fuel injection cleaner,octane booster etc, is it worth it? Options

[daazndood]

hey guys. i was roaming autozone the other day. i ran across things such as fuel injection cleaner, octane boosters, and stuff that supposed to clean your intake and carb and stuff like that. all of them would be dispensed through the gas hole.

im just wondering if these things really work? they are labeled as lasting for 3,000 miles which would mean i would only use 2 bottles a year. thats like 10 dollars a year which isnt bad if these things actually do something.

anyone have experiance with them?

Fuel injector cleaners work IF you have gummed up/clogged injectors, that said, I run some through every few tanks to keep from getting there. Seafoam is good, Chevron Techron is good, as is the Amsoil PI and Amsoil PowerFoam I use.

True octane boosters work, the Celicas just cant make much use of them. You need an octane booster to increase the fuels resistance to burning so you can run higher compression and advanced timing while reducing the risk of pre-ignition and detonation. If you have not modified your motors compression or timing, I wouldn't waste your money. I will however continue to run premium in my GT as that is what it recommends in the owners manual for "best performance"
