[QUOTE="Jerry G., post: 1037109, member: 72465"] I have an 07 S.T. and my owners manual says dont use any additives to gas and only use regular gas . I wondered about adding something to keep the injectors clean but because of what I read I have never added anything . I also once read in a publication that a guy added STP injector cleaner and it created some injector problem. In that case I figured his injectors must have been very gummed up and the cleaner loosened it up and then plugged up the tiny spray holes . I have 91,000 on mine and it runs very good and I get the crappy mileage they say I should be getting which is 15 city and about 18 or 19 hwy. After posting this I see I have already posted the same thing LOL but I'll just leave it now . [/QUOTE]
