Which Is Heavier 5W20 Or 5W30 – Understanding Viscosity For Optimal Performance
When comparing 5W-20 and 5W-30 engine oils, the term “heavier” is a common misconception; neither oil is physically heavier in terms of weight per volume. Instead, these numbers refer to their viscosity, which is a measure of their resistance to flow. Understanding viscosity is crucial for selecting the correct oil, ensuring your engine is properly…
