First car was a 65 Corvair Monza. Was able to get AC Delco filters at the corner gas station for it. Back then you could get an oil change for the cost of oil and filter alone (no labor charge). Most Sears, Wards, and Penney's had auto service facilities back then. They were also the cheapest places to buy oil and filters for do it your selfers but you really didn't save any money doing so.
