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. Castrol CRB Turbomax with DuraShieldTM boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear.
Castrol 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. a conventional CH-4 engine oil without DuraShield TM.
