Cleantechnics International Inc. has introduced a bypass filter system that is said to substantially extend oil drain and filter change intervals, as well as engine life. Due to exhaust gas recirculation devices tied to EPA emissions reduction mandates, a greater volume of smaller contaminants is flowing into new engines’ oil systems, the manufacturer observes, adding that bypass filter technology is becoming increasingly important to maintain oil performance levels.

Whereas normal spin-on or full flow filters are designed to capture 25-micron and higher particulate, Cleantechnic engineers note, the new bypass technology filters 99.5 percent effectively at the one micron level. That capability is critical to maintaining peak engine performance and fuel efficiency, they add, since the smallest contamination does maximum damage to the engine, acting like sandpaper between pistons and sleeves to cause surface scoring that, in turn, leads to reductions in engine pressure and fuel efficiency. Through the bypass filter’s virtual elimination of oil system contamination, friction in the engine reportedly is reduced by more than 2.9 percent, producing a 5 percent increase in fuel efficiency [SAE 881827]. Moreover, the resulting reduction in engine wear delivers engine life extension of up to three times the average [SAE 710813], system developers contend.

The bypass filter load reaches up to two gallons of water and 22 lb. of particulate contamination. Increased load ability allows filter change intervals of up to 90,000 miles and oil drain intervals of up to 360,000 miles. Thus, in view of oil maintenance, fuel efficiency, and life extension savings, cost reduction potentially amounts to as much as two cents per mile.


The PremierCare Connect program expands its service with a new express option offering small fleets an automated parts-ordering system. Connect Express is designed for fleets of 10 or more vehicles and small maintenance shops requiring a straightforward program to purchase parts without full fleet-management capability.
