I‘ve been told to put in something like Lucas Oil Stabilizer or one of the store brands. Is this necessary or a waste of time.
If your car is newer you do not need an oil additive. Older cars with high mileage Id recommend Castrol GTX High Mileage. Your car should need no additives at all. If your motor is loud,,i.e. lifters tapping,, putting an additive in it only covers the problem. Eventually it could cause more problems.
oil has all the additives you need for your engine. It is unnecessary. You would be fine without it.
