With the recent changes in gas prices, many people are wondering what kind of oil they should be using in their car. There is a lot of debate on whether to use 0w20 or 5w20 synthetic oil. Let’s take a look at both types and see which one will give you the best performance for your vehicle.

What Do These Oil Numbers Mean?

The “w” in the oil number stands for winter. That means both 0w20 and 5w20 Synthetic Oil are suitable for the colder area. The “20” refers to the viscosity of the oil when it’s at 0°C. The lower the number, the thinner the oil. 0w20 is thinner than 5w20 for example.

The “20” in the number is just a reference point. The oil will still be viscous at higher temperatures, it’s just that it will be thinner than at 0°C. The “5” in the number would refer to the viscosity of the oil when it’s at 5°C. The higher the number, the thicker the oil.

This is a way to tell how thick the oil is. The viscosity of 0W20 oil changes from 0 in cold temperatures and 20 at the operating temperature. 5W20 oil has a viscosity that changes from 5 in cold temperatures.


Why Compare?

The main difference between 0w20 and 5w20 is that 0w20 is thinner at colder temperatures. Both are suitable for low-temperature use, but 0w20 has the advantage of being more fuel-efficient especially when it is cold.

However, 5w20 is suitable for most areas with an average temperature of around 10°C. And the difference in viscosity between 0w20 and 5w20 at certain temperatures is almost non-existent.

The next thing to consider is the climate you live in. If it’s cold, the 0w20 will flow easier and provide better performance. If it’s hot, the 0w20 will thin out and provide less protection for your engine. On the other hand, 5w20 oils are best for the warmer climate because they will resist thinning out as much as the 0w20. You should also consider how often you drive. If you’re on the highway a lot, then go with the 0w20 because it will provide better fuel economy.

Check Car Manual

The first thing you can do is check your car manual to see which viscosity you can use in this vehicle. You might have to search through the manual, but it’s worth doing because your car manufacturer is going to know what oils are best for their vehicle.

When you get the right oil, then your car is going to run smoothly and last much longer. If both viscosity allows use then use them alternately without any hesitation.

Fuel Economy

The fuel economy is one of the biggest factors for people when choosing their oil. The 0w20 will allow your engine to reach maximum efficiency, but it will only last for a few thousand miles. The heavier oil, the 0w20 is thinner than other oils and it provides less protection to your engine. It is better for newer engines and works best in colder climates.

On the other hand, 5W20 is a type of oil that is best for winter. It can save fuel and it provides the best fuel economy, with a 10W-30 as an alternative for higher temperatures. In the end, both types of oils are great for fuel economy but you need to determine how often you will be driving and in what climate to find the best fit for your car.


Another most important thing you need to consider than where do you live in. Because both 0w20 and 5w20 Synthetic Oil are made for different climates. The 0w20 is made for colder climates and it will give you better fuel economy, but the protection won’t last as long as the 5w20.

On the other hand, if you live in a warmer area and it is between -35°C to 20°C most of the time then the best option for you will be the 5w20 Synthetic Oil.

Performance Level

0w20 Synthetic Oil is also a good choice if you live in an area that has harsh winter conditions or if your engine doesn’t have the latest technology. The thicker oil will provide more protection against cold and it can save on gas mileage because of its better lubricating properties.

5w20 Synthetic Oil is also a good choice for people who want the best performance and fuel economy. It is made to resist thinning out in high temperatures and it has better shear stability than the 0w20.

Is 5w20 Full Synthetic?

Yes, the motor oil is completely synthetic. It is specially created to protect the engine and keep it neat. The oil enhances the cleanliness of the engine and provides a noteworthy increase in performance.

The oil is initiated from high-quality synthetic stocks following a very specific additive component system giving maximum priority to the performance. This product already met and surpassed the performance standards set by the industry.

How Many Miles Is 5w20 Oil Good For?

Being made of advanced synthetic formula, this oil does not tire out that easily. It goes on and on even when the temperature is lower and gives significant protection to the engine. The benefits of being fully synthetic come into play when we measure stability and mileage. Magnificent oxidation and stability ensure that the vehicle is protected for at least 10,000 miles before any talk of the oil change.

What Car Use 5w20 Oil?

This product is suggested for use in any gasoline-powered vehicle. By gasoline-powered means, it can be used in SUVs, Small trucks, Vans, passenger cars, and in turbocharged high-performing vehicles.

The presence of Viscosity in a car engine is a vital thing to consider before using the oil. But it is not wise to use in a two-wheeler or engines designed to fly aircraft unless recommended by the builder.

What Happens if I Put 5w20 Instead of 5w30?

The viscosity of the oil is different in each model. The higher the number says on the label, the higher the thickness of it. The fuel consumption may increase due to the change in the fuel.

The manual provided with the car has a list of acceptable weights by the temperature. But if you hear a chattering sound on the valves, it is wiser to switch back to the recommended one. Unless you are using the vehicle in extreme weather like too hot or too cold, you are good to go.


If you have a modern engine and you live in the northern US, then 0w20 is the best choice for your car. It will provide the best fuel economy and engine protection. If you have an older engine or you live in a warm climate, then the best choice for you is the 5w20 Synthetic Oil, but more fuel-efficient, In the end, you need to decide which oil is best for your needs and your car.

Frequently Asked Questions (FAQ)

Synthetic oil 0W20 is designed to last longer than conventional motor oil. It can typically last for up to 15,000 miles or one year, whichever comes first. Check your car’s owner’s manual to see what the manufacturer recommends for your specific vehicle.

0W20 synthetic oil is a high-quality motor oil that can provide superior protection and performance for your vehicle. This type of oil can help improve fuel economy and reduce emissions, while also reducing wear on engine parts. If you are looking for top-quality motor oil, 0W20 synthetic oil is a great option to consider.

5w20 oil is a type of motor oil that is often used in vehicles with smaller engines. This oil is thinner than other types of motor oil, which helps to improve fuel economy and reduce emissions. Additionally, 5w20 oil can help to extend the life of your engine by reducing wear and tear.
The answer to this question depends on the motor oil brand and formulation. For example, some motor oils marketed as “full synthetic” may contain a higher percentage of synthetic base oil than others. Additionally, some brands may add different additives or other ingredients to their synthetic blends, which can affect the overall properties of the oil. As such, it’s best to consult your owner’s manual or the manufacturer of your motor oil to determine whether 5W-20 is a full synthetic or synthetic blend.
