What do you guys with high compression motors use for fuel? Leaded? Unleaded? Octane rating?

With my street (gpz) bike which is 10.5:1 I can only get 91 in my area. So I put a pint of Sunoco 112 blue supreme in every full tank.

I guess I should be more clear. Back in the day I would try getting Sunoco 94 and my 1105 10.5:1 wouldn't ping. If I used 93 it would ping sometimes.

What would be safe to use for a 13.5:1 motor? Can leaded fuel be used or should unleaded fuel only be used??

C12 is what I plan on running in my 900 when I finally get it built and running.

VP110 leaded. It also is very stable over the off season and doesn't break down like pump swill does.

They sell "Turbo Blue" at a racetrack close to me....they have their own pump at $7.99 per gallon..... :sick:


The octane is 112..... ;)


You can really tell the diff in throttle response and the bike pepped up, but for the money.....I will stay with 93 at $3.22 per gallon as of today.
