100 Octane

[///M3///M5]

Is it completely ok to run 100 octane on our cars? I have read in some places that it may damage O2 sensors. Is this true? All of the gas stations around my house have 100 octane and i have always wanted to try it out. I heard it will make the throttle responce much better, and will make the car run much smoother.

Unless it's leaded you'll be fine.

The 100 won't do anything that the 91 can't unless you've made changes to your car that call for increased octane. If your car is not pulling back its timing because of detonation, save your money.

I've tried the 100 octane gas, the car does runs smoother. I've heard the same thing, you may damage the o2 sensors/fuel filters or would need to replace them sooner than usual, not quite sure but it's better safe than sorry.
