Synthetic oil was first produced in the middle of the last century for the extremely hot conditions of jet engines. Used for years in auto racing, synthetics were adopted into the mainstream automotive industry in the 70’s.
Almost every major auto oil company produces a synthetic line of oil. What most people know about synthetic oil is that it’s substantially more expensive than conventional oil. What many don’t realize is that it greener and a better long term option.
Synthetics last longer. Their standardized molecule chains hold up much longer than the mixed batch of molecules in conventional oil. That is why conventional oil changes are recommended typically at every 3,000 miles while synthetics can go to 7,500 miles and beyond. This offsets the price difference and reduces the amount of used oil that has to be disposed. It also decreases the amount of oil we need to produce and import.
Synthetics help engines run better. Synthetic oil outperforms conventional oil at both ends of the temperature spectrum. It flows better at extremely cold temperatures and holds up better under extreme heat produced in engine blocks from things like towing, running the AC on a hot day and racing. Even if a car is not driven in these extreme conditions, synthetic oil will provide more consistent lubrication, helping keep the engine running smoothly. A more efficient engine needs less repair and gets better gas mileage, which is another saver for the environment and the pocket book.
