Join the Evolution with the new RX Super

Castrol’s upgraded RX Super to CJ-4. RX Super with DuraShield™ Boosters deliver up to 40% better wear protection. DuraShield™ Boosters actively work in two ways: fights soot agglomeration and provides a robust protective layer on critical moving engine parts.

DURASHIELD™ BOOSTERS

DuraShield™ Boosters are new technology, exclusive to Castrol. They’ve been specially engineered to fight wear, deposits and corrosion, the main causes of engine damage, to deliver superior protection in 3 ways.
