A 10% REDUCTION IN MAINTENANCE COST IS EQUAL TO A 40% INCREASE IN COMPANY REVENUE
Studies conducted by a large manufacturer of heavy trucks using sub micron filtration concluded that a filter that can filter under 1 micron results in an 80% reduction on compression rings and a 50% reduction on oil rings.

When filtering the used oil through a 5 micron filter the wear remained almost unchanged, but the 1 micron filtration significantly reduced the wear rate by 1⁄2 on the oil rings and 1/5 on the compression rings.

“Oil is like any mineral and can not wear out. Oil can become dirty and contaminated but, like copper, iron or silver, when they are reprocessed, they are as good as new. Studies have shown that oil significantly improves lubricating qualities as it is exposed to heat during use in the engine”
