What are some of the common misconceptions about synthetic motor oil?
It is interesting how some of these myths hang around for so many years. Some of the most common were that synthetics are not compatible with seals (properly formulated synthetics actually extend seal life), that synthetics are too thin to stay in the engine, and that synthetics cause cars to use more oil. Of course there are misconceptions going the other direction, too. Some people think synthetic oil is a super oil that will last forever. It is true that synthetic oils are more impervious to oxidation, but the additives in synthetic formulations do get used up over time. A motor oil’s formulation includes the performance of both the base stock and additive package.
