My Camaro doesn't "ping or knock" using the lower octane, So, my question is, is the higher octane really necessary?  |
This is a great question OP, excuse the knuckleheads who only want to talk money in this thread cause they have no real experience or knowledge to add.
Other than lower performance and possibly lower mpg, will running the lower-test fuel damage the engine or cause any parts to wear out quicker? Carbon build up?
