Friend of mine has access to it, he says its not AVGAS but racing fuel? I thought it was the same thing... Anyway, I'm running an APR chip with stock KO3s and Neuspeed exhaust as my only mods.

Ummm... that's probably leaded gas!!! Good bye CATS + O2's! :-O

WesS4

I'll take a pass on that then, haha.

Who has cats?

leaded gas isnt going to kill off your O2's with just one use...more like by one hundred times used

I've known people who blew their 02's by running that gas fella.

ErikS4

be fine.

SoSlow

the point is, leaded gas will foul O2 sensors in the long run, not from just a few uses..

safe (unless you spill it on your paint). MMO = Marvel Mystery Oil. I have run such a mix for years without so much as a CEL being triggered. It cleans out the injectors as a side bonus. Might be slightly more expensive, but it is perfectly safe (unlike leaded gasoline).

You could always buy VP104. I've run 100 octane unleaded and i get +10 degrees of timing! )
