Here is a random question....


Do people use fuel additives like injector cleaner etc? Reason why i asked as i thought they were pointless and can make the car run like a bag of shite etc

But recently i saw a bloke at my local halfords in an Evo 8 purring what looked like STP Injector cleaner into his fuel tank....Now this got me thinking....Do they actually work? I went to French Car Show awhile back and got some free STP Injector cleaner and never thought about using it but i am thinking i might? Lol
