My Experience with SAE 15W 40 Engine Oil: A Necessity for Optimal Engine Performance
As a car enthusiast and frequent road tripper, I have learned the importance of using the right type of engine oil for my vehicle. After extensive research and testing, I have found that SAE 15W 40 engine oil is necessary for optimal engine performance.
First and foremost, SAE 15W 40 engine oil is formulated to provide protection to the engine in extreme temperatures. The numbers in its name refer to its viscosity rating, with “15W” indicating its viscosity at colder temperatures and “40” indicating its viscosity at higher temperatures. This means that the oil will flow smoothly through the engine even in cold weather, reducing wear and tear on crucial engine components. Additionally, it will maintain its thickness at high temperatures, preventing it from thinning out and losing its lubricating properties.
Moreover, SAE 15W 40 engine oil is designed to clean and protect the engine from harmful deposits. As an older car owner, I have personally experienced how sludge build-up can affect engine performance and decrease fuel efficiency. This type of oil contains detergents that help break down and remove any deposits or impurities
