5w40 vs 10w30 Motor OilThere are a lot of factors to consider when choosing the right motor oil for your car. Do you want to go with a 5w40 or 10w30? What’s the difference, and which is better for your vehicle? In this blog post, we will discuss the pros and cons of both types of oil and help you decide which one is best for you.
5w40 vs 10w30 Table
If you’re like most people, you have no idea what the difference between 5w40 and 10w30 motor oil is. And to be honest, most people don’t need to know. But if you’re the kind of person who likes to be in the know, or if you’re a car enthusiast, then this table is for you!

Main Difference
The main difference between 5w40 and 10w30 Motor Oil is viscosity. Viscosity refers to a fluid’s thickness or resistance to flow. The higher the number, the thicker the oil will be at room temperature (0 degrees Celsius). For example, SAE 30 motor oil will have less viscosity than SAE 40 motor oil when they are both at 0°C but it will be more viscous at higher temperatures.
The viscosity of an oil is measured in centistokes (CST). This means how many seconds it takes for one cubic centimeter of liquid to flow through a specific size orifice under certain conditions. For example, if we have two oils with different viscosities but they both have a reading of 50 CST at 100°C, they will be equal in terms of the thickness or resistance to flow.
What Does 5w30 Mean?
The “w” in a motor oil’s viscosity rating stands for winter. The lower the number, the thinner the oil will be at colder temperatures. This makes it easier to start your car in cold weather. A good example of this is 5w30 motor oil – it will be much thinner than 20w50 when both oils are at 0°C. The number after the W describes how thick the oil is at the engine’s normal operating temperature.
But just because motor oil is thinner at colder temperatures, doesn’t mean that it’s not durable. The “30” in the rating means that the oil has a viscosity of 30 CST at 100°C. This means that the oil will be very thick (resistant to flow) at high temperatures but will still be easy to start your car in cold weather.
What Does 10w30 Mean?

Our Observation
The big difference between 5w40 and 10w30 Motor Oil is the viscosity. The higher the number, the thicker the oil will be at room temperature (0 degrees Celsius). For example, SAE 30 motor oil will have less viscosity than SAE 40 motor oil when they are both at 0°C but it will be more viscous at higher temperatures.

For example, if we have two oils with different viscosities but they both have a reading of 50 CST at 100°C, they will be equal in terms of the thickness or resistance to flow.
Conclusion
10w30 motor oil will be best for people who are looking for an oil that can be used in both cold and hot weather. The “w” means winter so it will flow well at lower temperatures, but the higher viscosity rating of 30 ensures that the oil won’t thin out too much when it heats up inside your engine.
It’s important to remember that there is no perfect motor oil for every situation. You may need to switch to a different weight oil in the summer or winter, depending on how hot or cold it is outside. For example, if you live in a very warm climate, you might want to use 20w50 motor oil during the summer months. Always consult your vehicle’s owner’s manual before changing any fluid.
We hope that you know the difference between them and can decide which one is better for your car. We also think that it’s good to know about motor oils since there are many different types of engine oil out there today with various benefits and drawbacks depending on what kind of vehicle you drive or if you want to use synthetic vs conventional motor oil. We will be covering more about this in future blog posts, so stay tuned!
Frequently Asked Questions (FAQ)
Can I use 5W40 in place of 10w30?
Yes, you can use 5W40 in place of 10w30, but it is not recommended. 5W40 is a thicker oil and will provide better protection for your engine, but it may also cause your engine to run less efficiently. If you are unsure which oil to use, consult your owner’s manual or a qualified mechanic.
