hi...Im actually a 2nd gen owner now..but was reading about oil changes ...and something I used to do when changing the oil in my old faithful came to mind. When I undid the oil filter on my 93 with a 3.3 I would wrap a plastic shopping bag around the frame rail....and the stray oil would land on the bag...and run into my waste oil container...rather than into the frame rail..where it would drip all over my driveway for a day
