I have a '93 RX7. Eventually I plan on having no cat on it. (with the propers additional mods to keep it from blowing of course)



Is lead aviation fuel ok for rotary engines? I assume it is but I just want to check.

Yeah, it's ok, but you may mess up non-heated O2 sensors. I told my friend about it, and he uses it alot now. It's pretty cheap too, 100 octane.

No long term effects??

The lead can foul O2 sensors, especially non-heated sensors.

Back in the summer I think it was less than $2/gallon.

Can you just go to an airport and buy this stuff?

I would try a small local airport.

You cannot by federal law pump any leaded fuel into a motor vehicle.

You can only buy it and have them put it into gas cans.



You mayyyyy find a super cool guy who works there who might let it slide, but I doubt he will risk a felony to give you some gas, lol.

is this for 2nd gens also???
