Can I Use 10W30 Instead of 5W30: 5 Key Differences

The well-being and long life of your car’s engine are largely based on the kind of oil you choose. The question that “can i use 10W30 instead of 5W30?” is a common one for car owners and fans.

In this guide, we will delve into what these types are, how they function, and provide a detailed answer to this question.

What is 5W30 Oil?

5W30 is a motor oil known for its versatile viscosity characteristics. The ‘5W’ part of its name refers to how the oil performs in cold conditions (the ‘W’ stands for winter). This means that the oil stays reasonably thin, helping your car engine operate smoothly when starting in cold weather. The ’30’ signifies the oil’s viscosity at the typical operating temperature of an engine.

Additionally, this oil checks all the standards for API SN and ACEA. Moreover, the 5W30 has approval from Volkswagen (VW), MB, Porsche, and Ford. Normally, each of these car makers has its oil specifications, and the 5W30 meets them.

What is 10W30 Oil?

Besides, 10W30 is another kind of multi-viscosity oil, like 5W30, but with a slight difference in how it performs in cold temperatures. The ’10W’ indicates that this oil is somewhat thicker, or more viscous, in cold conditions compared to 5W30. This small difference could make 10W30 a better choice for slightly warmer climates, or higher temperatures where the engine doesn’t cool down as much. Additionally, the ’30’ in 10W30, like in 5W30 motor oil.

Moreover, this type also meets several standards. One of these is ACEA, they suggest 10W30 types should have a rating of A3/B4 or A3/B3. In detail, these ratings relate to different features, like its life length and how well it protects your engine.

Furthermore, the API SN rating is another important standard for 10W30 types.

One great thing about the 10W30 is that it doesn’t create any bad sludge when it gets hot. It’s also good to use with treatments and seals, which is a plus.

Differences Between 5W30 and 10W30

When it comes to distinguishing between both types, there are a few key differences to note.


Talking about 5W30 and 10W30, these numbers tell us about the oil’s thickness, or viscosity. ‘5W’ in 5W30 shows that this type is thinner at cold temperatures (the ‘W’ stands for Winter) than 10W30. This means 5W30 is better for cold places, as it flows more easily and quickly in the engine, even if it’s cold, ensuring the engine parts are well-lubricated.

Temperature tolerance

The ’30’ in both 5W30 and 10W30 tells us how the oil run at high temperatures, usually around 100 degrees Celsius, which is often the temperature inside a working engine. Both types work well at this temperature. But, 5W30 can handle a wider range of temperatures than 10W30, meaning it works well even if the weather changes a lot. In contrast, 10W30 is better for places where it’s warm.

Fuel efficiency

Something else to consider is fuel efficiency, how much distance your car can travel on a certain amount of fuel. Usually, 5W30 is more fuel-efficient than 10W30. This is because it’s thinner in cold temperatures, leading to less friction inside the engine. This means the engine doesn’t have to work as hard, saving more fuel.

Oil Performance

Next, both 5W30 and 10W30 can protect your engine and help it run smoothly, but they might work a bit differently in certain conditions. Because 5W30 is thinner, it moves more quickly around your engine when you first start it, giving protection fast. But 10W30, being a bit thicker, might stay stable and perform better when it’s really hot and the engine is working hard.


Besides, both types also stop the metal parts inside your engine from touching each other. But, because 5W30 is thinner when it’s cold, it can quickly get around and oil the engine parts when you start the engine in cold weather. On the other hand, the thicker 10W30 might give better oiling when it’s hot and the engine is under a lot of stress.

Can You Use 10W30 instead of 5W30?

Can i use 10w30 instead of 5w30?, The answer is Yes, you can use 10W30 in a 5W30 engine. They’re similar enough. But remember, it’s not just about the oil’s thickness. Because maybe different cars need different oil weights to run properly.

So, we highly recommend using the oil weight your vehicle’s maker suggests. This helps your engine stay protected and use fuel efficiently. Normally, most car makers say it’s okay to use either 5W30 or 10W30. You can find this in your car’s manual, or if you can’t, just ask the maker!

When You Might Consider Using 10W30 Instead of 5W30

You might prefer 10W30 types over 5W30 at some times. So, in some situations, you can consider changing. For example, if you live in a place that’s usually hot and doesn’t get cold often, 10W30 could be the right choice. This type is a bit thicker when it’s cold compared to 5W30, and this might work better in warm places.

Also, if your car is getting on in years or if the engine seems to use up oil quickly, 10W30 might be a good fit. Specifically, older engines sometimes have larger spaces because of wear and tear, which can cause oil to burn off faster. In this case, the slightly thicker 10W30 could help slow down oil consumption by filling these larger spaces and providing better sealing.

However, it’s usually best to use the type of oil recommended in your car’s owner’s manual. If you’re thinking about using a different type of oil than recommended, it’s best to think about it carefully first.

Engine car


While you can technically use 10W30 instead of 5W30, it’s not always advisable. Always adhere to your vehicle manufacturer’s recommendations and consider your driving conditions to ensure you’re using the best oil for your car’s engine.

The right choice will ensure optimal performance and extend the lifespan of your vehicle.


  1. How to choose the right oil for your vehicle?

    Choosing the right oil for your vehicle involves considering the manufacturer's recommendations, your driving habits, and the climate in which you drive. Remember that the best oil for your vehicle is one that will provide optimal lubrication in all driving conditions.

  2. Can using 10W30 instead of 5W30 damage my engine?

    Yes, it is possible to use 10W30 instead of 5W30 as both types meet the SAE standard. In general, the difference in viscosity between the two types is minimal a. However, it is important to understand that 10W30 oil will flow more slowly than 5W30 in colder environments.

  3. Can using the wrong oil harm my engine?

    Indeed, using the incorrect oil can potentially lead to engine damage. So, it is recommended to have it examined by a professional. The wrong type of engine oil may cause the metal components within your engine to grind against each other. This leads to increased noise and metal particles in your engine oil.
