5w40 vs 10w40, which one should you choose? Well, you may want to read this article before making up your mind. Certainly there is some difference between 5w40 and 10w40 oil and after reading this post you should know if you can use 10w40 instead of 5w40 for your vehicle. Last week we compared 5w20 vs 5w30 in a detailed post showing you which one to use for your vehicle.

There are many different types of oil available on the market to choose from, but not all of them may be safe to use in your vehicle. This makes it difficult for most car owners to make the right choice among the large number of motor oils. Different motor oils come in different types for specific applications.

Using the wrong motor oil can damage your engine, and the similar numerical characters these oils come with make it even more confusing to choose the right one for your car. Most car owners don’t even care about the issue of changing the oil in their vehicles.

This is because they take their vehicles to the garage for an oil change and allow their mechanics to choose the most suitable one for their cars. Some people can peruse the Internet and look for the oil that their manufacturer recommends.

What grade of motor oil should I use between 5w40 and 10w40?

In order for you to make the right choice, we need to compare the properties and specifications of motor oils so that you can know which is the correct oil to use in your car.

What do the numbers attached to the motor oil mean?

  • Take for example 5W40 and 10W40, the numbers 5, 10 and 40 represent the viscosity of the oil, while the W represents winter.
  • The code number system was established by the Society of Automotive Engineers (SAE).
  • They use this code to classify motor oils based on their viscosity characteristic.
  • Various grades of oil were set to provide protection to the engine at different temperatures due to the fact that the viscosity of the oil changes with the change in temperature.
  • For this reason, the oil label indicates SAE 5W30, or SAE 5W20, or SAE 5W40, or SAE, 10W40, and others.
  • The number before the W represents the oil’s viscosity when temperatures are at their lowest.
  • A lower number indicates a more dilute oil and is therefore better for a cold start or cold temperatures.
  • The number after the W indicates the thickness of the oil when the engine is operating at normal temperatures.
  • According to SAE, x and y can be represented by viscosity characteristics ranging from 0, 5, 10, 15, 20, 25, 30, 40, 50, and 60.
  • Thin / liquid / lower viscosity oils are typically given a lower viscosity while those that are consistent and very thick are given a high value.
  • For a 10W-40, the number “10” specifies 10 degrees Celsius; the “W” is for winter, which means that the oil should function and start the vehicle properly when the outside temperature is 10 degrees Celsius (50 degrees Fahrenheit) during winter. The second number (40) determines the thickness of the oil while it is under the heat of a running engine.
  • A higher number means the thickness of the oil under heat.

Characteristics of 5W40 motor oil

5W-40 is a thin motor oil, which means it will easily reach the moving parts of a vehicle and lubricate itself as you try to start it. The “40” shows that this oil is slightly thicker than the average motor oil, which is generally 30 for most cars, and will oil the engine more than average while it is hot.

5W40 motor oil applications

Since 5W40 is thicker under heat than an average oil, most mechanics commonly use 5W-40 motor oil to support higher mileage engines. This oil tends to better lubricate moving parts within the engine that have worn down due to the passage of time.

5W40 motor oil is used in high-mileage vehicles in climates that experience 5-degree Celsius (41-degree Fahrenheit) winters. This oil is reliable for cold engine starting, but may not be very effective in subzero climates.
