Consequences of Failure to Maintain Motor Oil
What happens when the motor oil is not maintained?
-- Bob Kayla, Dickinson, TX
Over time, oil and the additives used in the oil break down and thermally degrade. And because the circulating oil picks up debris and other contaminants of combustion, it must be eventually changed to get rid of these contaminants. Higher quality oils like Mobil 1 that contain higher quality base oils and additional additives last longer and are able to hold more contaminants than lower quality oils. This is why synthetic oils can allow longer times between oil changes as compared to conventional motor oil.
