Trucking Fleet Applications

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 which can damage your motor. During the last 10 years bypass filtration interest has been sparked and 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 alongside your full flow filter. This allows the full flow filter to catch the large particles and the Kleenoil Bypass Filtration System 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 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 its 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!

Installation and Maintenance Schedule for Trucking Fleets with Kleenoil Systems

Take an initial oil analysis on your existing oil in your truck when your normal oil change interval is up PRIOR to installing the Kleenoil System. This will give you a baseline reading so you have something to compare against once you have your Kleenoil Bypass Filtration System installed. Installation of the Kleenoil Bypass Filtration System on big rig trucks is typically on the frame of the engine compartment OR on the frame behind or slightly in front of the gas tank on the frame on the passenger side of the truck (see image above for example). Install the Kleenoil unit on the truck along with a fresh oil change and full flow filter change, change the Kleenoil bypass filter every 24,000 km and top off with oil. Take periodic oil analysis readings to get an accurate gauge on the oils current conditions and let it be the barometer on when to finally change the oil and full flow filter. The oil will likely come back good for at least 120,000 to 160,000 km. Most people see 160,000 km or more on the same oil. Let the oil analysis be your gauge on when to change the oil. If your TAN/TBN numbers still look good and the viscosity and particle levels are staying within spec, you can indefinitely keep the same oil in your truck.

Seeing is believing! Listed below are some oil analysis reports from trucking fleets!
