If you could filter oil in the engine down to 1 micron or below, your oil would stay clean all the time. This is exactly what the Kleenoil bypass filter does. This process cannot be accomplished in the main oil flow. Kleenoil filters do it in a bypass loop (thus the name Bypass Filtration). It uses a cellulose filter medium that not only filters particles down to the size of 1 micron or less, but it also filters 100% of any water that may accumulate through condensation, or through the combustion process itself. This eliminates the possibility of corrosion and hydro-cracking. Water contamination in lubricants can cut bearing life by as much as 80%.
For trucks with pan capacities of up to 11 gallons, the cost of the Kleenoil bypass filter is $649. With immediate savings of around $1,000 per year, the cost of the unit is written off in about six or seven months. Bypass filter cartridge replacements, changed at the old oil change frequency, will cost around $29 each. Other units are available for heavy equipment and also for smaller vehicles and engines.
