what octane?

Speaking of stabilizer... any suggestions on what kind to run? I'll probably be riding my trackbike infrequently enough that I should use some.

Any Sta-Bil is better than nothing.

Would you guys choose 91 w/ethenol or 87 without?  Those are really my only two options around here.  Could go to the airport but thought 100LL was bad for your engine (lead).

No one answered my question yet.

 

Better to have a bit lower octane without ethanol or higher with?

Star Tron also works, Stabil it good too.......

edit: re-read the question...

Stick with the ethanol-free 91.

Once you have an adequately high octane number, a higher number does nothing more of any benefit.  So, if the non-ethanol fuel is at least 90 octane (pump labeled AKI), then it's a better fuel. 

 

The octane question simply doesn't bear on the matter as long as both fuels are a high enough number, so all that remains is whether you want ethanol or not, and you don't.
