Why 5W 40 Diesel Oil is Necessary?
As a diesel engine owner, I have always been advised to use 5W 40 diesel oil for my vehicle. At first, I was skeptical about the necessity of this specific type of oil, as I thought any type of motor oil would suffice. However, after doing some research and consulting with experienced mechanics, I realized the importance of using 5W 40 diesel oil for my engine.
Firstly, the number 5 in the oil’s viscosity rating (5W) refers to its ability to flow easily at low temperatures. This is crucial for diesel engines as they tend to produce more heat and require an oil that can maintain its viscosity even in extreme temperatures. In colder climates, using a thicker oil can cause it to become too viscous and prevent proper lubrication, leading to potential engine damage.
Moreover, the number 40 in the viscosity rating (40) refers to the oil’s thickness at high temperatures. Diesel engines operate at higher temperatures than gasoline engines, so using an oil with a higher viscosity rating helps maintain proper lubrication and protects against wear and tear. This is particularly important for heavy-duty vehicles such as trucks and buses that frequently carry heavy loads.
