Difference Between 0W-20 and 5W-20 Oil

As a resident of Calgary, Alberta, you’re no stranger to the extreme temperature fluctuations that our region experiences throughout the year. From bitterly cold winters to hot summer days, choosing the right motor oil for your vehicle is crucial to ensure optimal performance and engine protection. Two popular motor oil viscosity grades are 0W-20 and 5W-20, but what’s the difference between them, and which one should you choose for your vehicle?

Viscosity Explained

The numbers and letters in motor oil viscosity grades refer to the oil’s ability to flow at different temperatures. The “W” stands for “winter,” and the number preceding it indicates the oil’s viscosity (thickness) at low temperatures. The lower the number, the better the oil flows when it’s cold.

The second number represents the oil’s viscosity at higher temperatures. For example, in 0W-20 oil, the “0W” means it has excellent cold-temperature flow properties, while the “20” indicates its viscosity at operating temperatures.

0W-20 Motor Oil

0W-20 is a low-viscosity, fully synthetic motor oil designed for modern, fuel-efficient engines. Its primary advantages include:

1. Superior Cold-Start Protection: The “0W” rating means this oil flows exceptionally well in cold temperatures, ensuring rapid lubrication of critical engine components during start-up, even in Calgary’s harsh winters.
2. Improved Fuel Economy: The low viscosity of 0W-20 oil reduces friction within the engine, resulting in better fuel efficiency compared to thicker oils.
3. Reduced Emissions: Lower friction also translates to lower emissions, making 0W-20 a more environmentally friendly choice.

However, it’s important to note that not all vehicles are compatible with 0W-20 oil, so always consult your owner’s manual for the recommended viscosity grade.
