CONTAMINATED OIL

In our present day and age consumers are paying greater attention to the maintenance on their vehicles as budgets dictate they will be extending the time line of ownership to 10 years. Clean engine & transmission oil is number one on the preventative maintenance list and this is achieved by following regular (manufacturer suggested) oil changes.

There are other methods also, but lets first look at what is achieved by changing the oil at regular intervals. The dust, carbon and broken down oil additives are removed along with some of the metal contaminants. Research indicates that consumers believe if the vehicle's oil and filter is changed, they will remove impurities from the engine system. Although a large number of contaminants are removed during the oil change, a significant number remain on the inner surfaces of the engine. These inner surfaces include rocker arms, push rod ends, the tops of hydraulic lifters, as well as the inside of lifters, oil galleys, cam and crankshaft bearing surfaces, front and rear engine seals and many other surfaces and areas that allow viscous engine oil to cling or gather. When new oil enters the system, contaminants are picked up and begin the wear cycle again.

DAMAGE DONE BY 10 MICRON SIZE IRON/STEEL PARTICLES

The most damaging contaminant size is ten microns and smaller enabling the contaminant to flow within the film of oil and enter high-pressure areas of the engine ploughing and tearing the surfaces. The most damaging of the metal contaminants are the hard metals; iron and steel which are ferrous metals.

NEW ENGINE OIL CONTAMINATED THROUGHOUT MANUFACTURING PROCESS

Metal contaminants are introduced into the engine at the time of manufacture, as the fine grindings are impossible to flush out. New oil is contaminated with ferrous metal contaminants under the ten-micron range when it is pumped from the ground to the refining process. The oil is pumped by metal pumps through metal pipelines and stored in metal reservoirs then transferred into containers for sale from quart size containers to forty five-gallon drums.

HOW STOCK CAR FILTERS FUNCTION

Although oil filters are not usually advertised with a filtration rating our research has identified they are generally rated at a 25-micron capability. That is, they will remove contaminants 25 microns in size and higher. It is important to note this is an average rating not an absolute. If the filter micron rating is lowered, the flow of lubricant is reduced and the system will starve or bypass.

ENGINE FAILURE CAUSED BY OIL CONTIMINATED BY 10-MICRON SIZE PARTICLES

From a number of important new field and lab studies we can now conclude that lube oil contamination is the primary cause of engine-wear, and begins what is referred to as the chain-reaction to failure. In diesel engines, high local stresses associated with sliding contact wear result in abrasive removal of material surfaces. When loads are concentrated on the effective area of a small particle, the resulting surface stresses can be greater than 500,000 pi. Oil film thickness between which particles can reach and attack surfaces, are typically in the 10-micron range. This explains why, according to a wear study by Cummins Engine Corp., particles smaller than 10 microns generated about 3.5 times more wear (rods, rings, and main bearings) than particles greater than 10 microns.

An independent European University study, as published in Lubrication Engineering Magazine, reports a reduction in diesel engine wear by a factor of 14 when better lube oil cleanliness is maintained. In reference to gas turbine engines, the U.S. Department of Defence states that "approximately 30 percent of all engine failures are caused by metal particulate contamination in lubricating oil systems."

REMOVE ENGINE OIL CONTIMINATION WITH BEARTRAP

The most effective method to remove the Iron and Steel contaminants is when the engine is running. The oil while under pressure picks up all the contaminants and funnels them through the filter. Alone the filter will remove the contaminants over 25 microns, but with the assistance of The Bear Trap a Magnetic device attached to the filter, the most damaging contaminants under 25 microns, the Iron and Steel will be removed. When these hard contaminants are removed the wear cycle is slowed down. Oil analysis has identified when the hard metal count is reduced; the soft metal count is lower.

The Bear Trap is especially effective when used new or rebuilt engines, as the break-in stage will produce a large amount of tiny ferrous metal contaminants. Application of a Bear Trap will remove the ferrous contaminant during the break-in stage thereby extending the engines life and reducing future maintenance costs.

CONCLUSIONS

The hard metals; iron and steel are the most damaging of all contaminants and deserve closer attention in relation to the filtration of oil. There is a lot of "grey area information" regarding the filtration of oil that needs filtering. Engine technology has improved dramatically over the past thirty years with higher manufacturing tolerances and harder working engines. The oil has improved also but the common oil filter has not improved much. The Bear Trap will greatly improve your filtration capability and extend the life of your equipment. This will protect your investment, reduce maintenance costs and increase the operational time over the length of ownership.
