it's your bus, but i think it's a worthwhile investment to install a pair of $12.00 oil filters while your going through the trouble of changing the oil, or are you using some sort of special super filter ??
Quis custodiet ipsos custodes (who will watch the watchmen?)
No super filter but we only put a couple of thousand miles on the bus every year, so the oil is due mostly because of age, not really miles.
Mostly we're in a time crunch right now. If I can squeeze it in, I'll do the filters as well. Thanks for the prodding.
