View Full Version : Octane question

I was just wondering if there is a limit on the octane you can put in your GN. Reason is i found a gas station that sells 108 and i would like to try if it wont damage the engine.

No. But if it is leaded fuel, it will damage the catalytic converter...if you have one. And leaded fuel on the street is also illegal, of course. :brows: The cost may also damage your wallet.

Nope. Just the air and ground water. :shock:

leaded fuel will also kill the O2 sensor very quickly.

...but less quickly if its a heated one, and allowed to heat a bit before starting the car.
