Many car owners and drivers pay little or no attention to the oil demand of their vehicles. This nonchalance has often resulted to fatal consequences. The role of engine oil in the overall health of a car’s engine cannot be overemphasized, it is indeed one of the necessary auto maintenance procedure. Changing a vehicle’s engine oil is as important as having it in the vehicle’s engine. Constant check on a vehicle’s engine oil level is generally recommended to ascertain when to top it. Still, changing the entire engine oil and knowing when to do so is as well crucial.
Knowing the functions of engine oil and how it works is key to understanding the need to constantly change it. Lubrication is the major function of engine oil. Engine oil lubricates engine’s moving parts. Lubrication reduces wear and tear resulting from friction between moving engine parts. Friction also could cause a vehicle’s engine to work harder than normal and heat the engine up to abnormally high temperatures. By lubrication, engine oil also serve as a coolant, reducing the heat emerging from an engine’s combustion chamber.
However, engine oil degrades as usage continues overtime. A former viscous and pale golden color fresh engine oil becomes thick, dark and dirty after prolonged usage resulting to an oil sludge. While in use, particles from dust, dirt and debris in the engine mixes with the engine oil leaving a dirty deposit in the vehicle’s engine which contributes to the sludge. Oil Sludge is known to clog engine parts, causing failure in the internal combustion engine which usually lead to total engine replacement. When engine oil is changed, automatically the sludge and other wear particles are removed. Contaminated oil can affect overall engine performance. This is why it is important to regularly change the oil. The generally accepted benchmark for changing engine oil is between 3000 to 5000 miles of usage in most vehicles. In California, 3000 miles or more is the recommended mileage for changing a vehicle’s engine oil.
Not changing a vehicle’s engine oil could result to some fatal engine failures and sometimes total engine breakdown. Changing it has a lot of advantages. New engine oil keep the cylinders firing properly and enhances engine performance making it economical to manage. This also increases the life span of the vehicle. Engine parts could corrode due to water condensation, a good engine oil will however prevent corrosion. Scheduled oil change minimizes a vehicle’s fuel consumption and improves gas mileage, hence increases fuel savings. It is known that most states conduct vehicle emission test to control the level of hazardous gases released into the environment, and every vehicle in such state must pass this test. Changing oil regularly reduces exhaust emissions especially in older vehicles enabling them to pass emissions test. Engine repair and replacement of damaged parts are very costly. Indeed, a lot of damages would be avoided by simply changing engine oil at the appropriate time. As the old saying goes, “A stitch in time saves nine”. It would be easier to change a vehicle’s engine oil than actually changing the whole engine due to negligence. Would you rather spend over $4500 yearly fixing engine’s problems resulting from bad engine oil or spend an average of $150 yearly to change your vehicle’s engine oil?
It is also important to change the oil filter on every oil change. The oil filter cleanses the oil. A bad filter is as risky as a bad oil. Rather than only changing oil, it is advisable to allow a certified mechanic change the engine oil as well as the oil filter.
