I am not a believer in oil additives. if you service your regularly, there is no need for these. Oils have all the additives you need already installed.

Sea foam helps clean injectors and oil sludge but going back to servcing, if it is serviced on a constant basis, no need for this.

Based on experience I have seen additives causing more harm than good.

However in cases whereby you are trying to coax a little more lifespan out of a failing engine they might help a little. Other then that, it is a waste of money.
