Poor-quality engine oils can lead to fuel consumption and costly engine repairs.

Consider motor oil as cheap insurance for your vehicle. Oil protects engine parts and reduces friction between them—the less resistance in an engine’s components, the more power it provides and accelerates fuel economy. But what makes an engine oil better than the rest? Let’s explore this article.

How to Choose the Best Engine Oil for Your Vehicle?

While choosing high-quality motor oil is essential, it is sometimes challenging for uninformed automotive drivers to select the best oil for their vehicles. As a result, drivers often fall prey to brands presenting lucrative offers and claiming high quality at a lower price.

Consider the following things when choosing motor oil for your vehicle.

Vehicle Manufacturer & Series:

The first thing you should consider while choosing an engine oil for your vehicle is its make and model. Today, vehicles contain high-performance engines that improve efficiency and require engine oils with newer formulations to keep up with these upgrades. So, choose your motor oil according to your vehicle manufacturer and series.

Oil Standards:

While buying motor oil, look at its label. It consists of names of different oil standards followed by motor oil manufacturers. If your desired motor oil is certified with those standards, it meets the industry requirements. European Automobile Manufacturers Association (ACEA) and American Petroleum Institute (API) are the most popular oil standards.


Oil standards, including API and ACEA, offer different certifications for engine oil. These certifications guarantee the quality of engine oil and protection against wear. API Donut and API Starburst are two of the most authentic certifications that certify that the engine oil has these symbols that meet all the current oil standards and the International Lubricant Specification Advisory Committee (ILSAC) standards.

Viscosity Grade:

The viscosity grade measures the oil’s resistance to flow. It indicates the quality of the oil. The well-suited the viscosity index of the oil to the vehicle, the better it is considered.
