What is most popular fuel for FI engines in Stock?
Having tough time finding Unleaded.

I have found the best fuel that is NHRA legal is VP c-11.I have tried c-9 ,didn't run any better and cost more. Not sure why you want unleaded.C-11 is about 3 hun.faster than c-12 or sunoco 110.

C11 or Renegade R11
I'm sure our car would run just fine on the super unleaded that's not cut with methanol. Too bad it's not on the list

I was told to drain any remaining C-11...

My engine, on the dyno, showed 1% increase, in HP, using C11
vs VP110 or Sunoco standard.

I have run all the legal unleaded fuels in my car C9,C10, currently running sunoco 260 gtx. if all you are looking for is et there are better places to find it work on your tune. Leaded fuels kill o2 sensors and you never know how long they will last they will cause you time and money or rounds figuring it out cause it always happens at a bad time. My car is no rocket ship but can put it close to the top of the Q sheet. The one problem with these fuels is the availability of them, not the easiest to find some times, i buy it by they barrel. price can be all over the place, last barrel i bought was under 600. i have never had a problem passing fuel check, except when NHRA removed C9 from the appoved list without any notice, that was a bad morning at the first race of the year.
