Finally, a motor oil that's one for the classics...

Today's engines face different demands than those of yesteryear. Now classic car owners who are particular about what they put in their vintage vehicles can receive modern wear protection from a high–zinc formula specially engineered for classic engines.

Back in 1906 Castrol created its first automobile lubricant. Since then, our leading–edge technologies have protected generation after generation of engines. Castrol SYNTEC 20W–50 motor oil is geared to protecting, preserving and helping extend the life of your vehicle from an age gone by that still lives on.

Key Benefits *
