Ethanol & Octane

Vansaki · April 24th, 2023, 03:19 PM

Since cleaning my carbs a year ago, I have decided that I want to do anything I can to avoid doing it again in the near future. I want to use a non ethanol fuel. My option where I live is 90 octane non ethanol fuel. Will the 90 octane hurt my motor (2007 ninja 250) ? If so, what fuel treatment is good to add to the 87 octane fuel I currently use? I only ride my bike maybe 2 to 3 hours a week. Sometimes it sits for a couple of weeks at a time not being rode. I just want to make sure the fuel doesn't have the opportunity to start clogging my carbs. I don't mind paying a little extra for the non ethanol gas since a full tank usually last me over a month.

Thanks for any advice!

90 (R+M)/2 octane will not hurt your engine. I put no-alcohol premium in my motorcycles if I expect them to not be ridden for a while.

Here's site to find local non-ethanol petrol. Note that Sunoco S100 is no longer ethanol-free, contains 9.5%. Many of those sites have been removed, but many remain. Some have comments about it not being ethanol-free. Damn corn-lobby... I'll buy and eat more corn darnit!! Just leave it out of my petrol!

I also pour a bit of fuel stabilizer if I expect not to ride it for more than a month.
