Oil and Tranny Bypass Filters- Discussion

[Ross-N-Chicago]

Guys & Gals,

I know the (probable) answer to the question already, but why is it that there is so little talk in the conventional world about bypass filters? I know the rub for auto industry would be longer lasting cars, less maintenance and production so less profit$ for them. But wouldn't that be great if we had cars that truly lasted to 150-200K miles or more with very little mechanical breakdowns and just an emphasis on maintenance?

Detroit would lose a bundle in service costs, no doubt. And with the rising costs of petroleum, not only as a limited natural resource but also b/c of our dependence on foreign oil, we could seriously get some bang for our buck. From what I have heard, a tranny filter costs about $30-35 and the oil bypass filters (Amsoil is all I know of, I'm sure there's more) run generally $150-200. Now imagine a filtering system that truly and virtually eliminates wear, especially if you ran 0-30 or 5-30 fully synthetic oil!! You oil would and could last 25-30K miles and your engine would have none of the damaging micron debris because the filter system is cleaning the entire amount in the engine every 5-6 minutes at 45mph.

I don't need anyone to try and sell me on the tranny filter. I've read the posts and will be putting one on soon. Great feedback on that, guys. This board sure does its homework.

I would love to hear some feedback from more experienced enthusiasts and mechanics. I am just an accelerated do it yourselfer. I feel I am going to have a hard time being disproved or swayed back to regular oil changes.

I was thinking of putting in a bypass filter on my expo. The only thing is where i'm going to mount it. i can't fit it in the engine compartment and i don't want to run long lines. i never saw the bypass filter for the tranny though. That sounds interesting i might look in to that.

oops. i posted the link for the aux. tranny filter, then read your post in full.

Any thoughts and comments on the ByPass Filtration system?

Most engine and transmission failures are not caused by dirty lubricants. when I was a claims adjuster for GMAC I never had an engine or transmission failure traced too poor filtration except in a few cases of neglect ( eg-never has an oil change in 40k miles). The stock filters work fine. That being said, better filtration should make your engine last longer. However, other things going wrong with your vehicle will make you want to get rid of it before it dies from poor filtration.

But I wonder if dirty oil was a predisposing factor in failures traced to mechanical woos?

Not that could be seen other than neglect. For example, if a bearing fails and is scored, but the others are perfect,we would assume it was a bad bearing and not dirty oil. However, A trans failure was suspected to be caused by a clogged filter that dropped pump pressure. Again, this was a case of neglect and the problems were believed to be caused by insufficient pressure, not dirty fluid. Even with an auxilliary trans filter I would still change the pan filter every once in a while. You wouln't believe the people with high mileage cars that had the original factory oil filter on it! This is testimony in itself as to just how good modern lubricants are.

Thanks my literate friend.
