Synthetic Oil Characteristics
Unlike conventional oils, synthetic oils are not distilled from petroleum sources. Because they are artificially produced, they do not have the natural limitations inherent in conventional (petroleum-based) oils even after such conventional oils have been treated with additives by their manufacturers.
Synthetic oil generally flows better at extremely cold or hot temperatures, lasts longer, lubricates better, cools and cleans parts more efficiently, and leaves fewer engine deposits (when oil touches extremely hot parts). Engines start easier and parts are lubricated faster with synthetic oils. If an engine normally consumes a little oil, use of synthetic oil should reduce such consumption. In essence, frictional cold start wear is reduced.
