I am looking to do a bypass filter system for my truck in the future. What are some good ones, cheapest and easiest to mount? I don't want to spend alot of money on one but I do want something worth having. I looked at OilGuard and they seemed like a good unit. Anyway, let me know what you guys have and what you paid for them. Also where you bought them at? Sorry for the big list. I plan on running the same oil (Rotella 5W40), but I would like to keep my oil fresher longer. Plus I pull a pretty heavy toy hauler, so I want to protect the engine as best I can. Scotty
 
OilGaurd here... works very well. I use it in conjuction with the FilgerMags, and had a particle count done with the Blackstone Oil analysis. The results were better than any other report I had seen presented here.

I purchased mine on sale for $304 including 3 filters.

JCasper, if you would like to PM me the price I would appreciate it. Thanks for the comments. I am kind of looking towards the AMSOIL and the Oilguard, so if there are others that you have and like, let me know. Scotty

Amsoil on 4 of my trucks. Easy to mount as I fabed a bracket in front of the passenger front tire behind the bumper. I had to cut some of the plastic but now it is easy to access and change and is out of the way.
 
Are you going to do the filter to extend your drain intervals? If not I would think that the bypass is not going to give you the value - I think you would be better off changing your oil more frequently and that would accomplish your goal of protecting your engine; just my . 02 cents.

Somewhat... but you still don't filter out those small particles, the ones that cause most the wear.
 
I didn't install my Amsoil bypass with extended drain intervals in mind. I installed it to catch the smaller particles that DO the most wear damage and shorten the lifespan of the engine.



Dyno oil is cheap, synthetic oil is a little more expensive, but engine work will take your breath away in costs, and a crate engine is like paying for a funeral.

I was under the impression (maybe wrongly so) that with the newer CI-4 oils they did a much better job suspending those smaller particles that cause wear. I agree with the idea of protecting the engine but I just can't justify the cost. In addition I am uncomfortable with adding aftermarket products to the oil system, especially under warranty.

They do suspend it (soot) better... CJ-4 is supposed to do this even better...



However, as those soot particles build up, they can agglomerate and they can get large enough to start increasing wear. If you keep those small particles in check with a filter, they can never get that large. As an added benefit the oil will last longer since its not using its additive package up as fast to suspend those particles.



There are other bypass filters that perform as well as the Amsoil and may suit the buyer better between size, mounting options, initial purchase cost, and overall operating costs.



The cheapest option I've seen is a Baldwin spin-on filter on a Napa filterhead, but this requires researching and sourcing your own parts... IIRC, one guy built his entire bypass setup for under $80 and the replacement filters were around $8/each.

It has been established by many oil Companies as well as Filter Companies, as wel as Engine builders that particles from 5-20 microns are what cause the most wear in internal combustion engines. Most "FULL-FLOW" filters are incapable of removing contaminates less than 40 MICRONS, as a "FULL-FLOW" filter needs to be able to handle extremely high FLOW rates. . This is why "BY-PASS" filters are by-pass filters. Simply stated, they allow finer filtration at a slower flow rate.

A bypass filter will NOT interfere with your factory warranty. Extending the factory recommended drain intervals will unless you can back that up with oil analysis from a credible lab. My Amsoil setups cost me less than $120. For years we ran Purodyne bypass systems and we were very happy with them. They are hard to locate on the Dodge as they are top loaded drop ins. We ran one F800 dump truck with the 8. 3 Cummins 800,000 miles on Delo 400 and never changed the oil. When we sold the truck it was running perfect.
 
Whatever you do do not buy the Amsoil model BMK-25. I have it on my truck and i am going back and forth with the tech. department trying to resolve my issues. It is suppose to be improved from the older model and is actually specified for my year truck, but i bought two of them and installed them on both 2006 trucks and they both have the same problem. If you go Amsoil make sure you get the single not dual kit.

It still has an oil psi issue?? (not a real issue, but an ECM issue). .
