I think the same machine oil you use for CNC will work, but I use sewing machine oil to lube the X and Y rods (couple drops) whenever they feel "dry" to the back of my finger:

For Z-axis, I use PTFE synthetic grease (drops all along the Z axis) like this every... 6 months?:

Also, make sure the extruder gears aren't grinding/biting into the filament too much and getting filament poo poo buildup all over the gears.
Spare nozzle, hotend, thermistor (I've only had to replace a hotend once in 2 years and also because I made a dumb mistake).
Don't be afraid to ask for help when you aren't sure because if you screw up, you may damage your printer.
Sewing machine oil is a great light oil that gets down inside the chain like WD-40 but does not contain solvents and its cheap.
