To my knowledge, oil additives are a good idea only if you start using them when you buy a brand new and you are the first person to own the car. It is not a good idea to use them with a car you bought, when you are perhaps the third or fourth owner ; car with high miles, not good idea. The vast majority of oil additives are snake oil products. Leave them alone. Change your oil & filter religiously and do not put any additive in your engine.

Engine oil additives actually reduce the amount of friction that can be very intense and harmful to a engine, especially when starting from cold. Chemical polymers and agents that make up the engine oil additives are designed and engineered to add a level of extra protection to the standard engine oil. However, a good name brand engine oil, installed into your vehicle with proper weight and viscosity and proper oil manufacturer recommended additives -which are already in motor oil from the manufacturer - is all that is needed. No other additives should be used unless the automobile manufacturer has suggested it's use.
