Bypass Oil Cleaning Centrifuge - 10x more cleaning power than a filter 
The pressure from your engine spins the centrifuge removing particles as small as 1 micron or less. 

Did you know that soot will enters an engines lubrication oil at the rate of .0048 oz for every gallon of diesel fuel burned? Burn 210 gallons you get 1 oz of soot in the oil. Burn 3360 gallons and get 1 pound of soot in the oil. A large truck will burn 1,786 gallons of fuel every 12,500 miles, at 7 mpg. 

During this 12,500-mile interval, more than half a pound (8.5oz) of soot will enter the oil. 

Your standard oil filter doe not catch most of this soot! Today's engines have what is called a full-flow oil filter. These filters generally filter to 25 microns. Two things that you may not know are: (1) A 25 micron filter is only 80% effective, meaning 20% of particles larger than 25 microns are NOT held in the filter and go out to wear out your engine. (2)The other point is that the average oil film thickness between components in your engine is 5 to 20 microns. According to the SAE, particles as small as 4 microns can cause up to 77% of engine wear. 

The Dieselcraft Centrifuge cleans engine oil by generating a centrifugal force which is 2,000 times greater than gravity.

Engine oil pressure spins the rotor at 6,000 rpm's. That force separates the solid contaminates from the main oil supply while slinging the solids to the inside walls of the rotor, which is easily cleaned. Contaminant particles less than 1 micron are removed, eliminating the wear and tear on close tolerance metal parts by at least 50%. 

The Dieselcraft Centrifuge remove dirt and wear particles from the oil flow altogether and remains constant, whereas filters take out solids and hold them from circulating further, but plug, reduce oil flow, and eventually reach the point of not working. In engine applications, oil change intervals using conventional oil can be extended to two if not three times. 

With synthetic oils, oil changes can be extended over 40,000 miles or 750 hours. Replacement filters and disposal costs are also greatly reduced. Lab testing of oil is needed to determine the correct change interval for each application.

At long last, I'm happy to report that we have been having strong success with your oil recycling unit. Our Mitsubishi truck runs well on the mixture we are using. We also just started service of about 10 barrels per month of waste oil from one of the Embassies here in Port-au-Prince. We are considering a project expansion into more regions of Haiti, which could lead for our work to require several more units. I will let you know as the current proposal works its way forward. Thanks again for developing a quality product, and I look forward to contacting you again soon. Best Regards,

I replaced my oil and oil filter at the time of the oil centrifuge installation.I was starting with clean oil and new oil filter. After about 6000 miles, I cleaned this unit and was AMAZED at what I took out. I scraped and peeled out a 1/8" rubbery black goop from the oil centrifuge.
What I have found just by my seat of the pants assessments are as follows; On this last 6000 mile trip out west I averaged about 1 mpg better [at just over 9 mpg] than I ever have before. Usually on long trips I am around 8 mpg on average. This trip, on several tanks I got over 10 mpg when I had a good tail wind. I have never got this before.
My cruising speed stays constant at about 63 mph and about 1750 rpm with the 16R20's I am running. I have also not used any oil in the last 6000 miles - checked it a few days ago. 
The oil is actually cleaner too - ordinarily I would have to wash the oil of my hands in order to clean the black soot off. Now I can just wipe my hands with a paper shop rag and that takes the oil and soot off my hand, so my impression is there is far lower soot concentration in the oil - which is good for the engine.

Hello, I purchased this centrifuge and installed it on my Dodge Cummins. 

Works great! Just drove 5000 miles and had a layer of tar type substance in the filter. 

Glad to know I am keeping this out of my engine.
