What is the difference between the COT Oil Processor and the original oil filter?
The original oil filter mounted on your engine is a full-flow filter where 100% of the engine oil passes through at high speed (200-4000 litres/hour). Since the speed of the oil is so high, only larger particles (20-40 microns or larger) can be filtered out. About 90% of the particles in the oil, however are smaller than 5 microns and can still pass through and cause wear on moving parts in the engine. SAE (Society of Automotive Engineers) Technical Paper #902238 concludes “Contaminants between 2 and 20 microns in size can be particularly damaging since they can disrupt hydrodynamic lubrication by entering between wear surfaces”. The COT Oil Processor is a by-pass system where only a small amount of oil is taken from the engine at a slow flow rate (27 litres/hour). Therefore the filter can be much finer and the COT Oil Processor can take care of particles down to 1 micron in size. Apart from that, the COT Oil Processor also evaporates liquid contaminants such as water, fuel or anti-fre
