Can you use 5w30 instead of 0w20 oil? Every motor oil is multigrade oil. However, 0w20 and 5w30 are well-known for their outstanding achievements. Many individuals are unsure whether they can use 5w30 oil instead of ow20 oil.

The simple answer is Yes, instead of 0w20, you can use 5w30. You won’t notice any significant differences, however, you will see a performance decline while using 5w30 in extremely cold weather.

Oil Viscosity

Because it is accountable for friction and heat generation in cylinders, gear sets, and bearings, motor oils are always evaluated according to their viscosity.

The viscosity lubricates the vehicle’s moving parts, allowing them to move smoothly. Temperature fluctuations have a substantial impact on its viscosity. Temperature is proportional to it. The viscosity increases as the temperature rises and the viscosity of the motor oil decreases as the temperature falls.

The motor oil compatible with your car is one that performs well at extremely high temperatures and does not modify the flow when the temperature falls below freezing. 5w30 is frequently used because it flows better in cold or hot climates.

You won’t notice any significant differences, however, you will see a performance decline while using 5w30 in extremely cold weather.

It also depends on the timing of the variable valves (VVT). If your vehicle’s engine has variable valve timing (VVT), it’s best not to adjust the weight and stick to the manufacturer’s recommendations.

Most contemporary engine models have this function, which necessitates the use of thinner oil. Because the VVT mechanism functions better in thinner oil than in heavier oil, it is advised that you use it at the appropriate weight.

If you have a newer car, it’s recommended to use the 0w20 next time. If you own a 2010 or newer vehicle with less than 40,000 miles, it is suggested that you do not use 5w30.

0W20 vs 5W30

Motor oil 5W30

5w30 is a popular oil for petrol and diesel engines in small sedans and light automobiles. It has the extraordinary ability to flow readily with a viscosity grade ranging from 5 to 30 and is completely capable of serving efficiently.

The motor oil is designed for usage in winters, as the name implies, and the lowest viscosity level it provides is 5, while the highest is 30.

Motor oil 0W20

The low viscosity of this oil allows it to run freely through the engine. This oil is becoming well-known in the industry due to its outstanding performance.

In winters or freezing conditions, 0w20 oil has a viscosity grade of 0 as the name suggests. Similarly, when the temperature rises above 20 degrees, the viscosity of the oil rises to 20.

During the winter, the oil functions admirably by effectively moving through the engine and boosting the vehicle’s performance. Furthermore, this oil decreases engine waste, thereby saving the environment.

Key Differences

  • Weather

The ambient temps will determine whether it will produce a better effect or not. If you shelter in a hot climate, a 30 weight oil will give you a better outcome, but if you live in a colder climate, you’ll see a tiny performance loss if you use 5w30 instead of 0w20.

  • Fuel Economy

Because 0w20 is noted for its excellent fuel economy, you will notice a slight increase in fuel consumption when using 5w30.

Can I Mix 5W30 With 0W20?

Yes, you can blend 5w30 and 0w20, but you should choose 5w30 synthetic oil instead of ordinary oil.

Because 0w20 motor oils are either wholly synthetic or partially synthetic, they will void your car warranty if you have one.

When Is It Appropriate to Use 5W30?

Make sure the oil you’re using is right for your vehicle before you put it in. Consider your owner’s manual for this reason.

5w30 is a multi-grade oil that can be utilized in temperatures ranging from 35 to -30 degrees Celsius. This feature makes the oil an excellent choice if your area has a lot of seasonal variances. The motor oil 5w30 is designed primarily for use in cold weather.

Typically, oils designed for use in low temperatures are not suitable for use at high temperatures. When used in warmer temperatures, however, 5w30 functions admirably. Whereas most oils have viscosity grades of 10 or 15, 5w30 has a viscosity rating of 30 which is ideal for your engine.

As a result, it is capable of safeguarding the engine and its components. When traveling long distances, oil is also beneficial. It enhances fuel efficiency by lowering consumption and allowing you to get more miles.


Apart from viscosity rating, there are additional aspects to consider while choosing motor oil. Cost, climate, vehicle age, and engine condition are all factors to consider.

The power of your car will not be significantly affected if you use 5w30 instead of 0w20. Your car will continue to perform smoothly and provide you with a pleasant journey.
