0W20 vs 5W30 Fuel Economy (2023)? [Explained]

The viscosity, or thickness, of motor oil, can have an impact on fuel economy in a vehicle. Two common viscosities that are used in automobiles are 0W-20 and 5W-30.

The numbers in these viscosities refer to the oil’s weight, with the “W” indicating that the weight measurement was made at low temperatures. The first number, before the “W,” refers to the viscosity of the oil at low temperatures, while the second number refers to the viscosity at operating temperature.

0W-20 oil is a very thin oil that is used in some newer cars. This oil is designed to reduce friction between moving parts and improve fuel economy. On the other hand, 5W-30 oil is a slightly thicker oil that is recommended for a wider range of vehicles, especially those that are older or have higher mileage. This oil is designed to protect against wear and tear.

Always it is best to check the car manual for the recommended viscosity for that particular make and model. In this blog, we shall discuss 0W-20, 5W-30, and 0W-20 vs 5W-30 fuel economy, 0W-20 vs 5W-30 oil change intervals, and also in terms of engine protection.

What is 0W20?

0W-20 is a type of motor oil that is used in some newer vehicles. The “0W” part of the name refers to the oil’s viscosity at low temperatures, while the “20” refers to the oil’s viscosity at operating temperature. The “W” in the name stands for “Winter,” which indicates that the oil’s viscosity is measured at low temperatures.

0W-20 motor oil is a very thin oil, which is designed to reduce friction between moving parts in an engine. This reduction in friction can improve fuel economy, as well as lower emissions.

However, this thin viscosity also means that 0W-20 oil may not provide as much protection for an engine’s moving parts as thicker oils, such as 5W-30.

0W-20 oil has become increasingly popular in recent years, as car manufacturers look for ways to improve fuel efficiency and reduce emissions. In order to meet increasingly strict emissions and fuel efficiency regulations, car manufacturers have been developing engines that are more efficient and produce fewer emissions. One way they have been able to achieve this is by using thinner oils, such as 0W-20, which reduces friction and improves fuel economy.

It is important to note that not all vehicles can use 0W-20 oil and it is crucial to check the vehicle’s manual for the recommended viscosity for that make and model. Also, it’s not recommended to use 0W-20 oil in vehicles that are older or have higher mileage, as it may not provide enough protection for the engine’s moving parts.

Additionally, it is highly recommended to use only the recommended oil grade from the manufacturer, and ensure that the oil is licensed by reputable organizations such as API (American Petroleum Institute) or ACEA (Association des Constructeurs Européens d’Automobiles)

What is 5W30?

5W-30 is a type of motor oil that is commonly used in a wide range of vehicles, particularly those that are older or have higher mileage. The “5W” part of the name refers to the oil’s viscosity at low temperatures, while the “30” refers to the oil’s viscosity at operating temperature. The “W” in the name stands for “Winter,” which indicates that the oil’s viscosity is measured at low temperatures.

5W-30 oil is slightly thicker than 0W-20 oil and it’s designed to protect the engine’s moving parts from wear and tear. It is formulated to provide better protection against wear and tear under high loads, extreme temperatures, and other demanding conditions.

It’s also a good choice for cold weather and provides better low-temperature performance than a heavier oil like 10W-40, which will thicken and flow less easily in cold temperatures, making it harder for the engine to turn over.

5W-30 oil is also versatile, it can be used in a wide range of vehicles, including those with gasoline and diesel engines, as well as in both older and newer vehicles. It is recommended for use in cars, trucks, SUVs, and in some light-duty diesel engines.

It is also approved by many car manufacturers, and it’s also recommended by industry organizations such as the American Petroleum Institute (API) and the International Lubricant Standardization and Approval Committee (ILSAC).

Furthermore, synthetic 5W-30 oils are also available, they are made with a blend of synthetic base stocks and conventional oil and they have a higher level of performance and protection than conventional oils. It can provide better fuel economy and lower emissions than conventional oil, and it also provides better protection against wear and tear, as well as better cold-weather performance than synthetic oils.

0W20 vs 5W30 Fuel Economy?

When it comes to 0W20 vs 5W30 fuel economy, the most important factor to consider is the viscosity of the motor oil. Viscosity is the measure of the oil’s thickness or resistance to flow, and it plays a significant role in the fuel economy of a vehicle. The two common viscosities that are used in automobiles are 0W-20 and 5W-30.

0W-20 oil is a very thin oil that is designed to reduce friction between moving parts in an engine. This reduction in friction can improve fuel economy and lower emissions, making it a popular choice for newer vehicles that are designed to meet increasingly strict emissions and fuel efficiency regulations.

However, it is important to note that not all vehicles can use 0W-20 oil, and it may not provide as much protection for an engine’s moving parts as thicker oils.

On the other hand, 5W-30 oil is a slightly thicker oil that is recommended for a wider range of vehicles, especially those that are older or have higher mileage. This oil is designed to protect against wear and tear, and it’s a more versatile oil that can be used in a wide range of vehicles. However, it may not provide as much improvement in fuel economy as a 0W-20 oil.

Using 0W-20 oil in a vehicle that is designed to use it can lead to slightly better fuel economy than using 5W-30 oil. This is due to the fact that the 0W-20 oil is thinner, which reduces the amount of energy required to pump it through the engine and provides less resistance to the engine’s moving parts, which in turn results in lower engine friction and better fuel efficiency.

However, it is important to note that using the correct oil for your vehicle is crucial for the protection of the engine’s moving parts. Always it is best to check the car manual for the recommended viscosity for that particular make and model.

0W20 vs 5W30 Oil Change Interval?

The interval for an oil change can vary depending on a number of factors, including the type of oil used. 0W-20 and 5W-30 are both types of motor oil that have different viscosities, or thicknesses, at different temperatures.

0W-20 oil is a fully synthetic oil that is designed to flow easily at low temperatures. It is often used in newer vehicles that have smaller, more tightly toleranced engines, such as those found in hybrids and electric cars. This oil is also recommended for use in colder climates, where low-temperature starts are common. Because of its thin consistency, it can provide better fuel economy and reduce emissions.

5W-30 oil, on the other hand, is a more traditional motor oil that is thicker at low temperatures and thinner at high temperatures. It is a multi-grade oil that is suitable for use in a wide range of temperatures and is recommended for use in cars that operate in a variety of temperatures and climates. This oil is commonly used in conventional gasoline and diesel vehicles.

The recommended interval for an oil change can vary depending on the vehicle’s make and model, as well as the type of oil used. In general, however, if you are using 0W-20 oil, you may be able to go longer between oil changes than if you were using 5W-30 oil. The recommended interval for an oil change is usually listed in the owner’s manual, so it’s a good idea to consult this document for specific guidance.

Some other factors that may impact your oil change interval include:

  • Driving conditions such as frequent stop-and-go traffic or heavy loads
  • How well do you maintain your car
  • And the quality of oil you use and brand

It’s also important to keep in mind that the interval for an oil change can change depending on the condition of your vehicle, so it’s important to check the oil level regularly, and have your vehicle checked by a mechanic if you notice any signs of wear or trouble.
