I am old enough to remember that commercial.
I also believe in preventive maintenance ... or what ever it is called now ... but I also believe in realistic maintenance. At least for this hobbyist the compressor is not used anywhere near like the Navy might use one.
Given that my dad never changed the oil in the used compressor he bought and the neighbor never changed it when he bought it from my mom, the 40+ years of occasional use with what ever was in the crankcase it suggests 'you sometimes get lucky'.
I will assume that most hobbyist based compressors are like mine and don't have an hour meter on the compressor. Therefore I have no way of knowing how much time it would actually have on it between changes. Nor would have any knowledge of many hours it might have run during any given calendar time period. Therefore 'knowledge based predictive' is not an option. If 'knowledge based' is not realistic then the random 'I have some oil on hand and feel like changing it' seems to be the other alternative ... or not.
