[Yella GT]

I now have access to race gas at the pump.
101 Octane unleded $5.22
111 Octane leaded at $6.12

The car is a 94 GT with mild mods (headers, ignition @ +12, BBK 70mm, CAI, off road X pipes and flowmasters.)

The 101 should be fine to run. what about the 111 with lead for the track (road course). Any impact on the injectors? Other concerns?

I am also looking into a multi tune pack and I ahve access to a dyno.

ANYONE with ACTUAL experience using these fuels?

leaded fuel will Kill Oxygen Sensors....
now, you can use the leaded fuel, just as long as you dont mind replacing O2's every other week or-so.....

remember, you ONLY need enuff octane to prevent detonation, using a higher octane level then whats needed to stop detonation can actually rob HP & TQ

well i tryed about 1/8th of a tank of cam2 racing fuel. its leaded, was pumping it right into my car till the owner came out and told me he can get charged a 200,000 dollar fine. then he told me about the O2 and the cats i have. so still curious about the preformance i went out to a trucking road and a break stand. it got the left wheel spinning for a change. didnt have enought cam2 to do another tho. went straight to the pump again got my self so STP complete fuel system cleaner and filled the tank. ... ... been clean sense. lol
