5w40 VS 5w30 – Main Differences

Before we reach to the answer of “Can I use 5w40 instead of 5w30”, you need to know the major differences between these two. So, here are those main differences.

Viscosity

The main difference between 5w30 and 5w40 is the viscosity. 5w30 is a thinner oil and is better for fuel economy, while 5w40 is a thicker oil and is better for engine protection. 5w30 has a lower viscosity than 5w40, which means it flows more easily and is better for fuel economy. 5w40 has a higher viscosity, which means it flows more slowly and is better for engine protection.

5w30 is better for use in cold weather, while 5w40 is better for use in hot weather. 5w30 is also better for use in low mileage engines, while 5w40 is better for use in high mileage engines. 5w30 is synthetic oil, while 5w40 is a synthetic blend. 5w30 is also available in higher viscosities, such as 10w30 and 20w30. 5w40 is not available in higher viscosities.

Adaptability

Another difference between these two is their adaptability. 5w30 is a synthetic blend whereas 5w40 is a full synthetic. 5w30 is also more lightweight than 5w40, meaning that it is easier for your engine to turn over in cold weather. 5w40 is better for high performance engines and extends the life of your engine by protecting it against wear and tear.

5w30 is more adaptable to a wider range of temperatures than 5w40, making it a better choice for most drivers. 5w40 is better suited for extremely cold or hot weather conditions. If you live in an area with extreme temperatures, you may want to consider using 5w40 in your vehicle.

Temperature

Temperature also plays a big role on both these two. 5w30 is designed to be used in lower temperatures, while 5w40 is designed to be used in higher temperatures. This is because 5w30 has a lower viscosity, which means it is thinner and flows more easily in lower temperatures. 5w40 has a higher viscosity, which means it is thicker and flows more slowly in higher temperatures.

5w30 is also lighter weight oil, while 5w40 is a heavier weight oil. This means that 5w30 will flow more easily and be less likely to cause engine wear in lower temperatures. 5w40 will flow more slowly and be more likely to cause engine wear in higher temperatures.

Can I use 5w40 instead of 5w30? – The Answer
