Difference between 0w20 and 5w30 motor oil (2023)

Motor oil is defined as a substance added with the various amount of additives with are used as lubrication for internal combustion engines. The sole purpose of motor oil is to reduce wear and tear, and friction from the every moving part of an engine. One of the important ingredients in motor oil is detergents because it improves the piston sealing and helps to cool the engine by diverting heat from the moving parts. Changing your car’s oil and the oil for your machinery at regular intervals is a very important practice you ought to know because failure in changing the oil will result to the accumulation of dirt in the engine leading to serious engine damage later in the future. Motor oil is mostly used to power all forms of machinery which includes lawn mowers, cars, generators, motorcycles, and many other machines. It functions in various capacities in the engine such as reducing wear in engines, lubricating the moving areas, making the engine parts cool, etc. It is highly essential to the lifespan of every engine. Every time your engine is in motion, residue from the combustion engines tend to adulterate your engine, and when there is an accumulation of this residue, they can create dirt and filthy deposits in the engine. Also, the failure to look after your engine by changing the oil can lead to negative issues with your engine, and when the components of the engine are dirty, the efficiency, longevity, and speed of your vehicle can degrade.

Difference between 0w20 and 5w30 motor oil (1)

Motor oil consists of various types, brands, price, etc. But the most important ones we are going to take note of is the 0W-20 and the 5W-30 motor oil. What makes these oils unique? What brands will people go for? Where can they be used?

In this article, we will highlight the differences between these two popular oils. Let’s dive in.

0W-20 OIL

These oils are mostly known as low viscosity oil, and this particular oil type is becoming very common amongst popular buyers in the market because it is said to deliver the best performance. It readily means that the 0 oil will flow well and better at a cold temperature more than 5W-30 oils even while maintaining the same viscosity. The 0W-20 is said to be the best oil in the market because it helps to reduce environment hassle on waste oil disposal.

The 0 before the W on the label is referred to as the viscosity of the oil when the engine is cold.

The W refers to winter.

The 20 at the end represents the viscosity of the oil at a higher temperature according to the Society of Automotive Engineers. The lower the number, the thinner the viscosity of the oil

THE 0W-20 oil is also commonly referred to as the multi-viscosity oil because it contains a certain amount of special additives to make it have different viscosities when cold. Temperatures and certain climate conditions affect the use of 0W-20 over the 5W-30 engine oil. During summer, viscosity becomes higher, and during winter, viscosity becomes lower so that why it’s preferred to put the OW-20 in summer seasons. Putting the 5W-30 in summer seasons will cause the oil to be thinner leading to damage in the long run.

Benefits of using 0W-20 engine oil.

Every day, thousands of cars in factories are replaced with 0W-20 synthetic engine oil for improved overall engine performance and improved environmental conditions in a world where the rate of pollution always seems to be escalating. There are very minimal losses in the oil especially when it is cold due to its low viscosity of the oil.

Most times, 0W-20 synthetic oil can be more expensive than the 5W-30, spending that extra cash for the lifespan of your vehicle can turn out to be a very worth-while investment. In the upcoming years, we’re more likely to see most cars top up their engine oil with 0W-20 synthetic engine oil as manufacturers are trying their very possible best to minimize fuel consumption rates and improve total engine efficiency.


The 5W-30 motor oil is another very good and highly efficient motor oil. It is an overall preparation that can function in environments where there are extreme colds and extreme heat. The 5W-30 engine oil assures every machine user of good start-up and good low-temperature protection. In a 5W-30 for example, 5 represents the viscosity of the oil at a low temperature of 5 degrees Celsius. The more the number decreases, the better the cold start temperature and the thinner the motor oil will be. W represents winter, and the number 30 describes how thick the oil will be at the operating temperature of the engine. Motors oils like this 5W-30 are also very widely used and most times general accepted by machine users especially car users instead of the 0W-20 is that they can function very well in all but highly extreme cold and hot temperatures. 5W-30 motor oil is generally considered as multi-grade motor oils meaning that the motor oil can be categorized into two viscosity grades.

Some people prefer the 5W-30 motor oil to 0W-20 motor oil because of certain places with warm winters and the ready availability of the motor oil. 5W-30 motors oil are easier to find than the 0W-20 motor oil in regular lubrication stores. Although it occasionally seems like the OW-20 motor oils are on the top of the chain when it comes to efficient motor oil because most vehicles, those already in use and those that are still with the manufacturers tend to always recommend 0w-20 motor oil for their machinery. Nevertheless, the popularity of the 5W-30 motor oil is slowly gaining momentum because it tends to adapt properly to a range of weather conditions, especially during the warm winter seasons.

BENEFITS OF 5W-30 Engine oil.

The 5W-30 oil is a very good multi-grade oil for low starting temperatures as well as high summer temperatures. More so, it is highly fuel-efficient creating less drag on the moving engine parts.

The 5W-30 oil is fabricated to be used for machinery situated at locations where the temperature is lower than -22 degrees F.

Some Automobile engineers across the world often recommend engineers to increase their fuel economy ratings. Motor oil, such as 5w-30 gives little or no friction in the engine, which in turn helps to increase the fuel economy. Most times, Auto manufacturer recommend 5W-30 oil which is a thinner motor oil. But in some cases, the increase in the fuel economy later results in an increase in the wear and tear of the engine.


Your machine’s engine oil especially the one for your car is very important and highly essential that you changed the oil on a regular basis. For a car, every 10000 miles should require an oil change. Motor engines are the backbone and blood of your machinery that why at regular intervals, you check out the particular oil that is right for your vehicle. Currently, Most of the motor oil produced by manufacturers are called multi-grade oil, which, depending on the temperatures is designed to have different behaviors. Society of Automotive Engineers (SAE) is the umbrella body in charge of testing these motor oils, giving them their particular code and making them fit for public use.


Don’t select any type of grade of oil. There are many components of consider such as vehicle’s age, miles, current engine condition, and climate. Use these articles for a detailed comparisons of viscosity, cost, and climate to select the correct one.
