  • Expert Hi,

    Castrol CRB is for commercial vehicles like trucks , buses . The 10W-40 .oil is a good choice for controlling engine wear and preventing oil breakdown from oxidation.

    20W-40 Provides maximum protection for high-performance, high-RPM racing engines. Excellent choice for high temperature and heavy loads such as driving in the desert or towing a trailer at high speeds for long periods of time.

    It is always advisable to use the engine oil recomended by manufacturer mentioned in owners manual.

  • Dear friend,
    20w-40 is a thick oil with compare to 10w-40
    according to the science thinner liquids flows quickly as compare to thicker ones.
    the commercial vehicles have all big engine parts as compare to light motor vehicles, which has very fine gaps in engine moving parts so the 10w-40 circulates more faster & easier.
