Which is better for your car, 0w40 or 5w30 engine oil? It may seem like an insignificant decision at first glance. However, even if you use the correct engine oil grade, there are still differences in how it impacts your car. Let’s break down the difference between these two grades of engine oil.
5w30 vs 0w40 Table
There are a lot of misconceptions about engine oil, and it’s challenging to know what type you should use. In this table, we will go over the kinds of oils available and their applications so that you can make an informed decision on which type is right for your vehicle!

Here we will discuss why you need to compare before purchasing 0w40 or 5w30 engine oil. One of the most frequently utilized automobile oils is 5W30 oil, which is suitable for many vehicles and engine types. This oil comprises base oils and additives designed to clean the engine while providing superior lubrication.
On the other hand, 0w40 oil is a high-quality engine lubricant with excellent chemical stability and thermal resistance. It can be used in various applications, including turbochargers, cold-weather starting, etc.
What Does 5w30 & 0w40 Means?
What if you need to buy a car and put the oil in yourself? How do you figure out which oil to use and how do you interpret the label? There are various oils; each one is best for specific conditions, so you must get advice from someone who knows what they are talking about. Don’t worry we are here to help you out.
The numbers of those two oils show the viscosity of the oil. The W stands for WINTER. In long answer, The Society of Automotive Engineers (SAE) has a system for how oil is graded. Oils can be graded by number, and they are based on how the oil characteristics.
Multigrade was created to protect a wide range of temperatures since oil’s viscosity varies. This is why you’ll see something like this on the label: SAE 5W-30 or 0W40.
In a 5W-30, the number before the W tells you how thick and thin the oil is. The lower it is, the thicker and thinner it is. It has better cold-temperature performance. Also, in high temperatures, it is thick enough to perform satisfactorily. Multigrade oil is used because it can flow at low temperatures and perform well at high temperatures.
Can You Mix 5w30 And 0w40?
In terms of mixing, it is wiser to mix only the grades, never the brands. These two can be combined. The first one is thicker than the latter, and the added viscosity will ease the startup flow. The temperature is another crucial factor that will decide if you can mix them or not. It is generally hot in Africa, so both of the oil will work fine, but in a colder region like Europe, the 0w will have the upper hand.
What Does 0w40 Use For?
This engine oil is your best friend in extremely cold weather. A look at the numbers will assure you of the allegation. The oil has an unparalleled ability to ease flow to start and enough weight to avoid breakdown. The oil is suitable for diesel and gasoline-powered engines. It is good for everyday vehicles with the industry’s best fuel economy.
Can I Use 0w40 Instead Of 5w30?
You can, but it is not as common of choice. 0W40 oils are generally thinner than the typical 5W30. They may not perform as well in some engines that require more thickness to maintain optimal viscosity at startup and during hotter operating conditions.
It would be best if you kept in mind thick viscosity motor oil works best in hotter areas, and thinner viscosity motor oil works best in colder areas. We see 5w30 thick viscosity than 0W40, so it will work better in hot weather areas. A good rule of thumb is that if your owner’s manual suggests a 0W30, that’s the best option for your car.
The main difference between 0w40 and 5w30 engine oil is that 0w40 engine oil is more suitable for cold and high-performance engines. In contrast, the 5w30 engine oil is suitable for hot weather.
One of these oils is recommended for your vehicle’s engine if you drive in an extremely hot or extremely cold climate. You can mix them if necessary to ensure that both are available.
The 0w40 oil is suitable for all types of vehicles and especially beneficial in cold weather conditions. It is important to consult your owner’s manual to determine the best engine oil for your car.
Frequently Asked Questions (FAQ)
Both Multigrades Motor oil is best used and will work for most applications. The only difference between the two is that 0W40 has a better ability to flow at low temperatures, but this does not mean it doesn’t perform well in high temperatures as well, so if you want an oil that best performance in colder temperatures, then go for 0w40 and if you want an oil with the best performance in the hotter area the go with 5W30.
