The type of engine oil required by each vehicle is specific to that vehicle. The viscosity and weight of each motor oil are different.
When used in conjunction with a specific brand and type of motor oil, it is also highly recommended. This article will discuss the differences between 10w40 and 20w50 motor oils. Let’s get started now.

What Is the Difference Between 10w40 and 20w50 Oil?
On the basis of viscosity, fuel efficiency, and temperature, we will compare 10w40 and 20w50 oils. Start now.
Viscosity
The 10w40 motor oil has a viscosity grade of ten and a weight of forty. The 20w50 refers to the weight and viscosity grade of the fluid. This indicates that at 100 degrees celsius, a 20 viscosity grade will be half as thick as one at 0 degrees.
Fuel Economy
In terms of fuel economy, the 20w50 motor oil does not outperform the 10w40. There might be no noticeable gain in gas mileage or vehicle performance by changing your oil to 20w50 motor oil if your car has already exceeded 200,000 miles. However, it will maintain your engine running at peak performance.
In terms of high mileage, the 10w40 is no better than the 20w50. This is the main difference between 10W40 and 20W50: 20W50 is thicker.
Hot Weather
In hot weather, the engine oil behaves differently if the temperature is cool rather than warm. Oil thickens when the temperature drops.
Therefore, it will not adequately lubricate. Consequently, high-temperature applications require 20w50 viscosity, while low-temperature applications require 20w50.
Can I Use 10w40 Instead of 20w50?
You can’t generalize because every car is different. It’s important to know what type of motor oil to use for your car based on its age, the time of year, and a variety of other considerations. Damages can be caused by using a 10w40 motor oil in a 20w50 engine for an extended period of time.
When using a 20w50 on a vehicle that requires 10w40, the same rules apply. There are some mechanics that recommend using 10w40 or 20w50 oil, no matter what kind of vehicle you’re currently utilizing. But reading your owner’s handbook and following the manufacturer’s recommendations is the best option.
Accidentally Used 10w40 Instead of 20w50: Is It Ok?
It all depends. There is no need to worry if your vehicle is compatible with 10w40. If the manufacturer advises it, then the 20w50 motor oil should be used.
The 20w50 oil can also be used in engines designed to operate at high temperatures. Other manufacturers’ suggestions suggest utilizing 20w50 in vehicles designed for colder climates. So, if your car is modern and it’s warm outside, you can use 10w40 motor oil.
