Why Engine Oil SAE 15W-40 is Necessary?

I have been a car owner for several years now and one thing that I have learned is the importance of using the right engine oil. SAE 15W-40 is a type of motor oil that I have been using for my car’s engine and I can confidently say that it is necessary for several reasons.

The “15W” indicates its ability to flow smoothly in colder temperatures, while the “40” signifies its stability and protection in higher temperatures.

Moreover, SAE 15W-40 oil contains additives that help clean and protect the engine from wear and tear. As the engine operates, metal parts rub against each other causing friction and heat. This can lead to damage if not properly lubricated. The additives in this type of oil create a protective barrier between these moving parts, reducing friction and preventing premature wear.

Additionally, SAE 15W-40 oil also helps improve fuel efficiency. When the engine is properly
