Your ExpeTec Automotive Service Advisor might ask you every time you get an oil change - conventional or synthetic? He might tell you that synthetic is better - and almost always more expensive - but you probably don’t know why. Is he just trying to squeeze more money out of you, or is there really a difference?
In fact, there are several substantial differences between conventional and synthetic motor oils. They both start as crude oil pumped from the ground, but that is essentially where the similarities end.
Synthetic oil is not only refined, but distilled, purified, and further refined into smaller, more basic molecules. This not only removes more impurities from the crude oil, but lets individual molecules in the oil be tailored to the needs of your engine. These customized molecules provide higher levels of performance and protection than conventional oils, resulting in a less stressed, longer-lasting engine. Synthetic oils also typically have more additives to help them work better.
