As a part of the oil change series, I want to include synthetic oils. I am asked for my opinion, all the time. Do I recommend using synthetic over traditional oils? There is nothing wrong with traditional oils. In my last note, I explained how traditional oils work. When using synthetic oils, there are advantages and disadvantages. Before using any type of oil or chemcial in your vehicle, check your owner's manual for guidance.
Synthetic oil came into the picture during WWII. It was used in airplanes. In the mid 1960s, it was marketed and produced for automobiles. The oil was a substitute for the traditional oils that lacked the necessary ingredients found in traditional oils. Today, traditional oils have caught up to its counterpart. But, the war over traditional and synthetic oil continues.
The technical advantages of synthetic motor oils include:
Better low and high temperature viscosity performance
Better chemical and shear ability
Decreased evaporative loss
Resistance to oxidation, thermal breakdown, and oil sludge problems
Extended oil change intervals with the environment benefitting through oil waste
Improved fuel economy for certain vehicles
Better lubrication on cold starts
The disadvantages of synthetic motor oils include:
Today's cost of synthetic motor oil
Potential decomposition problems in certain chemical environments
Potentially not a benefit for older model vehicles
It's not recommended to switch back and forth between using synthetic and traditional motor oils. As stated in the advantages, your vehicle will become accustomed to operating at a slightly higher temperature. No matter what type of motor oil your vehicle uses, it still will need changing.
