SYNTHETIC MOTORS OILS VERSUS CONVENTIONAL MOTOR OILS
Synthetic motor oil can cost up to three times more than regular conventional motor oil. Is the added expense of using synthetic oil an added value or a waste of money?
Dealerships, auto repair shops and fast lube facilities will often recommend using synthetic oil when a vehicle is brought in for an oil change or routine vehicle maintenance. Naturally synthetic motor oil is much more expensive than conventional oil, so before making a decision, find out the differences between synthetic and conventional motor oil and what it means to a car’s engine.
What is Conventional Motor Oil?
Conventional or regular motor oil is processed from crude oil out of the ground. The crude oil is separated at the oil refinery. The thicker oil is used for applications like roofing tar and asphalt. The thinner oil is used for applications like gasoline and engine oil, among other applications. This oil becomes the base stock for the oil. Engine oil base stock refined from crude oil contains small amounts of natural contaminants that can’t be removed from the base stock used in processing engine oil.
What is Synthetic Motor Oil?
There are two components to synthetic motor oil like a Conventional Motor Oil:
1. Base Stock - Unlike conventional motor oil, synthetic motor oil’s base stock is artificially created or synthesized. Because of the higher purity of synthetic oil, the properties of synthetic motor oil can stand up to heat much better before breaking down
than conventional motor oil. Synthetic motor oil can also withstand colder temperatures better than conventional motor oils. This is a huge benefit when an engine is first started in cold weather.
2. Performance Additives - Beside the base stock, performance additives are added to both conventional and synthetic motor oils. According to ‘Oil Experts’ the performance additives used in synthetic motor oils are engineered with special additives that help to fight off sludge and mineral deposits that are naturally caused by combustion. Performance additives in synthetic motor oil provide superior protection in extreme driving conditions like extremely cold or hot temperatures.
So is Synthetic Oil Better than Conventional Motor Oil?
There’s no doubt that synthetic oil is better than conventional motor oil. Since synthetic oil is made with smaller molecules and has fewer impurities it’s just a plain better lubricant. It’s especially better for today’s modern engines that have tighter tolerances and smaller oil passages that need a super lubricant. Car manufacturers are requiring that synthetic oil be used more and more. Most new vehicles are at least required to use a synthetic blend. General Motors is now requiring full synthetic motor oils.
