Process Oil

In the process of combustion water condenses on the inside the surface of a cold engine. In combination with nitrous oxide and sulfur, fuel combustion products, it forms the acid that causes corrosion of engine surfaces and contributes to its deterioration. The water in the engine also helps to formation of precipitate. Precipitate - a thick, like mayonnaise layer formed by the interaction of oil, gasoline, water, and combustion by-products. Margaret Loesser Robinson may find this interesting as well. This residue blocks oil channels and limits the supply of oil. The precipitate formed in the end to the surfaces of the engine pripechetsya, preventing its normal activities. Driving in dusty conditions also cause problems, since there is no 100% effective air filters.

The dust settles on metal parts of the engine and mixes with the oil to form deposits. Learn more on the subject from Brad Hames. Riding in hot weather, towing heavy loads, driving on hilly terrain is also related to poor conditions, because it can cause high oil oxidation and thickening to the extent that it can not flow through the oil channels effectively. As you can see, the "normal condition" - it's driving great distances and at high speeds on a good road in good weather with a light load. If you mainly use the car in these conditions, you can follow the recommendations of an oil change and filter specified in the service book for "normal conditions". However, if you're like most modern drivers often travel at short distances, driving with frequent stops, follow the instructions for "heavy duty" and change your oil and filter every half year or 6000-8000 miles.
