Castrol Classic Valvemaster Plus Fuel Additive with Etha-Guard
Protect and enhance your classic car’s engine with Castrol Classic Valvemaster Plus, the advanced 3-in-1 fuel additive.1 This formula offers the best defense against long-term engine damage while improving performance and mileage.
Ultimate Valve and Ethanol Protection

- Enhanced Performance: Increases acceleration by up to 3%.8
