I have been a car owner for many years, and one thing that I have learned is the importance of using the right motor oil for my vehicle. One type of motor oil that I always make sure to use is 10 W 40. In this article, I will explain why I believe this type of motor oil is necessary and why it has become my go-to choice.

Firstly, 10 W 40 motor oil provides excellent protection for your engine. This particular grade of oil has a high viscosity, meaning it can withstand high temperatures and prevent engine wear and tear. This is especially important for older cars or vehicles with high mileage. As an engine ages, it becomes more prone to wear and tear, so using a thicker oil like 10 W 40 can help prolong its lifespan.

Secondly, 10 W 40 motor oil is versatile and can be used in both hot and cold weather conditions. The “10 W” in the name stands for its winter viscosity rating, meaning it can flow easily even in cold temperatures. This is crucial as cold weather tends to thicken motor oil, making it harder for the engine to start. With 10 W 40, you can ensure that your engine stays lubricated even during the coldest months.
