Hello, I would like to add a fuel injector cleaner to my Lincoln. Would you give the go-ahead to Castle Injector Sting? Also gasoline is required at 92 octane. Will it harm the engine if I use 89 since the price of gas is rising fast again. Thanks, Mauro
Just bought this car - nice site :-)
have the same problem?
