For my 2006 should I go with an fs2500 filterion or ansoil system

 

You might also consider the MotorGuard or Frantz TP bypass oil filters. They work very well!!!

 

I have the OilGuard Bypass system on my truck. I was suprised at the size on the filter housing, it's huge! I had to mount it on the frame below the passenger door. Other than drilling the holes in the frame (you need to use short drill bits or a right angle drill) it was a pretty easy install.

 

where are you guys installing the return line?

 

I have the Oilguard system also. The return line goes in to a new oil filler cap that comes with the kit. Very nice kit. I would recomend it over the FS2500 because nether one will keep a Cummins oil honey colored and the Oilguard system is much cheaper in cost.

 

I vote for the Oilguard as well. Super nice, well thought out system that seems to do the job well. I've had mine for a little over 4 months now.

 

I already have an amsoil system I haven't hooked up, I wonder where or if I could just get one of those oil fill caps??

 

Not trying to be a smart*** here, but what are advantages to oil bypass? Is it because it filters twice? But if some or several of the cummins have gone several hundred thousand miles with stock filters, what is advantage? Longer oil intervals? Thanks

 

i have had a oilguard system on my truck for over three years, i usually go over 10,000 miles between oil changes. the oil guard filter gets changed every other oil change..... by the way, i have used delo 400 15-40 from day one, no problems other than some minor oil leaks

 

Thanks John, sounds good. Delo is good oil.

 

Oilguard here too.... and Motorguard... Overkill is my middle name...

 

NELROD,

Where the stock, fullflow filter may filter down to 15 microns, or so, the Bypass Filter filters down to 1 or 2 microns, usually.

Some "toilet paper" filters have the ability to filter into the sub-micronic range (Gulfcoast, Motorguard, Frantz etc.). The downside to these filters is that you need to change them out, more often. Possibly every 2000-3000 miles. The filters are very cheap (roll of toilet paper) but, you have to add "make-up oil" to replace the oil you lost in the filter change.

With some of the other brands, the filters last much longer but, are more expensive than toilet paper. And, you don't have to replace as much make-up oil. If you are using a synthetic oil, that can get a bit expensive.

You are right about these engines lasting a long time without bypass filtration. Some have made it substantially longer than a million miles using conventional oil & stock fullflow filters along with normal oil change intervals.

Bypass filtration is not necessary but, if you love your engine & want that "warm & fuzzy feeling" that comes from knowing that you are giving your engine the very best treatment possible, then you may want to resort to the extra filtration.

From the reading that I've done, the best "bang for your buck" with bypass filtration comes if you use your truck commercially, as in towing travel trailers from the manufacturers to the distributors. Basically, putting an enormous number of miles on your vehicle. Running a fully synthetic motor oil along with a bypass filter will allow you to extend your oil drain intervals rather dramatically. Especially if you use "used oil analysis" to guide you in your oil change intervals.

This will save you the inconvenience of having to stop & change the oil, so often.

If you would like to learn more about Bypass Filtration, you may wish to go to "bob is the oil guy.com" & check out the "Bypass Filter" forum. Lots of, lubrication related, information there.

Thanks a lot Buffalo, that is good info, and that is a cool site too (BobOilBuy)
