Comparison Between 0w30 Vs 5w30: Which Is Better Motor Oil?

Engine Produces huge wear & friction during its operation. You can easily reduce this friction and wear by using high-quality engine oil. On the other hand, if you use low-quality motor oil it can damage your engine equipment.

As a result, if you want to keep your engine healthy, it’s important to use the right engine oil in your vehicle. To keep your engine running smoothly and healthy you can use 0w30 and 5w30.

But which one is best for your engine if you haven’t any idea? For you, we have furnished the comparison between 0w30 vs 5w30. So, don’t go anywhere, please.

0w30 Vs 5w30

About Of 0w30:

0w30 oil is the genuine and common type of engine oil. This oil is also known as “standard” or “universal” engine oil.

0w30 oil is a synthetic mixture of alpha-olefin and polyalphaolefin (PAO). Also, it comes to provide performance similar to traditional oil but with thermal protection and reduced volatility.

Though this is a synthetic lubricant you can use this oil in many applications. Since it’s one of the synthetic motor oils in the market it also works well as a gear and an anti-wear oil.

Besides this, it’s composed of 30% base oil and 70% synthetics, making it an excellent choice for any vehicle. That means it won’t break easily or require frequent replacement.

Example of the 0w 30 engine oil from Mobil 1


  • Excellent protection against heat damage
  • High-performance additive package
  • Thinner than 5w30 motor oil when cold
  • Fast flow rate
  • Good wear protection in cold weather


  • The tendency to break down at higher temperatures may be a little higher

About Of 5w30:

5w30 oil contains five winter viscosity grades and contains no detergents or anti-wear additives. This oil is made with synthetic base oil so it can offer better lubrication at higher temperatures.

As a result, your engine parts will have less wear and tear and can save you money over time. However, 5w30 oil is perfect for vans, light trucks, passenger cars, and SUVs. Besides you can use it in turbo engine cars which need high performance.

Example of 5w30 full synthetic motor oil from Valvoline


  • Same viscosity as 0w30 oil at operating temperature
  • Good protection against heat damage
  • Provides an amazing additive package
  • 5w30 may offer slightly longer longevity than oil


  • Not good for cold weather

0w30 and 5w30 Fuel Economy

The type of motor oil you use for your vehicle has a huge impact on the fuel economy you get. Generally, the lower the oil viscosity, the better fuel economy you can expect.

It’s because the thinner the oil inside the engine, the less drag and resistance it has. And the less resistance engine parts encounter, the easier it is to move through the oil.

Since both 0w30 and 5w30 oil contains the same viscosity at operating temperature, one wins on this round. In cold weather 0w30 oil’s lower viscosity allows better fuel economy during your car’s cold start.

But the reality is that it only makes up for an infinitesimal percentage of an engine oils overall fuel economy. Not to mention, many other reasons that affect fuel economy. So 0w30 may offer some better fuel economy than 5w30 oil under ideal conditions, but it won’t be that big of a difference.

BMW 5w30 vs 0w30 :

All BMW manufacturers recommend 5w30 motor oil. 0w30 motor oil is not on their recommended list. But 0w30 motor oil is best suited for use in cold climates during winter. Additionally, to know which oil is best for your BMW, you should check your owner’s manual.

Can I Use 5w30 Instead of 0w30?

It will depend on various things. Factors determining which motor oil to use will depend on two factors. The first reason to consider is temperature.

And the second factor is viscosity. So, again, the manufacturer will recommend this motor oil for your automobile. But it will depend on two factors. The car you drive can also be a factor. Every car has recommendations for which motor oil to use.

These companies will specify their recommended engine oil in their owner’s manual for every vehicle. Consult your owner’s manual to find out which of these two motor oils is perfect and recommended for you.

Which Is Better, 5w30 or 0w30 Oil?

Accordingly, 0w30 and 5w30 motor oil are only slightly different. They differ in their viscosity. For example, 0w30 is thin at very cold temperatures. Nevertheless, they contain the same viscosity at average operating temperatures.

Both oils’ only difference is that 0w30 oil is always synthetic. In contrast, 5w30 oil is traditional or synthetic. Conventional motor oil won’t meet 0w30 motor oil specifications.

0w30 motor oil is a specific type of oil, and it has a lower viscosity you can use in place of 5w30 oil. 0w30 motor oil is a type of fully synthetic motor oil. Ergo, it’s also able to improve and provide fuel economy due to its low friction properties.

Nonetheless, if you compare it with 0w30 motor oil, 5w30 motor oil has a higher viscosity level. Hence, you can use it different temperatures, and in different types of cars.

0w30 Vs 5w40:

0w30 motor oil is used in weather conditions from frost to minus thirty-five degrees and up to twenty-five degrees. It is a universal lubricant for modern motors. 0w30 motor oil is a low-viscosity oil, and it can also be a replacement for 5w30 or 10w30 motor oil.

Particularly, it’s also able to enhance and improve fuel economy due to its low friction properties. On the contrary, 5w40 oil contains high viscosity and is suitable for all temperatures. In general, to know which oil can be best for your engine, you should check your owner’s manual.

0w30 Vs 0w20:

0w30 and 0w20 both oils are thicker and lower coagulate at 0 degrees F, a shallow temperature. This way, the internal parts of the engine will not stick together and will be easier to remove.

Ending with a ‘W’ we move to the following number. One oil has 20 and the other has 30. As the graph shows, this means that at higher temperatures, 0W-20 will thin out faster than 0W-30. Because of this, the oil will be less valid and reliable at higher temperatures.

There isn’t much difference between these two oils until you get well below freezing. One viscosity specification you may not have considered is HTHS. You can ignore the KV40 and KV100 specifications.

0W-30 has the benefit of a slightly lower HTHSV of 3.0cP vs 3.1cP for 5W-30. This compensates for the slightly lower VI 0W-30 that would otherwise result in heavier oil at normal hot temperatures. Mobil 0w30 oil is best for cold temperatures.

Mobil 0W30 is relatively new but it meets GM spec 4718M as marked on the back of the bottle. It meets the specs for the Tundra 4.7L motor.

Amsoil 0w30 and 5w30:

Broth oil can perform similarly, the 0W-30 has a slight edge during cold weather and the 5W-30 does slightly better at higher temperatures. Your vehicle and wallet never know the difference between them.

In particular, if you want you can get an extra 30% per quart for 0w30. And you can do it after buying extra 0w30 oil. We want to say that 0w30 is the best oil on the market that you need to buy for your car.

FAQ (Frequently Asked Questions):

Q. Should I Use 0w30 0r 5w30?

Yes, you can use 0w30 or 5w30. You can use 0w30 motor oil in cold weather and 5w30 is suitable to use in warm weather. You can use both of this oil in light-duty diesel and gasoline engines.

Q. What temperature is 0W30 good for?

0W30 motor oil is suitable for seasonal climates and variable temperature settings, and the temperature range is -40°F to 86°F. However, it’s not ideal for heavy-duty use at high temperatures.

Q. Will using 5w30 instead of 0w30 in my BMW damage my car?

No, it’s not damaging your BMW car. 0w30 will perform better at lower temperatures. To know about it we would double-check the 30w oil. Most 30w oils are too thick to flow into that small tolerance. Most German engines now use 0w20. Double-check to make sure 30w is the correct oil.

Final Word:

0w30 vs 5w30 motor oil: both oils are good choices, but both of them have their advantages and disadvantages. 0w30 oil is suitable to use in cold weather because it flows more easily. Likewise, it is more prone to gum up than other types of oil.

Alternatively, 5w30 motor oil is good for high temperatures because it is thicker and contains higher grades. Thus, this oil isn’t best for all engines. Ultimately, the best choice will depend on your personal needs and the climate.
