The Sunoco 260gtx is an unleaded fuel, similar to VP C-10, easier on the A/F wideband sensors esp for the late model and dual duty street/strip use cars, although most guys on here will use the leaded fuels (C-11, C12) etc. to extend valve train life and achieve higher octane ratings. Another issue is availability, a racers preferred fuel may not be sold at certain tracks... Thanks to MG raceway for posting this chart.. http://www.maplegroveraceway.com/wp-...-reference.pdf

I can find it and less expensive than C10. RKelliher said that running C11 works better than C12. How does is work that one Octane Fuel works better than another? Dan |

Consistently, on a dyno, my engine makes 1% more HP with C11,
compared to VP110 or Sunoco Standard. Terry K |

We also are faster with C11 than C12 in back to back testing
in our low compression Stockers!

Most popular fuel is probably C11 in stock across the boards. That or c12.

C-11 makes the most power with my combo (dish 305). Tried them all!
