    Fuel Injection Cleaning?

    On my 92 deville, i have 90k on it, and it runs fine to me, is the kind of fuel injection cleaning the garage offers really worth it? Or am i ok just putting some cleaner in the tank every now and then?

    If it runs okay, leave it alone.

    Dumping a bottle of Lucas fuel cleaner into your gas tank with every oil change doesn't hurt anything and it makes a noticeable difference to me

    You could also add a full can of SEAFOAM to a full tank of gas every now and then.Some people add a full can of seafoam when you get down to a 1/4 tank for maximum cleaning of fuel injectors.
