0W-20 vs 5W-20: What Is The Difference
If the engine is the heart of your vehicle, then engine oil is its blood. It’s extremely important to find the oil that provides proper lubrication, cleaning and protection in specific weather conditions. Given all the options out there, it is not so easy to pick the right one for your vehicle. There are quite a few things the vehicle owners have to know about synthetic oil to make a choice. So today we’ll talk about synthetic motor oil properties, compare two similar yet quite unique types of multi-grade oils (0W20 and 5W20) and try to give the answers to all your questions on this topic in our FAQ section. If you consistently use the wrong type of oil for your engine you might end up damaging your motor or even worse, incur engine failure. New engines are typically pretty expensive so it is best to use the right oil in the first place. However, if you have to replace your engine, look at a cheap rebuilt engine from an online retailer like carpartplanet.com.
5W20 vs 0W20 - Similar Or Different?
Many vehicle owners wonder if there is any difference between 0W20 and 5W20 synthetic motor oil. We’ll find it out soon, but first let’s take a look at short descriptions of these oil types.
Brief review on 0W-20 motor oil
0W-20 is fully synthetic motor oil with thinner viscosity. It protects the motor components perfectly. 0W-20’s temperature range is from -40° to 20°, so it’s great for cold winters, but can be used in mild springs and summers. One of 0W-20 advantages is better fuel economy – it can give your vehicle extra mileage. 0W-20 meets the API SN requirements and is approved by many vehicle manufacturers as a recommended oil.
Brief review on 5W20 motor oil
5W20 is fully synthetic multi-grade oil with thicker viscosity that provides better sealing action. Adjustable for both mild summers and not too cold winters, as it’s temperature range is from -25° to 20°. It protects the engine greatly and works decently for regular everyday use. Can also optimize the fuel economy. This oil also meets all the API SN requirements and is recommended for use by many modern car brands.
0W20 and 5W20 – so similar but still different
The main difference between these two synthetic oil types hides into their codes. So what do the numbers and letters of the code mean?
The letters and numbers in the code indicate the main properties of the synthetic oil. Let’s take 5W20 as the example:
- 5 – the number at the beginning refers to the weight of the oil.
- W (winter) – this letter means that this oil variety is suitable for use in colder climates.
- 20 – the number in the end indicates viscosity (thickness) of the oil.
Synthetic motor oils get thinner when it heats up and thicker when it’s cold outside. 5 – the first number – shows the viscosity of synthetic oil in cold temperatures. 20 – the last number – indicates oil’s viscosity at operating temperatures.
0W20 vs 5W20 Viscosity explained
The less viscous synthetic oil is at low temperatures, the lower number you’ll see at the beginning. 0 in 0W20 means that the viscosity equals 0 in cold temperature, so, as you might have guessed, 0W20 will flow better at lower temperatures than 5W20.
0W20 – 5W20 Thickness differences
It is important to take into account the thickness of the motor oil. The higher the viscosity, the better the load it can support. 0W-20 is too thin for trucks, SUVs, etc., it is intended for lighter use in diesel and petrol engines. 5W20, in contrast, can support heavier loads, so it’s perfect for vans, 4×4 off-roaders, etc.
Although both oils are intended for use in cold-weather regions, 0W-20 is a better option for those who live in colder regions, where the temperature falls beyond -25°. In extremely cold temperatures 0W-20 also gives slightly less wear at cold startup, as it flows freely at -30°/-40°. 5W-20, in its turn, resists shear under heavy loads better than 0W-20 thanks to its higher viscosity. So in the battle of 2 synthetic motor oils with very similar properties 0W-20 receives “Better low temperatures performance” award and 5W-20 wins “Better heavy-duty performance” trophy.

Faq - Everything You Need To Know About Synthetic Motor Oils
What is synthetic motor oil? What advantages does it have?
Synthetic oil is an engine lubricant made from base – usually highly refined crude – oil, carrier oil and powder additives. It is artificially made – synthesized, therefore it is called synthetic. Also known as multi grade oil, as it meets the requirements of multiple (two) viscosity grades and can be used in low and high temperatures. Motor oils help to minimize friction between different parts of the engine; thanks to its properties synthetic oil provides better lubrication by forming continuous layer over the motor parts, ensures smooth operation and increases engine life.
Synthetic motor oil advantages:
- Enhanced engine protection from wear and tear;
- Greater temperature resistance, better engine work under high and low temperatures;
- Cleaner motor – synthetic oil contains special additives that help to clean deposits and sludge;
- Lower oil consumption, longer intervals between oil changes;
- Fewer emissions.
Together all these advantages contribute significantly to increased engine performance and noticeable fuel economy.
Is synthetic oil worth paying more for?
Although full synthetic motor oils are more expensive than conventional or synthetic blends, all the expenses will be more than compensated, as synthetic oil provides increased fuel economy, and decreases engine wear and significantly extends engine life.
How often should I change synthetic oil?
I have an older car, can I use synthetic oil?
Absolutely yes, you can use synthetic oils both for older and newer vehicles.
Important: older cars often have considerably more mileage that results in engine wear and tear. In such cases use special high-mileage synthetic oils – they are thicker and provide better sealing; many high-mileage oils also contain higher doses of anti-wear additives.
Is synthetic oil compatible with gasoline engines? What about diesel?
Most synthetic motor oils are suitable for both diesel and gasoline engines. But still we recommend to check the label before you buy synthetic oil.
What is viscosity?
Viscosity is an important property of the motor oil. It is defined by the size of oil molecular structures. Viscosity indicates the oil’s resistance to flow, i.e. it shows how easily and fast the motor oil flows through the different parts of the engine. Synthetic oils with low viscosity pour easier at cold temperatures compared to the oils with higher viscosity.
Thinner or thicker oil – what is better?
It depends on the climate conditions where you live and the vehicle you drive. Thinner oils are good for using in colder weather and for light duty vehicles. Thicker oils are perfect for higher temperatures and heavier loads; they help to maintain oil pressure and film strength when it heats up.
What do Dexos 1 and Dexos 2 mean?
Dexos 1 motor oil is suitable for gasoline engine; Dexos 2 oil is designed for diesel engine but also can be used for gasoline engines too. These oils have different SAPS levels. Dexos 1 can handle oil changing interval for longer time thanks to its high SAPS level. Dexos 2, with its low SAPS level, can not hold oil changes intervals for a long periods, but it is more environmental friendly than Dexos 1.
Are 0W20 and 5W20 interchangeable?
More or less, yes. 0W20 and 5W20 are quite similar, but still you have to make a choice based on your local weather. If you’re not sure what oil to choose, then check what your owner’s manual says about suitable viscosity. You will possibly find both 0W20 and 5W20 in the list; if no – just use the oil recommended by your vehicle manufacturer.
My owner’s manual says I have to use 5W20, can I use lighter (5W10) or heavier (5W30, 5W40) grade?
No, it’s better to stick to the recommended grade and avoid using thinner or thicker oils. Using lighter motor oil will lead to faster mechanical wear and shorten engine life in the long-term perspective. Using heavier oil will also reduce engine life and decrease the fuel economy significantly. Never select the oil randomly.
Should I switch oils in winter and summer? Can I use 0W20 and/or 5W20 in warmer seasons?
Again, it depends on your local weather. 0W and 5W oils are typically recommended for winter use, but they’re also good for mild summers (up to +20°). If the temperature during the hot season reaches +20° or more, use thicker motor oil
Synthetic motor oils are more expensive than conventional, but they last longer and, what’s more important, offer enhanced engine protection, especially under heavy workloads and extreme weather conditions. There are so many choices when it comes to synthetic motor oils and it’s not so easy to fight the right one for your engine, especially when your vehicle manufacturer includes several recommended oil types in the owner’s manual. But there are two simple rules which can help to decide between many available options.
- Lower viscosity – for lower temperatures.
- Higher viscosity – for higher temperatures.
- Thinner oils – for lighter vehicles.
- Thicker oils – for heavy-duty vehicles.
And one more hint: check user reviews and buy synthetic motor oils from tried and trusted brands only. That is how you find the right lubricant for the best engine performance. No need to waste your money and experiment with different manufacturers or waste your time and go through multiple articles and reviews – we’re happy to take this challenge up for you.
