Difference between 5W20 and 5W30

Synthetic oils were developed to lubricate and protect your engine while providing improved performance. But how do you decide which oil is right for your vehicle? One way to determine the best fit is by understanding the differences between 5W20 and 5W30 motor oils. In this blog post, we’ll explore why it’s important to choose the correct oil viscosity as well as discuss variations in cost and performance characteristics of these two highly popular types of synthetic motor oils. You don’t have to be an automotive expert to understand this helpful guide – so let’s get started!

What is 5W20?

  • 5W20 is a kind of motor oil that is increasingly popular among car owners. 5W20 is a type of synthetic blend motor oil that offers superior performance compared to traditional 5W30 and 10W30 viscosities.
  • 5W20 engine oil works well for both hot and cold temperatures, with its improved cold start as well as superior high operating temperature performance. Not only does 5W20 reduce frictional loss from the engine components, but it also provides superior fuel economy over conventional 5W30 or 10W30 oils.
  • 5W20 has become more readily available in recent years and can be found in many automobile parts stores. For those looking for an engine lubricant to perform better than regular 5W30 or 10W30 oils, 5w20 represents a great option.

What is 5W30?

5W30 is a type of motor oil designed to improve vehicle performance and fuel efficiency while reducing emissions. This oil contains a combination of 5-weight and 30-weight base stocks, which are blended to form an optimized viscosity level that works well in both warm and cold weather conditions.

  • 5 weight refers to how easily the oil flows at low temperatures, whilst 30 weight denotes its resistance to thinning under higher temperatures intensified by the engine’s kinetic energy.
  • 5W30 oil offers numerous benefits for cars, including increased lubrication for moving parts, protection from dirt buildup and corrosion of metal surfaces, improved fuel economy, and reduced friction between parts.
  • Furthermore, 5W30 motor oils now even come in synthetics that can provide better protection and reduce wear over time. No matter what kind of car you own or where you live, 5w30 is designed to help keep your vehicle running at its peak performance!

Difference between 5W20 and 5W30

5W20 and 5W30 are two types of motor oil, both commonly used in gasoline engines. 5W20 has a thinner viscosity at cold temperatures than 5W30, meaning 5W20 is more suitable for areas with colder climates since it can better flow in cold weather. 5W30 is thicker than 5W20, which means it can provide superior protection against heat breakdown and wear in hotter conditions. 5W30 is also better suited for older vehicles as it lubricates parts better than 5W20 to prevent friction caused by worn-out components. Ultimately, the type of oil you select should depend on where you live, the age of your vehicle, and how hard you drive it.


In short, the main difference between 5W20 and 5W30 is that 5W20 is a thinner oil while 5W30 is a thicker oil. This means that 5W20 is better for cooler temperatures while 5W30 performs better in warmer conditions. However, both oils have their pros and cons, so it’s important to consult your car’s owner manual or a professional mechanic to determine which type of oil is best for your vehicle.
