This oil is made from high-quality synthetic base oils and contains a carefully selected additive package. These additives provide excellent anti-wear protection, oxidation inhibition, and corrosion protection. The oil also contains detergents that help to keep the engine clean and free of deposits, ensuring that the engine runs smoothly and efficiently.

The Continental 639304 TCM Vernatherm VD-21038 is compatible with most two-stroke, air-cooled Contental and Lycoming aircraft engines, including those with aluminum pistons. It is important to note that this oil should not be used in four-stroke engines or in engines that require a different type of oil.

When using this oil, it is recommended to change it at regular intervals as specified by the engine manufacturer's maintenance manual. This will help to ensure that the engine is always protected and running at its best, and will help to prolong the life of the engine.

In summary, the Continental 639304 TCM Vernatherm VD-21038 is a high-performance aviation engine oil specifically designed for two-stroke, air-cooled Contental and Lycoming aircraft engines. Its unique Vernatherm technology provides superior engine start-up and protection, while its multi-grade viscosity range ensures that the oil flows freely in all temperatures. With its excellent anti-wear, oxidation inhibition, corrosion protection, and detergent properties, this oil is an essential component of maintaining the health and longevity of your aircraft engine.
