

-
87 octane is plenty good with the stock compression ratio. -
But with all gas having ethanol, isn't non-oxygenated better for carbs?Comment

Pure gasoline, sans alcohol would be nice.Ed
To measure is to know.

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

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.Originally posted by Nessism View PostCurrent Rides: 82 GS1100E, 00 Triumph 955 Speed Triple:twistedevil:, 03 Kawasaki ZRX1200, 01 Honda GL1800, '15 Kawasaki 1000 Versys

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.Originally posted by Nessism View PostComment

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

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.Comment

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.http://img633.imageshack.us/img633/811/douMvs.jpg

Darn, with so many daily riders it's hard to decide which one to jump on next.;)

Thanks for the advice!Comment

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 StabilComment

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