Why Engine Oil SAE 15W-40 is Necessary?

As a car owner, I have learned the importance of using the right type of engine oil for my vehicle. One type that I have consistently used is SAE 15W-40. This particular grade of engine oil has proven to be essential for keeping my car’s engine running smoothly and efficiently.

First and foremost, SAE 15W-40 is necessary because it provides excellent protection for my car’s engine. The ’15W’ in the grade indicates the oil’s viscosity at low temperatures, making it easier to flow through the engine during start-up. On the other hand, the ’40’ signifies its viscosity at high temperatures, ensuring that it maintains proper lubrication even under extreme heat conditions. This balance is crucial in preventing engine wear and tear, which can lead to costly repairs.

Moreover, SAE 15W-40 also helps to improve fuel efficiency. A well-lubricated engine can run more smoothly and with less friction, resulting in better gas mileage. This not only saves me money on fuel costs but also reduces my carbon footprint by reducing emissions from my vehicle.

Another reason why SAE 15W-40 is necessary is its ability to
