Glycol contamination is common in engine oils and can greatly alter the properties of the lubricant. Antifreeze causes a thickening of the oil, increasing the viscosity and not allowing it to flow as readily as before. This can lead to boundary conditions in parts of the engine that require a less viscous fluid to properly lubricate and protect them. It also creates an acidic environment within the oil, resulting in corrosion within the system, especially on copper surfaces. The additives within the oil can be compromised as well.

Once contaminated, the oil continues the same route of flow, from the sump, into the crankcase, through various parts of the engine and through the filter. With the added glycol, these filters become plugged sooner, which can cause reduced flow and eventually, once the bypass pressure is reached, a condition in which you are no longer filtering your oil. This allows particles that normally would have been filtered out to remain in the system, disrupting the lubricating film and resulting in surface damage to components.

Antifreeze also mixes with oil to form small globules called oil balls. Although very small, typically 5 to 40 microns in size, they can cause big problems. These balls are abrasive and create surface erosion. A common place to see this would be on the inside walls of the cylinder, where the oil balls could cut and gouge into the wall. They can produce all types of surface fatigue and lead to lubrication failures in areas of very tight tolerances.

In my case, the culprit for this contamination was a cracked manifold, but there are several ways glycol can find its way into oil. If the piston heads are warped or cracked, contamination would be allowed into the system. In more severe cases, cavitation wear provides a straight path for ingression. Cavitation occurs when an air bubble implodes against a hard surface, resulting in a pitting action. As it becomes more aggressive, this can cause a hole or crack in the cylinder wall.

The first step to combating this problem is to discern that you have a coolant leak. Periodic checks of fluid levels are the easiest way to do this. If you notice levels beginning to change, try to find the coolant leak. Fixing the leak should be your first priority. Otherwise, any actions you take to clean the oil will be in vain. For most engines with small sump volumes, an oil change after the leak has been fixed will ensure that any contamination has been mitigated by new oil.

In systems with large volumes of oil, small leaks can be hard to detect. Oil analysis can reveal glycol in several ways. A patch test can show sludge or precipitates associated with this type of contamination. A blotter test is another simple test that can expose the presence of glycol. If the oil appears thick and doesn’t wick into the blotter paper very well, glycol contamination could be a possible culprit.

Although many years have passed since my breakdown on the road home, the lessons it taught me are still useful today. Simple inspections on all types of machines provide invaluable information as to their condition as well as reassurance that they are operating in a reliable manner.

 

MANUFACTURING PROCESS OF ENGINE OIL is not very complicated. For the production, there is need usable and tried a formulation, ingredients ( performance and another additives, base oils,foam agent, pour point depressant, etc. ) and process tank. For ingredients to be used, quantities to be used and ingredients usage rankings, you should look into this formulation and manufacturing process. Therefore, formulation and productıon process of MULTIGRADE, MONOGRADE,SYNTHETIC,SEMI SYNTHETIC MOTOR OIL are important. If you have not a good formulation, you cannot make healthy and  efficient production of any lubricating oils.
