CORROSION - 2

It is critical to operate en engine at normal operating temperature to prevent, as well as burn off any water that is present by an evaporation process. The most severe type of driving an oil can be subjected to (as well as an engines internal components) is short drives and intermittent operation in which the engine and oil never has time to reach normal operating temperatures for an extended period of time. A quality motor oil will have a corrosion inhibitor added. Corrosion inhibitors also vary in terms of effectiveness, quality and quantity. Again, less costly oils may not protect against corrosion as well as more expensive motor oils that have a better corrosion additive package. Some common corrosion inhibitors include ZDDP (Zinc Diethyl Dithiophosphate), Calcium and Barium Sulphonates.
