Finally, there are three overall types of oil: natural, synthetic and synthetic blend. Natural oil contains the greatest amount of impurities that will contaminate an engine over time, but tends to be the cheapest of the three types. Synthetic oil generally costs up to three times as much as natural oil, but contains significantly fewer impurities and lasts longer. Blend is a mixture of natural and synthetic oils, and it is usually cheaper than pure synthetic.
