I really hate to start this debate, but was recently discussing on a forum for the last car (gt ford probe) - I know, I know, the only car with a crappier trans than the 4l65e.
Anyway, for all 13 yrs I had that car, everyone ragged on the fram filters. Crappy anti drain back valve, crappy construction, etc. For the entire time I abused the hell out of that car (also 13 yrs), I used dealer filters and the engine was perfect when I sold it a couple months ago.
I sort of forgot about this when I got the GP (base) and I am curious if you guys have the same thoughts. I've used the fram synthetic filter on the GP. Are they really that bad? If yes, recommendations? I get the impression that most of you people are just as crazy about maintenance as I am
