Five Lethal Engine Oil Contaminants

Some contaminants are important to monitor and analyze because they are root causes of premature oil degradation and engine failure. Other contaminants are symptomatic of an active failure condition that requires a response other than just an oil change. For instance, seal damage leading to fuel dilution or glycol contamination cannot be remedied by performing an oil change or switching to a better quality lubricant.

Such symptom-based contaminants are also root causes that enable new failures to occur. The value of oil analysis in detecting problems early goes without saying.

Any one of the contaminants described below is capable of causing premature or even sudden engine failure. It is worth noting that problems are more pronounced when contamination combos exist, such as high soot load with glycol or high soot load with fuel dilution. There are numerous failure pathways and consequential sequence of events.

Thousands of engines fail prematurely each year aided by the presences of glycol, fuel, soot, water and dirt (silicon) in the engine oil.
