Description

The Royal Purple 83561 is a 1-gallon container of Duralec Ultra synthetic diesel motor oil with a 15W-40 viscosity. It is formulated to maximize performance and meet the demands of heavy-duty engines.

This oil features Royal Purple's Synerlec additive technology, which creates an ionic bond with metal surfaces for protection upon startup and increased film strength to prevent metal-to-metal contact. It offers superior corrosion protection, a low coefficient of friction for optimized fuel efficiency, and better wear protection.
