Will Conventional Motor Oil Hurt My Car? The Truth

Conventional oil is a type of motor oil widely used in vehicles. Derived from crude oil, this motor oil performs well across numerous applications.

It is also cost-effective and widely accessible, providing improved lubrication as well as protection from wear and corrosion making it a great option. So, as you can see, there is no need to worry about conventional oil hurting your car.

What is Conventional Motor Oil?

Motor oil is the liquid responsible for lubricating, segregating and protecting metal parts inside an engine. This task is accomplished through its complex properties such as viscosity (the degree of resistance to flow) and stability at both high and low temperatures.

Conventional motor oil is composed of a blend of petroleum hydrocarbon base oils and additives designed to enhance certain performance characteristics. These additives reduce wear, friction and oil oxidation for extended engine operation at reduced emissions.

These oils contain special additives to safeguard high-mileage vehicles against leaks, corrosion and other signs of aging. Furthermore, they help prevent oil combustion in a fuel system.

Will Conventional Motor Oil Hurt My Car?

No you don’t necessarily have to worry about conventional motor oil hurting your car because it won’t. This motor oil is made from crude oil through distillation. This process uses heat and pressure to separate different hydrocarbons.

It is safe to say that conventional oil is an economical lubricant that will coat the crucial parts of your engine that run at high speeds and protect them against wear.

However, the biggest downside that comes with this motor oil is the fact that it breaks down faster than synthetic oil and leaves behind carbon deposits in your engine – known as “engine sludge.” With continued usage, conventional oil may begin to break down too quickly for optimal protection against these effects.

Is Conventional Oil Better For Your Car?

Conventional oil is considered to be one of the most popular engine oils on the market used in automobiles due to its long history of reliable performance.

Conventional oil, in addition to being a fossil fuel, contains additives that lubricate engines and reduce wear on critical engine parts. These additives include detergents, viscosity modifiers and other compounds designed to keep your engine functioning optimally under various conditions.

However, the older and more worn out your engine is, the less reliable conventional oil can be. In this instance, synthetic high mileage oil or a synthetic blend might be more suitable.

How Often Do You Have to Change Conventional Oil?

When it comes to changing oil, the answer depends on the type of oil you use, your driving habits and even the engine that powers your car. Generally, it’s recommended that you change your oil at least every three months or 3,000 miles.

Due to advances in engine efficiency and oil chemistry, engine oil change intervals have been extended from 5,000 to 7,500 miles depending on the make and model. Some vehicles feature an instrument cluster information screen that displays remaining oil life as a percentage, as well as dipsticks for manual inspection.

However, going beyond the oil-change recommendations in your owner’s manual will only cost you money and put more strain on the environment. Indeed, changing oil more frequently than necessary is a common issue that environmentalists say is contributing to an oversupply of waste oil that must be disposed of.


If you’re searching for the most cost-effective, popular and dependable engine oil available, conventional motor oil may be just what the doctor ordered. However, many drivers have doubts about this type of oil and whether synthetic lubricants are really better for their cars.

Utilizing conventional oil in your vehicle is one of the best ways to extend its life and protect its essential parts. According to the American Petroleum Institute, using conventional engine oil with appropriate additives will keep your car running smoothly and safely for many years into the future.
