Bypass oil filtration technology was originally introduced to the trucking industry in the 1930's. It was the exclusive means 
for filtering engine oil from the early 1930's until the early 1960's. At that time, engine manufactures moved away from bypass 
filtration when full flow filtration became vogue. People saw full flow as having the ability to filter all the oil at once as opposed 
to the 10% at a time that bypass filtration does even though full flow filters don't have the ability to filter out anything but the 
largest particles out of the oil. Factory full flow oil filters are not even designed to purify the oil down to a single digit micron 
level but mainly to filter all the oil at a high rate before it gets to the engine. Since full flow filters filter the oil at such a high flow 
rate, it is unable to trap the microscopic particles that enter the oil and which can damage your motor. During the last 10 years 
bypass filtration interest has been re-sparked and has been positioned mainly as a way for fleets to extend engine oil life and 
oil drain intervals. People now realize you can have the best of both worlds by running bypass filtration along side your full flow 
filter. This allows the full flow filter to catch the large particles and the Kleenoil Bypass Filtration System to to catch particles 
down to 1-micron in size, all the water and acid, as well as the soot that will inevitably end up in diesel engine oil.

Kleenoil Bypass Filtration Systems can help prevent a buildup of contaminants that can score bearings, rings and cylinder 
walls of the expensive engines in your truck fleet. Contamination also can contribute to an increase in viscosity and gum
deposits on rings and valves. Because filtration is necessary for effective engine protection, it is important to make sure you 
have the best available system in good working order. According to Fleet Equipment Magazine, 60 percent of the potential 
causes of wear and failure can be eliminated by well-designed and properly applied filtration systems.

Kleenoil Bypass Filtration Systems are especially beneficial on the newer EGR (exhaust gas recirculation) diesel engines as 
they will run hotter and produce more soot and acids than previous models of diesel engines. The very nature of how these newer 
EGR engines function makes Kleenoil Bypass filtration a must have on these newer trucks! Most engine builders have decided 
that cooled EGR is the most effective way to reduce combustion temperatures. Small amounts of exhaust gas will be piped to the 
chambers to displace oxygen; less oxygen means cooler combustion. Before going to the cylinders, some of the exhaust gas heat 
will be absorbed by the engine's coolant, thus the term “cooled EGR." Federal rules now require diesel engines to produce about 50% 
less nitrous oxide, or NOx, than current diesels thus the reason for the newer EGR diesel motors. More heat, soot and acid will form 
during combustion in most of these new EGR diesels, say engineers. With greater amounts of soot and acid making it's way into the 
engine oil, the Kleenoil Bypass Filter is no longer considered an optional item. It is a must have if you want to reduce operational costs 
and maximize the life of these expensive engines!
