Conventional Or Synthetic Oil: A Guide
When it comes to engine oil, you have two main choices – synthetic or conventional. What you may not understand is the differences between the two, which can make it difficult to choose the right one. The following guide will help you become better versed in these two oils so that you always use the right one in your engine.
What's the difference?
Synthetic oil is created in a lab. It consists of man-made oils and lubricants, combined with a variety of additives. The additives depend on the specific uses of the oil, such as whether it is for a car engine or a piece of equipment. Conventional oil is a true petroleum product, mined from the ground. It does undergo a purification process and it may also have additives in it to improve performance. There are also synthetic blend oils, which contain a mixture of man-made lubricants and conventional oil.
Can they handle the heat?
As a general rule, synthetic oils out perform in high heat situations, which means you often find them in vehicles that are tuned for higher performance or in equipment that is bound to produce more friction as the motor runs. Conventional oils are generally used in newer cars that aren't used at high speeds or for heavy hauling, or in industrial motors that aren't under a heavy load.
Are contaminants an issue?
Contaminants are the main concern with synthetic oil. Contaminants can come from multiple sources, such as metal shavings that form through the natural running of the engine. These contaminants can ruin the viscosity of a synthetic oil, so synthetics are typically reserved for closed systems that are less prone to contamination, or when frequent oil changes are required. Conventional oil can withstand some contamination without losing too much viscosity, which is why it is used in many consumer vehicles.
When is synthetic oil absolutely necessary?
Engines and motors that must run in cold conditions almost always require synthetic oil. This is because it can be formulated so that it doesn't thicken up as the temperature drops. Cold, sluggish conventional oil doesn't lubricate as well in cold weather and it can become gummy – making it difficult to even start an engine. Synthetic oils are also sometimes necessary in high-friction engines, since they can be formulated to better deal with the extreme conditions in these engines.
