Can I Use 0W20 Instead of 5W20?

If You Ask, Can I Use 0W20 Instead of 5W20? Then the straight answer is yes! But you should always use the right engine oil according to OEM recommendations, car & environmental conditions.

So we all should know about the right oil grade selection for our car. Here we will discuss the most popular oil grade, 0W-20 vs 5W-30, and the most popular topic, Can I use 0w20 instead than 5w20?

0W-20 & 5W-20 both motor oils are multigrade, infrequently used as winter viscousness oils, and have a comparable, adaptable operating temperature. Once selecting 0W-20 or 5W-20, you should understand their area unit’s critical variations. However, upon closer investigation, you will see the following slight differences:

can you use 0w20 instead of 5w20

0W20 vs 5W20

First of all, you need to know the difference between 0W20 & 5W20. Let’s discuss this regarding some important factor


You will see different viscosity variations of 0W20 & 5W20 oil in different temperature conditions. Let’s discuss in brief:

  • In the cold:

The viscousness of associated oil may be a life of its resistance to flow. It conjointly relates to the thickness of the oil at numerous temperature settings. At low temperatures, 0W-20 oil behaves equally to SAE 0W-weight oil. 5W-20 oil, on the other hand, functions as an associate SAE 5W weight oil. The lower quantity preceding the ‘W’ increase the oil performance, especially in viscosity. So, 0W20 may be an abundant agent oil than 5W-20. It’s additionally stable at low temperatures and flows additional simply through necessary engine components. 5W-20 may be a viscous oil with the following viscousness ideal for average operation temperatures starting from -22°F to 68°F. 

  • In the Hot:

0W-20 & 5W-20 both oils perform as associate SAE 20-weight oil at hotter temperatures. They need cheap fuel consumption, resulting in superior fuel potency, whereas lubricating all of your engine’s essential components. Each of those grades performs commendably in terms of operating temperature varying up to 68 °F. They don’t have issues with oil burning or exploitation of excessive oil even once the pressure level is high, so the temperature is high. 


Both 0W-20 and 5W-20 area unit agent oil grades operate best in weather conditions. 0W-20 oil is suitable for cold starts. It conjointly keeps sludge accumulation, engine wear, varnish deposits, and low-pressure levels cornered. With 0W-20, you will anticipate faster oil circulation and a drum sander flow. So, if you travel plenty in subfreezing and rarely in hotter temperatures, the 0W-20 oil grade is superb for you. 5W-20, on the other hand, includes a larger viscousness and works somewhat higher in seasonal environments. It is a slightly thicker oil that resists oil cutting at higher temperatures. Some vehicles will use each 0W-20 and 5W-20 oil. However, before you turn to a particular viscosity grade, sit down with your mechanic regarding what oil is best for your automobile. 

Fuel Economy: 

Regarding mileage and fuel economy, each 0W-20 and 5W-20 oil perform almost equally.0W-20 oil might give higher fuel economy and lower carbon emissions. However, it also depends on whether you use traditional, semi-synthetic, or entirely synthetic motor oil. Full synthetic 0W-20 and 5W-20 motor oils provide optimal fuel efficiency and economy.


There is nothing special to say about 0W-20 vs. 5W-20 price, As 0W-20 is more stable in a variety of temperature ranges & made from Group IV base oil, so in most cases, 0W-20 is more costly than 5W-20; on the other hand, 5W-20 sometimes would be synthetic blend oil which might be competitive price than 0W-20. However, it varies for oil suppliers and brands.

0W20 instead of 5W20?

Now come to the final point. I think you already understand that you can use 0W-20 instead of 5W-30 because 0W20 will give a smoother performance than 5W20 in low-temperature conditions and the same performance in adaptable temperatures. But in case of hot weather 5w20 can give more mileage, which already we discussed. And last thing you may have to pay more in case of using 0W20 instead of 5W20.And sometimes you will not avail of the warranty facilities due to using different viscosity, so before adding 0W20 instead of 5W20 you must ensure that the previous & new oil both are from the same brand.


Q. What can I use instead of 0W-20 oil?

As 5W-20 has the same viscosity level as 0W-20, you can use it easily if 0w-20 is unavailable near you. Some other fully synthetic oil like 5W-30 or 0W-30 also can be used for emergency cases. These are also thinner oil, almost similar to 0w20. But mind it, your first choice of oil grade must be according to your manufacturer’s guidelines.

Q. What is 0W-20 oil used for?

0W-20 is a synthetic oil mainly used for the latest model petrol & gasoline cars. It is perfect for use mainly in colder weather. This oil should not use in high-temperature conditions or two-wheeler vehicles like motorcycles or aviation vehicles.

Q.Is it okay to mix 0W-20 and 5W-20 oil?

It is typically not a good idea to mix various viscosity-grade oils.

SAE 0W oil, for example, is always synthetic. 5W-20 oil might be an artificial, synthetic mix, or conventional. Even if both of your oils are synthetic, combining them may cause your car’s fuel economy and efficiency to suffer.

It’s also conceivable that your 0W-20 and 5W-20 lubricants include incompatible additives, such as viscosity modifiers and corrosion inhibitors. As a result, it’s better to avoid mixing or combining them.

Q. Can I use 0W20 instead of 5w20 in my Ford?

First, you need to check the manufacturer’s manual, then if 0W-20 oil’s API grade matches you can use it instead of 5W-20. But in some cases especially for the 2020 F-150 Owners manual recommend 5W-30 or 0W-30; in that case, you should try for the exact oil.

Last Thoughts

0W-20 and 5W-20 are low temperatures, low-viscosity oil types that are rapidly supplanting others in favor. This is owing to its wide working temperature range and various advantages, including improved fuel economy.

However, before making the transition, be sure the oil grade is acceptable for your vehicle. It is critical to use the proper oil viscosity for engine life. In addition to normal maintenance and repair!
