100% synthetic ultra high performance racing oil. Considered by many to be the best in the world, Motul 300v is one of very few motor oils that utilize Ester base stock in their formulation. Ester is more expensive, but is unmatched in performance and engine protection. The ESTER Core forms an ionic bond with the metal inside your engine, so it adheres better than standard synthetics to ensure you never lose protection between startups, even when the engine has been off for extended periods of time. Will not break down in high stress, high temperature use, and has enough detergents to be used daily on the street. Add in Motul's decades of research and experience in top motor racing worldwide, and you get the ultimate additive package blend, resulting in the absolute best motor oil money can buy.
