Difference Between 5w30 and 10w30

If you are a car owner, then it’s likely that at some point you’ve found yourself asking the question: what is the difference between 5w30 and 10w30 motor oil? It can be easy to feel lost when facing this decision in an auto parts store, but understanding the differences between these two different types of motor oils can help make your choice easier. In this blog post, we’ll walk through all you need to know about motor oil grades with special focus on comparing 5w30 vs. 10w30 — discussing their purposes and deciding which one is best suited for your vehicle type and preferences. So whether you’re looking for better protection against engine wear and tear or just seeking advice on selecting the right oil grade for your needs, read on!

What is 5w30?

5w30 is a type of motor oil that is used in many cars and trucks. It is designed to provide better protection for engines at start-up, when temperatures are lower, in comparison to other, thicker oils. 5w30 helps operate the engine with less drag or friction, providing improved fuel economy and reduce emissions. 5w30 also allows any vehicle to function in all temperature extremes. Additionally, 5w30 has good high-temperature stability and anti-wear performance which increases its lifespan and ensures efficient operation of the engine. 5w30 is a go-to choice for many vehicles due to these key benefits!

What is 10w30?

  • 10w30 is a type of motor oil that has been specifically designed for various types of engines. This oil contains a mix of 10 parts low-viscosity base oil and 30 parts of high-viscosity base oil, providing an ideal solution for modern engines when compared to traditional lubricants.
  • 10w30 is a great choice for many engine types since it’s able to flow better than thicker oils at cold temperatures, protecting against engine wear and tear in colder climates.
  • Additionally, 10w30 also ensures efficient fuel combustion at higher temperatures by providing the necessary lubrication. Thanks to its versatility and optimal performance in various temperature ranges, 10w30 is one of the most popular motor oils on the market today.

Difference Between 5w30 and 10w30

5w30 and 10w30 are two types of motor oil that have distinctly different properties. 5W30 has a lower viscosity, meaning it provides better cold-weather performance and fuel efficiency due to its thin viscosity. 10w30 on the other hand has a higher viscosity which makes it better suited for warmer climates by providing protection while dealing with heat. 5w30 is often used in new cars because it flows easily at lower temperatures, while 10w30 is great for older vehicles with higher mileage since the thicker consistency lubricates and protects more effectively. Both 5w30 and 10w30 offer excellent protection against wear and tear.


If you are not sure which oil is right for your car, consult your owner’s manual or ask a professional. Do not assume that because one brand of oil is recommended for your car that another brand will also work just as well. The same goes for different grades of oil – if the manufacturer recommends 5w30, do not use 10w30 even though it may be a higher grade. Using the wrong type or grade of oil can damage your engine and void your warranty. When in doubt, always err on the side of caution and follow the manufacturer’s recommendations to ensure optimal performance and longevity for your vehicle.
