Does 5W40 Oil Increase Oil Pressure in Vehicles?

Learn how using 5W40 oil can affect oil pressure and engine performance compared to lower viscosity oils.

30 views

Using 5W40 oil can increase oil pressure compared to a lower viscosity oil like 5W30, especially in high-temperature conditions. The higher viscosity maintains a thicker oil film between moving parts, leading to increased resistance and thus higher pressure. However, it's essential to follow your vehicle's manufacturer recommendations to avoid potential engine damage or warranty issues.

FAQs & Answers

  1. What is the difference between 5W40 and 5W30 oil? The main difference is viscosity; 5W40 is thicker, providing better oil pressure in high temperatures compared to the thinner 5W30.
  2. Can using the wrong oil viscosity damage my engine? Yes, using oil with incorrect viscosity can lead to poor lubrication and potential engine damage, impacting performance and longevity.
