CASTROL MANUAL EP 80W-90

Designed for consistent performance across a wide temperature range, Castrol Manual EP 80W-90 is a mineral-based fluid suitable for use in applications where API GL-4 performance is required. With high thermal stability, this manual transmission fluid stays effective for longer and is the perfect option to maximise performance.


Castrol Manual EP 80w-90 maintains film strength under load while resisting oxidation and wear over time, to deliver extended intervals of reliable performance and protect against deposit formation. It offers smooth gear engagement and helps reduce shift noise, particularly in colder operating environments. This makes it suitable for a wide range of light commercial vehicles and passenger cars with manual transmissions that call for this viscosity and performance profile, and it is approved for use in ZF manual transmissions.
