Can I use Rislone Engine Oil Supplement with Zinc Treatment in my newer vehicle?
No, you should not use Engine Oil Supplement with Zinc Treatment in 2005 and newer gasoline and 2007
and later diesel engines. Current oils have enough Zinc to protect moving parts inside newer engines.
However, to help prevent sludge and keep that engine clean, it is recommended to use Rislone Engine
Treatment p/n 100QR or 4102 on all newer engines.
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.
How can the Rislone Engine Oil Supplement with Zinc Treatment help prevent dry starts?
Rislone Engine Oil Supplement with Zinc Treatment contains copolymer esters (Tackifier) that have an
affinity (attraction) for metal surfaces. This allows the oil to hold onto the metal surface instead of just
running off like normal motor oil does over time. This along with the ZDDP creates a double layer of
protection.
Will it work in synthetic oil?
Yes, Rislone works with all petroleum-based motor oils including conventional, high mileage and synthetic
formulas.
