My car is a VW turbo so I'm fearful of not changing the oil filter. The VW engineers would probably be horrified at my treating their car this way. They are very particular and peculiar people. The say absolutely no regular clamps on the vacuum lines! I have no idea what would happen if I did. I'm guessing that the headliner would fall and the doors would refuse to open - at least that's what's happening with my Passat. Hee hee.
