Don't change my oil anymore cause I'm old and it's against condo rules, but I did in the eighties. Had a Colt Vista (may have had both Dodge and Plymouth badges on the same car, real quality control on the docks), anyway I couldn't easily get at filter so I took it in to VIOC when they first opened the store. Had me wait in the car while some some supervisor barked orders at the peon down in the pit. "Loosen drain nut" "Drain nut loosened" "Release drain nut" "Drain nut released" "Loosen filter" "5$@#&^*(^&(*B3gDFTH$#@DD0" Remember calling out the window, "So you guys had trouble too." Took cars back a few years ago, not often, because others had oil changes. No problems IIRC.
