How is Rislone Engine Oil Supplement with Zinc Treatment different than break in additives?
Break in additives contain extremely high concentrations of ZDDP and are only designed to be left in the engine for a short period of time. Many of these additives don’t contain detergents or other lubricity additives important to keeping your engine clean and lubricated for thousands of miles. Rislone Engine Oil Supplement with Zinc Treatment not only contains the correct amount of ZDDP, but also the other additives important to protecting your engine. Do not use as a break in additive.
