I've been doing a lot of reading about Bypass Oil Filters and they seem like a very good idea in our dirty 6.2's. Has anyone installed one in their 6.2? I did a search and didn't see anything.
If anyone has installed one, what model did you install? How much did it run you? And have you noticed any benefits besides cleaner oil? (better mileage, cooler temps, etc)

I have been wondering about that too. I have been eyeing the Amsoil kit BMK-11 for quite a while, eventually I will probably take the plunge and get one. If you go to the site www.bobistheoilguy.com you can find out almost anything you want to know about oil and filtration. There is also a forum there about bypass filters.

I will check out that site for sure.

I figured among this gaggle of non-gas running nuts, that someone had to have already tried it, and being the lazy slug that I am, hoped to leech off of someone else's experience.

I have one on my 6.5. Can't vouch for cooler temps or better mileage (I do avg. about 19mpg), but I run my oil longer. I send in a sample and still change the regular filter every 6k - 7k and the bypass filter yearly.

I'm already pulling right around 20 with my Jimmy, I'd like to get it up to about 25. Of course, I want more power too...it's not fair. More power should equal better mileage.

actually, I just want to make it more efficient. Someday I'll get a turbo.

HOw hard was it to plumb in? Where did you mount it? What brand are you running?

Dr. Lee did it and the articles are around. He also found a cost effective way to do it.

Are they still current, or do I have to look into "the archives"?

Got one on my '83 and purchased it from Greg Landyrt - TDP sponsor http://www.lubricationspecialist.com/. I can't tell a visible difference as new oil will turn black as soon as the engine starts up. I feel good about the tests I read about and know it is filtering the oil better. I have mine mounted on the frame right under the driver's seat (outside, of course). I just sent off a sample to be tested with 15k miles! We'll see what they say.

I have the Amsoil Dual Bypass system. The system comes with a hose kit, but when I replaced my engine, I had new hydraulic lines made at the local Bumper to Bumper store, and bought the fitting I needed. Any hydraulic shop can make up the hoses, if you know what fittings you need. The fittings were the most expensive part. I had a local tractor suppy house order them for me. It is easy to install, the hardest part of the install is getting the fitting tight at the filter adapter and making sure the hoses do not touch the exhaust. I put a plastic cover, (wiring loom), over the hoses to protect them from rubbing and maybe a little heat (??). I mounted the fixture on the left inner fender in the engine compartment. I made my own bracket.

I have the Dr Lee setup and it works great it uses a Donaldson P551550 filter. I have the Dr Lee setup on two diesel rigs. I just got a Frantz (http://www.wefilterit.com/) bypass filter that uses toilet paper for the element. I have not mounted it yet through, so I don't know how it works.

I have the frantz on a chevy and had one on my dodge. They seem to plug up in about 3-400 miles on older and overfuelled engines. I use my Dodge on long trips so I switched to a Oilguard system, seems to be working well, at 400 miles. On both systems they keep the oil clean enough to where I can read the markings on the dipstick untill they plug up. Getting rid of the tp filter is the hardest part for me. I clamp it with about 15000 lbs pressure for a few days to get most of the oil out. and then save it for winter and burn in my trash burner.

Topmech, I have been debating about the oil guard system/filter. Sounds like a good system. Had a Franz filter on a diesel rabbit, it did not clog up. Are you using WVO in the vehicle that clogs at 400 miles?
