Wear particles can scour away piston liners, cam lobes, piston rings and other engine parts, reducing combustion efficiency and causing the engine to burn more fuel to produce maximum horsepower. Wear in the valve train can disrupt timing and valve movement, while ring, piston and liner wear reduces volumetric compression and contributes to blow-by.

By-pass Filtration that removes particles smaller than 10 microns directly correlates to reduced engine wear and optimum efficiency. In the article “Clean Oil Reduces Engine Fuel Consumption” on Machinery Lubrication magazine’s website, the author surveys a number of studies that confirm this. Studied over 50,000 miles of service, buses fitted with Cummins six cylinder 8.3 liter turbocharged engines achieved 2 to3 percent gains in fuel efficiency while operating with six-micron by-pass filtration. A second study of a six-cylinder diesel engine saw dramatic improvements after installing a by-pass filter rated 75 percent efficient at six microns: oil contamination dropped 98 percent, friction decreased 2.9 percent and fuel economy increased 5 percent.
