Now available from JGY, Motul Oils. Motul is one of the best oils on the market and is priced with the consumer in mind. We carry most of the popular viscosities. Motul is Group IV and Group V, which are the only 2 groups that are "synthetic". For example, Mobil1 is Group III, which is a base oil with enough additives to be called synthetic. Group IV and V oils are polymerized base oils. They "outperform in cold cranking performance simulators, have lower volatility and increased oxidation stability. The end result is reduced engine wear, decreased oil consumption and increased oil life."* *DSport Magazine, issue 39
