Engine Oil Cleaning
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 OC-25 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 OC-25 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.
The Dieselcraft OC-25 centrifuge is a compact bypass type systems. These systems measure less than 5 inches in diameter and is less than 10 inches tall; unlike other centrifuges it requires only a 1/4 NPT tapped hole to return the oil to the engine through a 3/8 ID hose.
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.
Because of its lower flow rate of .93 GPM, its physical size, and the unique oil return system, the OC-25 can be used on a wide variety of gasoline or diesel engines in any application: pick up trucks, gen sets, dozers, boats - it does not matter. If it has oil pressure and 12-24 volt power, we will clean the oil.The Model 180 AP is suited for large 30 gallon plus sump equipment.Lab testing of oil is needed to determine the correct change interval for each application.

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.

I got a 2010 Dodge Ram 3500 turbo diesel.
The engine oil light will come on before 3K miles. After installing the Dieselcraft OC-25 the oil change light have not come on. It is a solution for a problem that these trucks got. It is a good investment.
