From what I read here. Some think bypass filters are a waste of time. I guess if you drive a new car and trade it in every few years. The economy has people keeping cars longer. I see nothing wrong with trying to keep stuff out of the oil that would cause wear. I think regular filters are only so good. So the more filtering the better. Unless your lazy or just don't care. I even think filtering fuel wouldn't be a bad idea either. I read up on Dodge Caravans. I have one and people complain about the transmission, a lot. On the Allpar site it has an article about stuff getting in the little filters in the transmission pack. So who knows what kind of problems could be solved with a little bit better filtering.
