MAXXLUBZ WILLIAM 15W-30 is a premium and innovative diesel engine oil intended for engines that have duty cycles that qualify as “severe duty.” These include reducing idling time by turning the engine off at stops or deliveries, stop and go in heavy traffic or city delivery, or situations where engine cooling may be stressed like when towing heavy loads or when cycling between fully loaded and unloaded in off-road applications.

MAXXLUBZ WILLIAM 15W-40 is a mixed fleet motor oil recommended for naturally aspirated and turbocharged four-stroke diesel engines and four-stroke gasoline engines in which the API CJ-4 service category and 15W-40 viscosity grade are recommended.
