Why I Believe SAE 15W 40 Engine Oil is Essential

As a car enthusiast and someone who has experienced firsthand the importance of proper engine maintenance, I strongly believe that SAE 15W 40 engine oil is necessary for optimal engine performance. Here are a few reasons why:

Furthermore, SAE 15W 40 engine oil has a higher viscosity index compared to other grades of oil. This means that it maintains its thickness and lubricating properties even in high temperatures, preventing metal-to-metal contact and reducing friction within the engine. This not only helps to prolong the life of the engine but also improves its overall efficiency.

In addition to its lubricating properties, SAE 15W 40 engine oil also contains additives that help to clean and protect the engine. These additives work to prevent build-up of harmful deposits and sludge, which can impede
