0W20 Vs 5W20: Which Is The Best Oil?

Just like you need food to stay active, the truck engine needs oil to operate well. And when it comes to motor oil, the one giant debate pops up which is 0w20 vs 5w20 winner.

To pick a side, you’ll need to think of the practical usage, performance, and other differential traits. One visible contrast which I spot is that the 0W20 performs better than 5W20 in the cold state.

Apart from this single variance, there are more that might surprise some. Let’s discover them now!

0W20 Vs 5W20

Comparison Of The 0W20 Vs 5W20 Oils!

To understand the winner of the 0W20 oil vs 5W20 oil debate, it’s essential to look into the direct traits that make them individual. So, I’ll mention all the differences and compare them side by side for you to know them better. Enjoy!


Using both motor oils will give a diverse feel in hot and cold applications. You can catch the difference once you are familiar with the letter and number meaning.

In short, the ‘W’ word indicates the oil weight and its left-side number (0 or 5) indicates the flowing level in cold temperature. The right-side number indicates the viscosity (the operating temperature at 210° F or 102° C).

If talking about the 0W20 vs 5W20 summer experience, the 5W20 does better than its opponent due to the slight thickness of oil (but there are better motor oils like 5W40 for hot temperature lubrication).

In the 0W20 vs 5W20 winter debate, the table turns as 0W20 is an ideal motor oil for this purpose. It flows better in freezing weather which causes the engine to stay hot. 

And this contains a multi-grade label to perform well from – 40° C to + 30° C (– 104° F to + 86° F) temperature.

On the other hand, the 5W20 motor oil has a – 35° C to + 30° C (– 95° F to + 86° F) temperature range for safe application.

Winner: 0W20 Oil.


The 0W20 stays on the top for its smooth and quiet performance while the 5W20 cleans the engine and reduces the chances of a cold start due to freezing temperature.

They two give diverse performance feel and I would prioritize the max benefits of them to give a winner at the end. Back to the topic, the 0W20 oil saves fuel from consumption so that you spend fewer bucks on it.

But it doesn’t improve engine MPG. In comparison, the 5W20 oil increase fuel economy and cut down CO2 emission. It raises the engine protection and supports fluidity to perform always great. That’s why most mechanics suggest using it.

Winner: 5W20 Oil.

Ingredient List

Both are made out of different remedies which makes one better for winter application. To begin with, the 0W20 multi-grade SAE oil is built out of 1-Decene (add moisture), Homopolymer (better resistance to high temperature), and Hydrogenated (modify viscosity) elements.

Thanks to these blends, it is able to lube the engine parts better. In contrast, the 5W20 motor oil is formulated out of synthetic base oil including refine, hydrocarbon atoms (add lubrication), and additives.

Winner: 0W20 Oil.

Suitable For

If I speak of their application style, both are made for different types of truck engines. Nearly all modern petrol and gasoline-style engine car uses the 0W20 oil.

Apart from these, it is ideal for 2-wheelers and aviation trucks to use in max cold temperature. This kind of oil suits the daily use trucks as it would work better for keeping the engine hot and operating.

Conversely, the 5W20 oil is great to use on passenger trucks, lightweight cars, 4-wheelers, and gasoline engines. But this type of oil is not suitable for daily usable truck engines.

Winner: 0W20 Oil.

Price Point

If mentioning the 0W20 vs 5W20 price, they noticeably differ if you analyze the recent stats. To make it clear, the 0W20 oil comes at $30 – $200 based on the quality.

Some oil comes at less than $30 like the Castrol 03124 Edge even being a top-notch item. On the contrary, the 5W20 oil started in the $20 – $170 price range.

Winner: 5W20 Oil.

Lasting Ability

As for lasting capability, the 0W20 oil will last not more than 5,000 – 10,000 miles. In other words, using this kind of oil will help your engine stay operating for 6 – 12 months.

Then again, the 5W20 oil will last for around 10,000 – 20,000 miles between the oil change. Meaning that it will keep the engine lubricated for 1 to 2 years.

Winner: 5W20 Oil.

Wrap Up

Finally, the 0w20 vs 5w20 debate is over after hinting at their differences. Depending on the engine and performance requirement, you can select one easily.

I would pick the 5W20 if price, longevity, fuel economy, and engine protection are what matters most when looking for motor oil.

But then again, I would go with 0W20 instead of 5W20 if my priorities are viscosity, lubrication, and better flowing at cold temperatures.  

Hope this guide was able to give plenty of information that you need to know for making a choice between both of these oils. See You Soon!
