Cat 12M 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.

Fluid: Cat DEO-ULS SAE 15W-40 (rated -10 to 50 °C) (Caterpillar Machine Fluids Recommendations SEBU6250-30 (Dec 2020))
Cat groups the daily service points on the left-hand side of the machine.
The engine sits right behind the cab in the heat of its enclosure; Gulf heat and blade dust age the oil fastest, so do not stretch the change.
Confirm fluid grades in your machine's operator's manual: they vary by build year and climate.
