0W20 Vs 5W20 Synthetic Oil – Battle of Oil King in Winter Regions


0W20 Vs 5W20-this now seems more hyped in case of oil choosing in the polar region. Are you also lingering between these two?

Both of these oils provide almost the same features. But still there remains a debate between these two because of a slight change. And this negotiable difference makes people fall in confusion.

So, here we will give you a complete idea of the two. After reading it, you can easily choose which oil you should use in your engine.

A Total Comparison of 0w20 Vs 5w20

Have a glance at the comparison table of 5W20 Vs 0W20.

0w20 Oil

5w20 Oil

Regional Suitability
Perfect for extreme Winter region. This oil is perfect for the engine where there is standard hot to too cold weather.
In terms of economy, 0Ww0 oil is proven economical far now. 5w20 is preferable but a little frugal.
Additional Criteria
This oil is perfect for a high-performing engine car. It ideal fo the general regular purpose cars.
Vehicle Compatibilities
Any gasoline or hybrid engine cars like Corolla, Toyota, run fine with 0w20. Any passenger cars, small trucks, vans, and SUVs go well with 5w20.
In Case of Price
Seems a little bit expensive cheaper comparing to 0w20

0w20 Vs 5w20 -Are There Any Similarities

If you want to know about the similarities, then both are the same on most sides. Both oils are synthetic entirely. And both the oils are for winter regional usage purposes.

To explain further, W-here stands for ‘winter’ to some and ‘weight’ to some. But to ensure, W mainly describes the viscosity level of the oil. Oil viscosity refers to the resistance or consistency offuel in time of flowing through the engine parts. In winter regions, this viscosity type matters a lot for engine oils.

This viscosity level decides how the oil will flow as the engine parts’ lifetime depends on the lubricated flow of oil.

The number before and after W indicates the oil’s temperature when the engine is in the cold and running phases. At a time, it also defines the viscosity level.

0W20 Oil – Explained

Here, the number 0 represents that the viscosity or the oil’s consistency is 0 when the engine is in cold position. And the 20 indicates the viscosity level on the running temperature of the engine.

Consistency at Low Temperature

The viscosity of the oil is essential when it flows. And based on this feature, you need to choose oil for your car. Oil is the lifeline of any vehicle. It makes the engine run and plays a vital role in keeping the engine parts collision-free and running smoothly.

So, if you’re using 0w20 motor oil, the viscosity will be 0 as well as having 0 weight. As a result, it flows with less consistency in engine startup time, which is much useful for the engine gears.

Consistency at High Temperature

Again, the number 20 indicates the viscosity level when the engine raises to its maximum temperatureof running. Here, this oil flows with as lubricants as the oil with a weight of 20.

It is shown in many statistics that 0w20 oil is the best oil ever for its lower viscosity. It remains such thin in the startup that does not let the engine having any friction.

5w20 Oil – Explained

In 5w20 synthetic oil, it defines the same as the 0w20 oil; only the viscosity level is more extensive in the engine’s startup. If the motor is for high-performing riding use, then this viscosity can harm the engine components.

Consistency at Low Temperature

In the lower temperature, that means when the engine is cold, 5w20 oil flows with a thickness of level 5 and five weight of circulating consistency.

Generally, oil gets thinner when the temperature rises. But in the wintery areas, the lower the fuel’s viscosity, the longer the life of the engine will be.

Consistency at High Temperature

At the running temperature, it means when the engine reaches its maximum temperature, 5w-20 oil remains the consistency of 20. And it is fear enough for the auto parts.

Now, many may be thinking, why people use 5w20 then? Some cars recommend the oil types. According to that, some wish to have that recommended type of engine oil.

Again, for a general-purpose car, this 5w20 motor oil works perfectly with ideal lubricants inside. Apart from this, 5w20 motor oil is less expensive compared to the 0w20 one.

More About 0w-20 Oil

If you’re lingering between 5w20 vs 0w20 then, check out the pros and cons of the two. You can be surer of these two motor oils.


  • Ideal viscosity level when the engine is cold
  • Low collision system provides more fuel economy
  • Does not let build-up any foam or friction in the flow of the oil
  • Completely protects the engine parts from having corrosion
  • No need for changing oil in between 1000 miles
  • Perfect motor oil for wintery regions
  • Provides your car with the lowest oil consumption but highest performance benefits
  • Ideal to use in hybrid engine vehicles, Toyota, Corolla, BMW, etc.


The cons of this oil do not mean very negative sides. It will help you to select your preferred criteria for the oil.

  • Little bit expensive
  • Won’t be economical to use on general passenger car
  • Not usable in the regions other than wintery

More about 5w-20 Oil

Let’s have a view on the amenities of 5w-20 oil. Though it does not have many differences than the 0w-20 oil, you can make yourself sure.


  • Comparatively cheaper than 0w-20 oil
  • Perfect for the regular basis usage purpose
  • Provides a moderate resistance when it flows
  • Will be ideal to use in the region of cold to warmer
  • Cab be used in the more temperate regions
  • It consumes more fuel if mot used on the recommended engine


Here, the cons are mainly the features that do not go with 0w-20 oil. So, let’s see and differentiate between these two oils.

  • Little high viscosity can damage the motor parts on the startup time
  • Not preferable for too cold regions
  • Not usable on high-mileage vehicles

The Answer: Can You Mix 0w20 and 5w20?

0w-20 motor oil is highly recommended for cold areas. It helps the engine to start with the lowest viscosity that defines the smallest resistance in flowing.

On the contrary, 5w-20 oil is also for a cold region basis. But it is ideal for less performing engine cars. In the term of mixing two, you should check your car’s manual at first. And it’s a must thing you need to do.

If there you find allowance for using 5w-20 oil, then you can go with your mixing. But if it does not, then it’s a big NO. Some car engine has a limited heat endurance capacity. So, if you use more than its ability, it may damage the parts that create corrosion.

0w20 Vs 5w20- Fuel Economy Goes Where More

0w-20 oil gives you the highest fuel economy. It is a 100% full-synthetic oil. And as synthetic oil, it has the lowest viscosity, which you can assume as no consistency.

So, with the rise of temperature, the oil gets thinner similar to watery. And it does not let build any collision among the components. So, for the least fuel consumption, 0w20 oil gets a high Clap.

Frequently Asked Questions(FAQs)

Is 0w20 Oil Safe?

Of course, it is!
0w-20 oil provides you an engine running with the lowest resistance when it is just getting started. And up to the heating of the engine, this oil keeps its most moderate resistance. Consequently, you get the ultimate low viscosity, even on the highest temperature of the engine.
So, it’s safe for the engine, in fact, a savior for the engine parts.

Can I Use 5w20 Instead of 0w20 Subaru?

Well, this seems a little bit confusing, though. But the fact that you need to consider first is your vehicle allowances for engine oil.
In earlier times, people used to change oil with the season. Because of not getting a clear assurance, people used 0w20 oil in winter and 5w20 or 5w30 in the summer.
But nowadays, car engines are being made more advanced and fuel economical. If you are sure that your Subaru engine goes on high mileage every time and you stay in the cold areas, it would not be best to use 5w20 instead of 0w20.
0w-20 oil has the least resistance in flowing so, and it can be much thinner at high temperatures. As a result, it helps to keep the parts damage-free always,
But if you use 5w-20 oil here, you may end up your vehicle having friction among the parts within months.

5w-20 vs 0w-20: Which One You Should Choose?

We have discussed the facts of the two engine oils. You can now decide you will go with what depending on your region weather, vehicle usage type, and user manual.
But still, if you want to have a try by exchanging oils in your car, then it’s totally up to you to take the risk.

Final Verdict

If you are looking for some clear basics on 0w20 vs 5w20 then, this context has an overall discussion. You will get the amenities and drawbacks also.
