Oil additives should never be added to a new engine. The slippery compounds that make up these oils, prevent the wear-in of the parts together. You may have an increase in oil consumption because the piston rings cannot seat or seal properly with the piston cylinder. I would wait at least one year or 12,000 miles before using such product on your engine. On the contrary, if you have an older vehicle, oil additives are great for your vehicle. It helps maintaining the engine on a cold morning startup. If you need further assistance, do not hesitate to contact us.
