Nowadays, car owners are faced with a dilemma involving oil weight. It is being debated whether 0w30 or 0w40 is the right choice. The debate of 0w30 vs 0w40 is fueled by reports that 0w-40 has a longer oil change interval than 0w-30, making it more cost-effective over time.
There are some other differences between these two oils that are worth noting that may help you decide which one to use for your vehicle’s engine. In this article, we will talk about whether or not you should switch from one to the other.
0w-30 vs 0w-40 – short overview
Before we differentiate between 0w30 and 0w40 motor oil, we have to know about their specification and all details first. This is because the two types of motor oils have different capabilities, and the manufacturers recommend that the owner selects the kind of oil-based on their needs.

4 key difference between 0w30 and 0w40 motor oil

Some people wonder what the difference is between 0w30 and 0w40 motor oil. The best way to think about it is that you might want a heavier or lighter-weight oil, depending on the climate in your area.
A thicker, heavier weight oil might be more appropriate in colder climates- this would be a 0w40. Conversely, a lighter-weight crude may be more appropriate in warmer, more temperate climates. This would be a 0w30.
Let’s find out more!
1. Oil Grade
Is it worth the hassle of researching the company’s claims to find out which motor oil is best? First, you might not know that there are two types of motor oils- 0w30 and 0w40. The lower number, also called the weight, indicates how thick an oil is. The higher number, also called the grade, means the oil’s viscosity at a given temperature.
When it comes to cold-weather performance, both motor oils are identical. When the temperature rises, though, things alter.
After the W, the oil’s thinning potential is shown by the numbers that appear on the dipstick. Because of this, the 0w40 motor oil has a higher chance of surviving than the 0w30, which would merely thin out in such high temperatures.
Choosing the viscosity of your engine oil is a concern for most drivers, and rightly so. The engine oil thickness can determine how well it prevents wear on the motor.
As well, thickness determines how it handles under extreme temperature conditions. Most vehicles recommend a 0w30 or 0w40 motor oil, with some requiring 0w20 or 5w20 to manage small engines.
Because they both have the same grade number, the 0w30 and 0w40 are great in cold weather. Even so, the 0w40 edged out the 0w30 in terms of high-temperature performance, with statistics somewhat higher than those of the 0w30.
3. Fuel Economy
As more people are driving cars with smaller engines, the demand for different types of oil is on the rise. People choose 0w30 motor oil over 0w40 because it is lighter and provides a better fuel economy. However, it’s essential to remember that 0w30 motor oil doesn’t offer good protection against wear and tear on the car.
4. Temperature Range
Motor oil is a critical component of a car’s engine. It ensures that the machine is kept lubricated to operate smoothly and without experiencing wear from friction or corrosion from high temperatures.
Moreover, motor oil is classified as either light, medium, or heavy viscosity, depending on its thickness and weight. There are many different types of motor oils available for purchase, but most cars require 0w30 or 0w40 motor oil.
0w30’s maximum kinematic centistokes average temp is 12.5, whereas 0w40’s maximum is 16.3. Therefore, each one has a minimum requirement of 9.3 and 12.5.
frequently asked questions (FAQs)
1. Which is better, 0w30 or 0W-40?
Two digits after the W indicate the motor oil’s potential for thinning at higher temperatures. Because of this, the 0w40 motor oil has a higher chance of surviving than the 0w30, which would thin out in such high temperatures.
2. Can you use 0W-40 instead of 0W-30?
Theoretically, you should utilize 0W-40 instead of 0W-30 in your engine. In cold areas, 0W-30 and 0W-40 oils function as 0W weight oils.
3. Can I mix 0w30 with 0W-40?
It’s OK to use it as a topping.
4. What is 0W-40 oil used for?
They are high-quality, multi-grade oils that use the most advanced synthetic technology and creative additives to keep your engine running smoothly. The oils offer outstanding cold start behavior and good performance. They may be found in a wide range of automobiles and light trucks, both gas, and diesel-powered.
5. What is 0W-30 synthetic oil?
Fully synthetic motor oil in the 0W-30 grade can enhance fuel efficiency.
In conclusion, because the 0w40 has a lower viscosity, it will allow for better engine performance by reducing engine wear and tear. On the other hand, the 0w30 will help keep your car’s engine running cooler but not perform as well because of its thicker consistency.
If you are looking for oil in between Castrol 0W-30 Vs Mobil 1 0w40 that is good for your car’s engine, choose the Mobil 1 0w40. Plus, if you are worried about high temperatures, select the 0w30 oil.
