Motor oil is used for lubrication of internal combustion engines.
The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents).
Does engine oil make a difference?
Used motor oil shows a lot thicker and sludgy in conventional oil vs. synthetic oil, given the same amount of wear. Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits.
What does changing your oil do?
An oil change consists of removing the old oil from a vehicle’s engine and replacing it with new, fresh oil. The engine oil filter is usually also changed at the same time. Oil lubricates the engine and absorbs heat, allowing the internal parts to work together effectively without overheating.
Does oil make your car faster?
Old oil will reduce engine performance, lower its horsepower, reduce its mileage and eventually shorten its life. Be sure to get your oil change in accordance with the recommendations of your vehicle owner’s manual.
