COMBUSTION BY-PRODUCTS CAUSE ENGINE COMPONENT DAMAGE
Only one type of contaminant left to discuss: combustion by- products. These little buggers can wreak havoc in an engine. Not only can they form deposits on the inside of an engine which will rob it of performance and, ultimately, life expectancy, they will also tend to raise the acidity of the lubricant. Higher acidity levels in your oil can lead to severe corrosion and break-down of engine components. In turn, this break-down leads to more oil contaminants and the necessity for an oil change.
Three things keep these contaminants in check: the TBN of the oil, high efficiency oil filtration and tight ring seal. The most important of these three is ring seal. If the number of combustion by-products entering your oil can be reduced, there will be less necessity to remove or neutralize them.
Poor ring seal allows combustion by-products to pass from the combustion chamber into the crankcase where they contaminate the oil. Tight ring seal keeps them out. Synthetic motor oils encourage a tighter ring seal than petroleum motor oils do.
TBN (total base number) is a measure of how well a lubricant can neutralize acidic combustion by-products. The higher the TBN, the better the protection against these acidic by-products and the longer it will last. This is an area in which numbers can vary greatly even among synthetics, but most high quality synthetics will have TBN numbers that are significantly higher than many petroleum oils.
Amsoil Solutions
For nearly three decades, AMSOIL INC. has been recognized as the leader in synthetic lubrication technology. AMSOIL was the first to introduce a synthetic motor oil qualified by the American Petroleum Institute, the first to recommend 25,000 - mile / 1 year drain intervals, the first to recommend 35,000 - mile / 1 year drain intervals, and the first to implement a system for dramatically increasing drain intervals with oil analysis. Decades of research, laboratory analysis and millions of engine miles have kept AMSOIL the leader in automotive applications for synthetic lubrication. Although the results have paid off in maximizing efficiency and minimizing waste, they are not conclusive. AMSOIL is the leader in synthetics and with continued research, analysis and product development will remain the industry's leader.
