0w20 and 5w30 are ideal motor oils with low viscosity for all temperature conditions. Both of these oils are quite popular for all types of car engines. It is because the smoothness of oil flow is proficient in both these oils.

Also, changing your car’s oil helps the vehicle engine revive and stay active over time to lubricate and seal the critical parts. Therefore, choosing the best oil is important by knowing about the specifications and differences if you intend to increase the life of your car’s engine.

0w20 vs 5w30

Motor oil is preferably known as the power source for all forms of machinery, especially cars. However, if you do not change the oil at the right time, your vehicle engine will eventually take a heavy blow due to the accumulation of dirt and build-up of sludge.

Both 0w20 and 5w30 are pretty proficient in assisting the engine in motion but have some variations in their specifications. These specifications and differences can have a serious impact on vehicle performance.

To get an idea of those differences, follow this article that derives insight into 0w20 vs 5w30.

0w20 Specifications

0w20 is the best among these two oils, as it has lower viscosity in terms of both low and high temperatures. The viscosity at low temperatures is 0, and for high temperatures, it is 20. In addition, it is reportedly replicating better performance than most of the other motor oil types.

0w20 is specified as the multi-viscosity oil, as it consists of certain additives that are particularly of low viscosity when it is cold. Most cars are now undergoing replacement for their synthetic oil with 0w20 to ensure that engine performance is optimal with no adverse effects on the environment.

With 0w20, the losses in oil are minimum, especially during cold climates. It is an expensive oil but is worth the investment. It can help you improve the lifespan of your vehicle’s engine. Furthermore, it supports good start-up and low-temperature protection.

Not just that, but high-temperature protection is also better than 0w40, 5w30, 5w40, and other such competitor oil variants.

0w20 oil helps vehicle owners minimize fuel consumption rates and improve the efficiency of the engine. The machinery clearances within the engine need optimal lubrication, depending upon the stress imposed upon it.

So, whether you prefer taking your car on long rides or occasional rounds, you need engine oil to help the engine sustain continuous load exertion and keep the engine functioning when it is at rest for a long time. Also, 0w20 is essential to pump the car’s engine to revive from the cold climate.

5w30 Specifications

5w30 motor oil is yet another proficient product that carries the potential of helping the vehicle engine function, even in critical climatic conditions. Irrespective of whether you are driving or storing your car in a cold or hot climate, ideal engine oil like 5w30 has the power to help you pump it. In 5w30 oil, the oil’s viscosity is low at winter temperatures and is also optimized for high temperatures.

5w30 is multi-grade motor oil that is best for vehicles that intend to operate mostly at low temperatures. Moreover, it also functions well at high temperatures. Therefore, it is ideally efficient in fuel consumption to suppress the drag on moving parts of the engine. Also, they need much heat to avoid dysfunctional and hurting the car’s engine. Otherwise, you can use engine block heaters just to maximize oil flow.

5w30 motor oil is essential for heavy machinery, and it functions well even at a temperature low up to 35 degrees Celsius. This motor oil intends to restrict the friction possibilities over your engine. Furthermore, it is a thinner motor oil that is less expensive than 0w20 and is equally efficient with 0w20 in terms of quality.

0w20 vs 5w30

Car engine


  • 0w20 and 5w30 have a smooth engine flow that improves their reach.
  • 0w20 and 5w30 are both thin oils.
  • Both should be replaced after 10,000 miles.


  • The low-temperature viscosity is different in both the oils, 0 and 5, respectively.
  • The high-temperature viscosity is different in both the oils, 20 and 20, respectively.
  • Also, the price of 0w20 is higher than that of 5w30.
  • 0w20 offers better performance in low temperatures than that of 5w30.

Major Distinguishing Factors

  • 0w20 can pump the engine at the lowest temperature up to -40 degrees Celsius, whereas 5w30 can pump the engine at the lowest temperature up to -30 degrees Celsius.

When To Use 0w20?

0w20 is preferable for cars that are running mostly in cold climates. For example, if you own a diesel and gasoline engine vehicle and it halts mostly in cold regions, then 0w20 is the best pick. Even though 0w20 is an expensive alternative, it is an ideal choice.

Also, it would be best if you did not settle for cheap and ineffective oil. Instead, it is better to go for expensive but the best quality.

When To Use 5w30?

5w30 is considerably the best oil within an affordable range for all types of vehicles, especially light-duty petrol and diesel engines. Even though it has a higher viscosity than 0w20, it is still an efficient option for budget-restrictive people.

Apart from that, if your car runs a lot between two cities, and covers 10,000 miles quite too often, then frequent replacement might be too expensive with costly oils.

Therefore, 5w30 can be an ideal pick.

Final Verdict

It would be best to keep in mind that your vehicle manufacturer has specific details to help you decide the best oil. And, most of the brands will recommend you with either 0w20 or 5w30, as they are the best options in the lot.

However, they do have subtle differences that make one better than the other. So, pick an ideal one for the purpose. Both are best in their segments, and it depends upon you to choose the best as per your vehicle specifications.
