Has anyone tried racing fuel? I can get 100 octane.

Most 'race gas' is just cheapo gas with tetra-ethyl lead additive. Catalyst, O2 sensors, and warranty go bye-bye.
Strictly for cars that have the feedback computer removed, if you still need the closed-loop feedback system, stay away!

Ike the WRX guy says he has seen unleaded 100, that would be relatively safe to use, but you probably won't see ANY improvement unless you change spark timing.

for what purpose would you use it, stickyshift?

 

Local racetrak/sunoco carries "race fuel" it's 100 octane unleaded. $4.99 gallon. There's no point in running it though.. unless you have a crazy FI setup.

 

oh dont make it easy for him lets hear his reasoning to use it and then give him the information he needs to draw an informed conclusion.
