Cat 323 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 (Cat grade for -10 to 50 °C) (Cat 320, 323 Excavator Operation and Maintenance Manual M0068104-12)
Filter and ground-level dipstick are behind the right side access door; filler and upper dipstick under the engine service door on top.
Oil carries soot and heat out of the C7.1; dust and summer heat age it fast, so change it on the hour and keep up the S·O·S samples the longer interval depends on.
Confirm fluid grades in your machine's operator's manual: they vary by build year and climate.
