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. However, it is important to balance fuel economy with engine protection, especially in vehicles that have been designed to operate with a slightly higher-viscosity oil.

Both share the same cold-start viscosity rating, which means they flow well in low temperatures, but they differ significantly in their performance at operating temperature. Making the Right Choice for Your Vehicle.
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. The “5W” part indicates that the oil behaves like a 5-weight oil when cold, which helps it circulate quickly during startup, reducing wear on critical engine components.

5W-20 is designed to be more fluid, which reduces friction and allows the engine to operate more efficiently. 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.
