amsoil bypass filter
 

Does anyone have this setup, looks good and for what i read seems to be good but opinions from people who actually have is the key.
thanks for any feedback.

I allways consider this setup, I am curious to see if anyone has it.

I recently went with the Racor bypass filter on my diesel truck. Same concept as the Amsoil, but with less expensive replacement filters, and they are not screw on type. Don't have the oil analysis yet, but I too am interested, and hope it is not hype.

let me know when you have the oil analyzed, sure curious to see the results.

I've got a used Amsoil dual system for sale with xtra filters.

I liked it fine, ran it on my 01 dodge/cummins, took it off when I traded it and never installed on my 03 cummins due to space issues and extended oil change intervals.

On my 01 I ran amsoil synthetic oil to 60k with good oil analysis, changed at 60 as soot was reaching limits.

The results:

Sorry, that is kind of small to read.

the results on the far right were Dyno oil, samples at an oil change.

Second to the right is Delvac 1 synthetic oil, with no bypass filtration. I took the sample while installing the bypass filter housing and a new full flow motorcraft oil filter, as usual. The high alum content is worrisome, but as I took the sample through the new bypass housing, which is made of alum, I wonder if it was the engine or the housing generating the alum.

The results on the left are the same oil as above, only with the bypass filter added. NO OIL CHANGE. The lab suggested changing the oil at the prior sample due to the alum and high iron content. At this testing, they are content with the oil, and suggest sampling in another 3000 miles. Remember, it is the same oil without a change, just the addition of a bypass filter.

I'd like the iron to be lower, but if it's getting through the bypass filter, then it is under 2 microns, and is not going to cause much trouble.

I used an Amsoil one for a couple of years on a 350/300 in a boat and it worked real well. The oil never even looked dirty(still changed at 50 hours though). I did get a little rust on the filter case itself, but nothing too horrid.
