Can i mix fuel cleaner and octane boost? Or will it damage anything?

Octane boost has small amount of fuel cleaner in it. Use 1st, wait at least 60-90 before adding the other. Pending miles on vehicle, driving habits, along with realistic expectations/results with using product(s); may be 💰👌 or 💸💸💸💸.

Why does it say "for off road use only" on the back under directions ?

2 reasons. 1 so the goverment doesnt pull your car into a smog testing area and you fail the test. 2 so you dont blaim it on k&n when you fail said test.

How much does it increase the octane?

Talking to a mechanic, he said that most gasoline octane boost additives (unless specifically stated) increase the octane rating somewhere between 3 or 4 points.
