Cat 420 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.
Loading the 3D machine...

- Engine oil, with filter
- 9 L
- Engine oil and filter, change every
- 500 hours
Fluid: Cat DEO-ULS SAE 15W-40 (Cat's grade for -10 to 50 °C) (Cat fluid selector: 420 (S/N H8T00001-Up))
The C3.6 holds only about 9 L, so a missed check or a late change on a hot day costs it quickly; the dipstick and filler are under the top engine door.
Confirm fluid grades in your machine's operator's manual: they vary by build year and climate.
