In other words, they allow much more efficient operation of equipment. Synthetic Oils Like petroleum oils, there are poorly made synthetics as well as properly made synthetics. Synthetics are put together from individual components in a controlled environment. The highest quality components and particularly close attention to detail is the only way to produce a superior synthetic lubricant. While there is much debate over which is better, simple facts determine their use.
Synthetics withstand more heat and degrade slower than petroleum oils.
However, a properly refined petroleum oil can perform almost as well as a synthetic can. On an efficiency down side, synthetics cannot hold as much additives as a petroleum oil. Because of the down side to synthetics, they have not replaced petroleum oils in the industrial market place. There is a definite need for both petroleum and synthetic oils and that is likely to remain the rule for years to come. There is good news concerning this battle, however.
