Fuel injector additive
 

My 95 325i conv was acquired with 127K miles - runs well. Would appreciate knowing if the injector cleaner added to a tank of gas is worth doing & if so how often.
Thanks

It's my understanding that injector cleaner can be helpful, but don't go overboard with it. In a properly maintained engine, it should only be used about 3 or 4 times a year, at the change of the seasons being a good interval.
