Castrol CRB Turbomax 15W-40 CH-4 is an advanced heavy duty diesel engine oil. It is suitable for use in high speed 4- stroke diesel engines that use a broad range of fuel qualities.
New Castrol CRB Turbomax 15W-40 CH-4 contains specially engineered DuraShieldTM Boosters that help fight the main causes of engine damage. In severe testing, Castrol CRB Turbomax with DuraShieldTM boosters delivers up to twice the engine life*.
CRB Turbomax with DuraShieldTM boosters is proven in industry testing to help provide protection to your engine in two ways:
- Under severe engine operating conditions soot can agglomerate to form large particles which help to displace oil on moving metal surfaces. This results in metal to metal contact. CRB Turbomax with DuraShieldTM boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear.
- CRB Turbomax with DuraShieldTM boosters provides a protective layer on the moving metal surfaces which resists break down, even under difficult conditions.
* Based on time between camshaft rebuilds in a severe Cummins ISB engine test vs. an equivalent oil without DuraShield.
