Fuel Economy: 5W-20 generally offers a 1-2% improvement in fuel efficiency compared to 5W-30. This directly contributes to better fuel economy, as the engine works less to circulate the lubricant.
Understanding the 5W20 vs 5W30 Viscosity Difference
The key difference lies in the final number: 20 versus 30. A 5W-20 has a lower viscosity, meaning it is thinner and flows more easily, while a 5W-30 is thicker and provides a more substantial oil film between moving parts.
In this context, the "5" in both grades means the oil flows well at low temperatures, typically offering reliable cold starts down to about -30°C or -22°F. Hot Weather Stability: 5W-30 maintains its viscosity better in extreme heat, reducing the risk of thinning.
Understanding the Viscosity Difference Between 5W20 and 5W30
Manufacturers recommend specific oil grades based on rigorous engine testing. Choosing the right motor oil is one of the most critical decisions for maintaining engine health and performance.
