Similarities Between 0W40 Vs 5W30 Engine Oil

Oil Type

The 0w40 and 5W30 don’t have a lot of similarities between them. The base material of these two engine oils is synthetic oil, which is a major similarity between these two oils.

Additives

When it comes to other additives, the 0w40 and 5w30 engine oil come with anti-wear, anti-foam, and anti-rust agents.

Difference Between 0W40 Vs 5W30 Engine Oil

Viscosity Grade

The greatest difference between the 0W40 and 5W30 engine oil is their viscosity grades. Both oils have different low and high-viscosity grades. The 0w40 engine oil comes with a lower viscosity grade of 0 and a higher viscosity grade of 40.

In contrast, 5W30 engine oil comes with a lower viscosity grade of 5 and a higher viscosity grade of 30.

Fuel Economy

Another major difference between the 0W40 and 5W30 engine oil is the fuel economy. The 0W40 engine oil offers better fuel economy due to the fact that it is thinner, which allows it to reduce friction as much as possible and improves the engine performs better in different driving situations, which then gets you better fuel economy than the 5w30 engine oil.

Engine Wear

When it comes to engine wear, the 0W40 engine oil has slightly more engine wear than the 5w30 engine oil. This is because the 0w40 engine oil is thinner, which increases engine wear between the engine components.

Suitable Weather Conditions

Considering the weather conditions is very important when choosing between the 0W40 and 5W30 engine oil.

The 0W40 has a slight advantage over the 5W30 engine oil because it can withstand hot as well as cold temperatures. Conversely, 5W30 engine oil is only suitable for cold weather conditions.

Temperature Range

When it comes to the temperature range, the 0W40 can withstand from -40 to 40-degree celsius temperature. A 5W30 engine oil, on the other hand, can handle temperatures as low as -35 degrees Celsius.

Life Expectancy

The 0W40 engine oil has a life expectancy of about 10,000 miles, whereas the 5W30 engine oil has a life expectancy of 5,000 miles. The 0W40 engine oil goes through a lot of tests in comparison to the 5W30 engine oil, which makes it more durable and last longer.

Engine Compatibility

The 0W40 engine oil is compatible with turbocharged petrol and diesel engines. On the flip side, the 5W30 engine oil is compatible with hydraulic tappets, petrol, diesel, and CNG engines.

Friction

The 0w40 engine oil creates the least amount of friction as it is thinner than the 5W30 engine oil. In comparison, the 5W30 engine oil creates slightly more friction than the 0w40 engine oil.

Thermal and Oxidation Stability

When it comes to thermal and oxidation stability, then again, the 0W40 engine oil has an advantage over the 5W30 engine oil as it performs better with excellent thermal and oxidation stability.

Pros and Cons of 0W40 Vs 5W30 Engine Oil

0W40 Engine Oil:

Pros	Cons
Better fuel economy	More engine wear
Suitable for hot and cold weather
Excellent temperature range
Least friction

5W30 Engine Oil:

Pros	Cons
Suitable for cold weather	Average fuel economy
Compatible with hydraulic tappets engines	Poor oil flow
Less engine wear

Which is Better Engine Oil: 0W40 Vs 5W30?

The 0w40 engine oil is better in comparison to 5w30 as it offers the least friction and an excellent temperature range. On top of that, it has a great life expectancy. Also, it is ideal to be used in cold and hot weather.
