any way to test what viscosity of oil is in a car

An insufficiently lubricated engine risks overheating. Viscosity breaks down, and it loses its lubricating qualities.

Like all automotive fluids, engine oil gradually deteriorates. All of them are completely avoidable if you change your oil. Many of these problems are potentially costly. Not changing your engine oil can have a wide range of consequences, from a voided warranty to severe engine damage. What happens if you don’t change your engine oil? – increase in the content of impurities such as combustion soot, wearing metals, and external pollutants (like dust and water).Ĭhanging your oil at regular intervals not only ensures that your engine runs properly, it saves you money on fuel and helps to reduce emissions. – loss of efficiency from increased viscosity and acidity (oxidation) – degradation by mechanical and thermal actions (like shearing and oxidation) There are several consequences for oil quality: In many countries, the time interval between oil changes in road vehicles has increased considerably over the past 20 years. Old, dirty oil also causes hydrocarbons to build up in the engine’s crankcase, forming “sludge.” This sludge at the bottom of the engine decreases the flow of oil, which can lead to poorer protection or even overheating of the engine. As this happens, friction inevitably takes its toll on your engine’s performance, and thus its fuel economy. These additives degrade, while contaminants will gradually saturate the oil and reduce its lubricating qualities. Engine oil also contains additives that help prevent corrosion and oxidation. As it flows through the engine, engine oil picks up natural byproducts of friction and combustion, like metal particles and soot, as well as other contaminants like dust and fuel impurities. Oil’s primary purpose is to lubricate your engine’s internal parts, thereby reducing the damaging effects of friction. But, like all engine fluids, oil deteriorates over time, so regularly changing engine oil is essential to proper car maintenance. Engine oil lubricates, cleans, and protects internal parts from corrosion. Your car cannot function without engine oil. Why should you regularly change your engine oil? Regularly checking and changing your engine oil is vital to keeping your car in running order. As oil deteriorates it loses its ability to lubricate, clean, and regulate the temperature of your engine’s components. Your car’s engine cannot run without oil, but like any other fluid, it deteriorates with use.
