Understanding the Basics of 5W-20 and 5W-30 Oil The numbers in a motor oil grade, such as 5W-20 or 5W-30, refer to the oil’s viscosity, or its resistance to flow. A 5W-20 oil is thinner at operating temperature than a 5W-30, which means it provides less resistance and can improve fuel economy.

Using a thicker oil like 5W-30 in these engines could potentially lead to reduced fuel efficiency, increased internal resistance, or even improper lubrication if the oil is not certified for the vehicle. Drivers in hotter climates or those who frequently operate their vehicles under heavy loads or high temperatures may also benefit from the additional thermal stability provided by 5W-30.
This difference in high-temperature viscosity plays a key role in how each oil protects your engine under various conditions. When 5W-30 Might Be the Better Choice There are situations where 5W-30 is a more suitable option, particularly for older vehicles or engines that have accumulated mileage over time.
