re: Oil change shop air filter up charge….WTF

believe it or not, the prices jiffy lube places charge for an oil change is artificially low. The make them low so they can get you in a make their profits on other things. No business could sustain itself on oil changes alone. My advice would be to avoid these places and either pay your normal mechanic his shop rate to do it or change it yourself. The people that work at these places aren't someone you want touching your car for any reason anyway.
