Centrifuges

I bought a Spinner 2 about 70 days ago and have about 24,000 miles on it so far. My first oil sample came back with 0.0 for soot and all my metals were at least 10 points lower. I pulled the spinner apart after 10,000 miles just to see what I was catching and was I ever surprised. My motor has always had clean oil samples, but with only 10,000 miles (spinner and new oil) I had a little more than a 1/8" of sludge on the walls. Personally I don't think I would like the idea of more oil draining on top of the valvetrain. Yeah you would get a little more lube protection, but think of all the extra oil that would be flung around and sent out the breather tube. Also there would be a slight power loss from all the extra oil windage. This would be very small and not noticeable unless on a dyno.

 

I would go with the same spinner as pulling trucker and hook it up as per the instructions.
Pullingtrucker are these results after running Hi effiecincy oil filters??

 

I've ran CAT Hi-efficency filters since the motor was new. So at least my before and after results are based on very few variables which is what I was going for. I can't wait for another 6,000 miles and see what kind of results I have from a 30,000 mile service interval.

Besides the oil drain back issue that I would be worried about I would also be worried about the gasket failing or the valve cover cracking and letting debris into the engine. But I think these failures would be rare. I say if you feel comfortable about the idea...give it a shot and let us know how it does. To make sure its working properly I would do at least 4 oil samples before and 4 after install.

 

Acgo Sisu uses a spinner filter on their combine engines. and they do help. After running 100 hrs the oil used to be black as coal, and much thicker. Several dealers had engines that needed to be flushed to get all the contamination out of the oil pan.

Their system mounts of the side of head and is monted directly to head, not valve cover. So far the oil is still black, but the oil anaysis shows 65% less soot. in 100 hrs.

Its not the same application as a OTR truck but thats my experience with these filters. They do work and I think they are worth the money.

 

Here are a few pics of the debris I cleaned out of my Spinner 2 after about 27,500 on the oil, CAT Hi-efficency filter, and Spinner 2. The crude was about a 1/4" thick and the bowl was caked from top to bottom with it. Matter of fact even the "roof" of the canister was coated pretty good. After seeing this I will never run a truck motor with out a spinner. Heck I would thinnk twice about even running a canister type bypass system just for the fact if the element tears the debri can get back into the oil.

 

I've been running a Spinner for about a year, I do an oil analysis every 10,000 miles and my oil change interval is now 40,000 miles.
They tell me I can run it longer but I just can't bring myself to do it.

Like was said before, I will never run a truck without one again!

 

How does it handle getting water and anit-freeze out? Was there an improvement for those item on your oil analysis? Usually those are absorbed by the filter elements so I still have reservations considering the negative effects of even small amounts of anti-freeze on bearings.
