Hey Guys, Any opinions on running Octane booster in a newly filled tank of 87 (the one time my wife decides to fill the tank[:@])so I can tune it to a 93 without waiting to run out the tank? It is a Black2006 GT, 12000 miles and NEVER seen rain! I just finished with the CAI and exhaust. Now tuning it, but of course INOWhave a full tank and Iwill seldom drive it until betterweather. thoughts on booster and if so which one to run.
TY!

 

Didn't someone on here use an octane booster and it messed up his motor somehow and he tried to cover up that fact when he took it into the Ford dealer for repairs?

 

i used 101 a few years ago and it fouled every plug.i would't do it.just get some racing gas as that won't hurt it.

 

I've heard octane boosters don't work.

 

Octane boosters do more harm than good. A whole can may up your octane 1 point, but definitely will cause problems. To keep your car running best, you'll have to suffer through this tank. Run it as low as you can (when the computer shows 0 miles left, you have 1-2 gallons left) and fill with 93 (or 94 or 95 if you have it available, just to be safe for this tank). Torco fuel additive is the only thing proven safe, and I still wouldn't do that. Take the CAI off, run the tank dry, and start fresh. It sounds like you take care of your car. Don't make the mistake of being impatient and hurting your car.

 

Yep - I've read multiple accounts of octane boosters fouling plugs on these cars. Good luck with that!

 

Pass -- wait for a new tank

 

Do you not have an 87 tune as well? Put that on for now...

 

THANKS!! everyone. I will run it as the 87 tune. (and keep my wife away from it!) LOL, had about 2 gals gas left in it when she filled it.

 

+1 the huge difference is going from stock to tuned. going from 87 to 93 is a very small change. when i did it i barely noticed it. but definately tune that baby up
