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.
