1. How does the COT Oil Processor work?
The COT Oil Processor is a by-pass oil cleaning system that removes both solid and liquid contaminants.
Contaminated oil enters the COT Oil Processor at a slow flow rate. First, the oil enters the Filter Unit under pressure supplied by the engine’s oil pump. Solid contaminants such as wear metal particles, carbon, sludge, soot, dirt, silica and other foreign material down to the size of one micron are removed in the progressive cotton filter element.
After being filtrated in the Filter Unit, the oil, now free of solid contaminants, enters the heated Evaporation Unit through a metering jet that reduces the oil pressure to atmospheric pressure. The oil flows over a heated diffuser plate where liquid contaminants such as fuel, anti-freeze or water are evaporated and ventilated. The oil that is now free from both solid and liquid contaminants is finally gravity-fed back to the engine.

2. How can the COT Oil Processor save me money?
The COT Oil Processor will quickly pay for itself:
•••- Greatly reduced consumption and spill of oil.
•••- Greatly reduced oil change costs.
•••- Greatly reduced costs for handling and storage of oil.
•••- No cost for used oil disposal.
•••- Lower fuel consumption thanks to increased engine efficiency.
•••- Less major overhaul expenses.
•••- Higher re-sale value of your equipment.

3. 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-freeze that a standard filter doesn’t. The COT Oil Processor does not replace the conventional oil filtration system – it enhances and works in conjunction with it.

4. Why does the COT Oil Processor remove solids more effectively than other filters?
Most full flow and by-pass filters use paper filter cartridges that filter out particles down to the size of 25-40 microns. Only the best ones can capture particles down to 15 microns. Commonly, paper is used as a full flow filter medium but it can quickly get clogged with particles, dirt, soot, sludge or other contaminants. These filters work with the same principle as your coffee filter at home. If a full-flow filter gets clogged, a by-pass valve should open and let the unfiltered oil flow through the engine. Thus, the full-flow oil filter can become ineffective relatively quickly.
The COT Oil Processor has a cotton filter element that effectively removes particles down to 1 micron. The winding pattern of the element creates many identical spiral passages tapered in cross section so as to trap the larger particles near the outer portion of the element and the smaller particles as the oil flows inward through the element. Solids are filtered by entrapment in the filter media throughout the entire depth of the element, not only on the surface as with a paper filter.

5. Doesn’t oil wear out?
No! Oil never wears out – it just gets dirty! The bulletin #86 of the United States Bureau of Standard states: “It is a known fact that oil never wears out mechanically. Oil can be used over and over again, and still perform as new, as long as it is kept free of contaminants.”
Oil is permanently exposed to high temperatures, intrusion of metal particles and chemical contaminants. As oil becomes more and more contaminated, it looses lubricating and cooling capacity. The oil life decreases, and the engine is not efficiently protected.
Contamination is the primary cause of wear and engine failure and the main reason why oil has to be changed. The COT Oil Processor removes both solid and liquid contaminants from the oil and reduces or eliminates the need for oil changes.

6. Why is dirty oil so bad?
During operation, the engine lubrication oil gets contaminated by particles and liquids from the combustion process, from the outside or from wear on metals inside the engine or from general oxidation.
All petroleum products contain some amount of sulphur. The combustion process will create water, carbon particles and sulphur dioxide. These contaminants enter the oil through piston blow-by. When sulphur dioxide is mixed with water, sulphuric acid is formed which is highly corrosive. The sulphuric acid causes corrosion and pitting of metal surfaces in the engine and premature wear. Therefore it’s so important to keep water out of the oil. Even very small amounts of water are unacceptable.
Dirt, dust, acid and foreign matter also enter the lubrication system through piston blow-by, forming sludge, varnish and acids thereby adversely affecting the lubricating properties of the oil.
Apart from being a natural by-product of the combustion process water is also caused by condensation or introduced from the engine cooling system through leaking head gaskets. Leaky injectors or fuel not consumed by the combustion process are the primary reasons for fuel in oil.
The COT Oil Processor removes both particles down to 1 micron in size and liquid contaminants such as water, fuel or anti-freeze.

7. What happens to the additives when you use the COT Oil Processor?
The oil producers mix additives in their oils to fight contaminants generated by the combustion process and to prevent excess wear. The COT Oil Processor does not filter out, use up or influence these additives in any way. Instead, the COT Oil Processor make the additives last longer. Additives (e.g. viscosity helpers, encapsulating agents, rust inhibitors or neutralising agents for acids) are consumed in doing their job. Since the Oil Processor does most of the work for the additives, they are not consumed and last much longer. We have seen, through long-term testing, that an acceptable level of additives is maintained by the addition of oil at each filter change. The need for any other additives is not necessary, nor is it recommended, and in some cases may cause problems from excessive levels of chemically active additives.

8. Can the COT Oil Processor harm my engine?
No! The COT Processor does not replace the conventional oil filtration system – it enhances and works in conjunction with it. It’s an added benefit and not a substitution for any basic function of your equipment. The COT Oil Processor has no moving parts to wear out, but should any problem develop, your engine would simply continue to work as it did prior to installing the COT Oil Processor. If the heating element would fail or the filter would be blocked for any reason, it would only result in the oil becoming gradually contaminated, as it would under normal engine operation without a COT Oil Processor. A properly installed COT Oil Processor cannot obstruct the flow of oil to the engine’s moving parts, lower the oil pressure or harm the engine in any way.

9. Can the COT Oil Processor be used on any engine?
The COT Oil Processor can be installed on almost any engine such as automobile, truck, bus, boat, generator or any other type of industrial equipment with an engine or pressurised lubrication system. The COT Oil Processor will work well with engines using any type of fuel such as diesel, gasoline, ethanol or natural gas. It cannot be installed on engines without a pressurised lubrication system, such as 2-stroke outboard engines, where lubricating oil is mixed with the fuel.
The COT Oil Processor is also well suited for other systems where oil circulates and needs to be kept free of impurities e.g. in hydraulic systems.

10. Will the COT Oil Processor affect the engine manufacturer’s warranty?
No! The installation of a COT Oil Processor in itself does not void the engine manufacturer’s warranty. The engine manufacturers are responsible for what they build and we are responsible for what we build. In the unlikely event that a fault in the COT Oil Processor would cause damage to an engine we have a Product Liability insurance that will cover consequential damages, if any.

11. Can engine manufacturers require oil changes in order to honour their warranty?
No! Engine oil change intervals are recommended by most manufacturers for warranty purposes. As long as the condition of the oil meets the manufacturer specifications, the oil does not have to be changed to honour the warranty. The COT Oil Processor insures that the oil continuously meets these requirements. Manufacturers should honour engine warranty claims as long as accurate and periodic oil analysis reports are taken at the manufacturer’s recommended oil change intervals, stating that the oil is suitable for continued use.

12. Will the Oil Processor cause a noticeable drop in engine oil pressure?
No! The metering jet in the evaporation chamber controls the flow through the system so that the oil pressure is maintained upstream of the evaporation chamber. Downstream the oil flows down to the oil sump where there is no oil pressure. In this way the engine oil pressure is not influenced.
