Cat 785 service

What each system holds and when Cat says to change it, with genuine filters and oils. The oil grade for your build is in its operator's manual.

  1. Engine oil, with filter
    204 L

    Fluid: Cat DEO-ULS SAE 15W-40 (rated -10 to 50 °C) (Caterpillar Machine Fluids Recommendations SEBU6250-30 (Dec 2020))

    The engine runs near full load for most of every cycle; in Gulf heat the oil works harder, so take an S·O·S sample at every change and keep to the hours.

Confirm fluid grades in your machine's operator's manual: they vary by build year and climate.
