0w20 vs 5w20

If you buy something through a link in our posts, we may get a small share of the sale.

Motor oil, engine lubricant, or engine oil; nothing but simple mixtures of additives to base oil. It is important for lubricating engine parts, reducing friction, and protecting the engine of any vehicle. Hence, choosing the right motor oil for your vehicles amongst 0w20 vs. 5w20 is necessary.

0w20 Motor Oil

0w20 oil is purely synthetic. This oil price is pretty high per quart, but the quality is what speaks for its worth. Synthetic oil such as 0w20 is more common for its ability to sustain diverse driving conditions.

It doesn’t let the vehicle break down anytime sooner, in comparison with the conventional motor oil. One of the biggest global automobile companies, Toyota, recommends using 0w20 motor oil for all of its vehicles.

For making 0w20, high-quality base oil and strong additives are essential. In addition, the base oil chosen for making 0w20 motor oil should flow and protect the engine at low temperatures. Therefore, synthetic base oil is helpful for this purpose.

The additives used for the purpose must be quite thin to let the oil move well. But they should still be adequate to protect the modern-day advanced engines. With the rising technical advantages of automobile engines, the demand for 0w20 is increasing.

5w20 Motor Oil

5w20 is one of the common motor oils that is suitable for colder climates. It lubricates the engine well at freezing or low temperatures. Following that, it experiences less friction. Starting a car engine in a cold climate requires thin oil to lubricate the parts properly. Therefore, here it can be quite beneficial.

5w20 is a less viscosity oil that is probably linked to optimal performance and enhances fuel efficiency when used in cold climates.

However, 5w20 is not preferable for significantly hotter climates, as it will lose its viscosity and cannot offer optimum protection to the engine parts. The viscosity of 5w20 at 100 degrees Celsius and 40 degrees Celsius are 8.9 and 49.8, respectively. Hence, it shows the effect of heat over the viscosity of 5w20.

0w20 vs 5w20

0w20 motor oil replicates that the viscosity is zero when in cold temperatures. However, the viscosity rises to 20 at the operating temperature. The viscosity of 5w20 at operating temperatures is 20 but is five at cold temperatures.

Both oils are usable in regions with cold weather but are ideally fit for use in moderate hot climates. 0w20 and 5w20 are two modern synthetic motor oils that do more than just lubrication and are used in vehicles running in cold conditions. However, they have subtle differences that impact the performance of vehicles.

So, let’s enlighten ourselves with the possible similarities, differences, and major distinguishing factors of 0w20 and 5w20. It will help you in deciding better which one to pick.

Similarities Between 0w20 and 5w20 Motor Oils

  • The viscosity for 0w20 and 5w20 at operating temperatures is the same as 20.
  • Both of these oils are ideal for running thin at moderately cold temperatures.
  • Both of these oils ensure that your fuel consumption by vehicle remains low.

Differences Between 0w20 and 5w20 Motor Oils

  • For icy weather conditions, 0w20 is better than 5w20.
  • The range of 0w20 is -40o to 20o, whereas that of 5w20 is -25o to 20o.
  • The cold temperature viscosity is different for 0w20 and 5w20. They are 0 and 5, respectively.
  • 0w20 is comparatively expensive than that of 5w20 because of the top-notch effectiveness in extremely cold conditions.
  • 5w20 consists of both conventional and synthetic oil, whereas 0w20 consists of only synthetic oil.

Major Distinguishing Factors

  1. The flashpoint for 0w20 is 224 degrees Celsius, whereas for 5w20 is 230 degrees Celsius.
  2. In addition to that, 5w20 is favorable for Vans and SUVs, whereas 0w20 is preferable in hybrid engines and gasoline engines.
  3. 5w20 is preferable for everyday engines. However, 0w20 is preferable for both casual and rough driving purposes.

When To Use 0w20

You can use 0w20 under conditions like:

  • When you need superior engine protection to deal with the stress factors such as wear, deposits, and heat
  • If you are running the vehicle in extremely cold temperature or an average hot climate
  • When you seek to suppress the fuel consumption rates and enhance the engine efficiency

When To Use 5w20

You can use 5w20 under conditions such as:

  • If you want to run your vehicle in moderate winter and summer climate
  • It is recommended for vehicles embedded with modern engine tech for enhanced performance.
  • We suggest not to use 5w20 in older engines without referring to the owner’s manual.

Which Is Better: Final Verdict

The quality of both motor oils is better, with base oils making up to 70 to 90% of the total engine oil, whereas additives are of mere 10 to 30%. The letter & number arrangement for these motor oils is as per the SAE grades. These grades are to represent the thickness of oils.

Motor oil protects the engine from wear & tear, maintains the viscosity, prevents acid build-up, and keeps the turbo safe. So, it is a must. However, as per all the information stated for 0w20 vs. 5w20, there is a clear picture that these two motor oils have only a few differences between them.

Both of them are quite suitable for use in various engines for all driving conditions. However, the subtle differences are crucial for the maintenance and life of a vehicle engine. Therefore, even though the distinguishing factors are next to negligible, you still need to consider them before choosing the oil.
