Cusser FRAM had this "clean drain" system back in the day. I bought one for my RX7 and loved it. I might get one of these for my B2000. People get worried that it'll leak - I never had a leak w/ mine, nor has anyone I've known who also used a similar product reported leaks. I would guess that people have jerry-rigged something up and it leaked, and the rumors started from there. In any case, I like the idea of just being able to change my oil the same way I did w/ my RX7. It was really nice. Never ANY mess - whatsoever.
