My wifes runner has 50K on it, and has had Amsoil in it for 22K. I wanted to get a bypass on and figured this years oil change was the time. So I ordered Amsoil's BMK-13 Dual Remote Oil Filtration Kit. This kit remote mounts the full-flow filter and adds a bypass filter as well. The full flow filters 98.7% at 15 microns (most full flows are 30-40 microns), and the bypass filters 98.7% at 2 microns, wear is cauesd by particles 5 microns and larger. This setup will safely allow my to go 1 year or 25K on on oil change, 1 full flow filter, and 1 bypass filter. And after one year the oil will still look clean...

The only place i could find to mount the setup is on behind the front bumper. Since the metal part of the bumper is a square tube I couldnt bolt something to it, and wanted something stronger than self taping screws so I had a plate welded to the bumper.


I then cleaned it up and painted it. I mounted the bracket high enough that the bypass filter is above the bottom of the bumper by about an inch.


This adapter screws on in place of the filter. It then gets high pressure JIC fittings for the hoses that run to the remote mount.


This is the filter side of the mount. You can see the pressure regulator that limits flow to the bypass.


Mount is mounted


Hoses run, with enough slack to allow motor movement. I do need to get some rubber hose it wrap around the hoses in a few places to prevent chaffage.



The filters. The bypass is about 4" wide and 6" tall. The remote mount uses the same thread pattern and gasket size as OEM but I with a much larger filter because I have the room. This particular filter is a ford filter, Fram 8 equiv. Both filters have anti-siphon valves so I am covered there. Thou with the filters below the oil pan they wont drain, thank goodness I only have to change the filters annually as it will be messy.


Filter installed. I prefilled the filters, and it took about 1.5 quarts to fill them. My total capacity is now about 7.5 quarts vs 5.5 quarts. The added oil will run cooler, as well as the filters being cooled as I drive.


And the clearance the bypass has above the bumper. If I wheeled this truck I would probably make a skid plate, but its the hwy rig so I am not worried. I will thou carry a cheap OEM size filter with me in case something happens to puncture a filter so I can go back to OEM if I have to.


I have this same setup for my taco, but haven't installed it yet.

Have you ever had a used oil analysis done to justify the yearly change interval?
Not in years. We used to do them 10 years ago when I was in highschool and it always came back good, even on 100K+ motors. Todays filters are much better than the ones back then, so I am not worried. Just for grins I will probably run an analysis in 6 months, then again in a year... thou I am 100% confident it will be fine as the oil change interval is 25K/1 year w/out a bypass.

Here it is..... The bypass did an amazing job keeping the oil clean... My wife has put just over 8K on this setup in the last year. The only thing I don't like is how low the TBN is, I was hoping to run the oil for another year. Oh well, one change a year isn't so bad. I will change the oil and the full flow, but leave the bypass in place for another year. I doubt I do another oil analysis on the engine, not worth the cost...wear and oil were good, and a year is about all the oil is good for... The TBN is probably so low from frequent short trips... grocery store is .3 from the house, the gym is .5, etc.... and there are only a couple road trips on the oil, most is around town driving at 3K feet, which isn't so easy on oil....

All in all I am very happy with the setup.
