Octane Boost

[Showtime]

Does anyone use any kind of additive to their engine? Like Octane boost,,injector cleaner etc?

I heard it wasn't a good idea to do.

I throw in a bottle of STP Injector Cleaner quarterly before filling the tank. Have done so with my previous 3 Thunderbirds and still do in the F-150 w/no problems to report. :CHEERS:

I use chevron injector cleaner every time I change the oil. I have done so in my last 3 mustangs without problems.

some cleaner now and then sounds good to me..octane booster is hard on plugs and does very very little anyhow
