If you are used to changing your car’s motor oil regularly, sometimes you might be wondered a common question: Can I use 5W30 instead of 10W30? If you are searching for the answer to the question, then here we have the solution for you.
You might be glad to know that you’re not alone! Many people are still confused about 10W30 vs. 5W30 and what motor oil they should choose for their vehicle. Therefore, we have made all the facts regarding 5W30 or 10W30 motor oil clear to you. So, stay tuned.
What Do Motor Oil Names Mean?
You might be wondering, what does 5W30 mean? Why another motor oil named 10W30? Why are there no other numbers! Well, as much as you are wondering, the fact is more simple than you might be thinking.
For instance, in the name of 5W30 oils, the 5 stands for a specific measurement that indicates how easy you can pour the oil at low temperatures.
If you compare 5W30 motor oil with 10W30, the 5W30 will be poured more efficiently at a low temperature. So, the fact is that a lower number in an oil type indicates lower viscosity that helps to pour quickly into the engine and maintain a better condition.
The second number of 5W30 oil indicates its thickness when it reaches a very high temperature during the operating mode. So, an oil with a more significant number might be the better option if you consider the thickness and engine protection.
Comparison Between 10W30 And 5W30
When you’re hesitating about using 10W30 or 5 w30 oil, a comparison between 10W30 and 5W30 may help you make the fact credible. And so, here we’re going to discuss all significant specifications and advantages of both 10W30 and 5w 30 motor oil.
What is 10W30?
10W30 is a type of engine oil specialized in using in heavy-load engines as it can withstand a more extended period in hot temperatures without compromising the engine performance.
The viscosity grade of this engine oil in low temperatures is 10, and a grade of 30 in higher temperatures makes it the preferable option for heavy-duty engines. The low viscosity of this engine oil at low temperatures indicates that this oil is thin at low temperatures.
Major Specifications of 10W30
There are some specific requirements determined by the American Petroleum Institute, such as ACEA, API SN rating. All these requirements are fulfilled by 10W30 oil. That means the piston on the engine will remain protected from any deposits by the machine itself. These deposits can occur from combustion.
10W30 motor oil has reasonable sludge control. That means it has more resistance to form any gels or undesirable sludge at high temperatures. Moreover, this engine oil is capable of coping with treatment conditions and seals.
According to the European Automobile Association, 10W30 should have an A3/B3 or ACEA A3/B4 rating. This association works for assigning oil sequences by analyzing various specifications of standard engine oils.
Advantages of 10W30
Using 10W30 engine oil has many advantages due to its unique features. 10W30 oil can form a continuous layer that reduces friction between all the parts of the engine. During the stop or start operation, this oil minimize wear and tear that helps to keep the engine cool.
This oil protects different parts of the engine from rust and expands the service life of your vehicle’s engine. While using 10W30 oil in your car, you’ll experience smoother and noiseless gear and clutch operations. In addition, 10W30 has a fantastic ability to maintain its viscosity even at high temperatures.
This motor oil is compatible with different engines no matter how advanced fuels you use to the engine, such as biodiesel and biofuel. Although it is most suitable to use in hot weather, you can still use it in cold weather as well.
What Is 5W30?
So, what is 5W30? 5W30 is another type of multi-grade engine oil used in automobiles. The viscosity grade of this engine oil at low temperatures is 5, and in high temperatures, the grade is 30.
Major Specifications of 5W30
5W30 has fulfilled all the ACEA and API SN requirements, although this can be different depending on the brand oil 5W30 you’re going to use. It is also approved by MB (Mercedes Benz) specification that indicates a specific grade to the motor oil. It is also approved by Volkswagen (VW), Ford oil, and Porsche oil specifications.
Advantages of 5W30
5W30 comes with some outstanding features that make this engine more popular. Same as 10W30, this oil can form a continuous layer that reduces friction between all the machine parts. Its wear and tear reduction capability keeps the engine cool and prevents rusting on different aspects of an engine.
Using 5W30 helps to increase the service life of the vehicle’s engine. This engine oil is much superior in thermal stability. That is why in different temperatures, all the properties of this engine oil will remain the same. In addition, this oil is designed to minimize the consumption of oil. Therefore, you may need a small amount of 5W30 engine oil to maintain good lubrication.
5W30 motor is most preferable for automotive gasoline engines, light-duty diesel engines, and light-duty petrol engines. This oil will give you the best service in cold weather.
What’s The Difference Between 5W30 And 10W30?
Though 5W30 and 10W30 are almost similar in quality, there are still some differences between these two engine oils, especially for their viscosity. This might be why you’re hesitating and a question raising on your mind, can you mix 5W30 and 10W30?. First, let’s have a look at all the facts that differentiate these two engine oils.
The Difference In Name And Meaning
The difference in name is a silly fact, right? But as we mentioned before, there is a deep meaning in such type of name of engine oils and this the reason of establishing a big difference just because of the name.
The name 5W30 or 10W30 represents the grade of viscosity that the Society of Automotive engineers specifies. The “W” in these two engine oils indicates Winter. Both of these engine oils have low viscosity.
However, if you’re confused about which is thicker, 5W30 or 10W30? The answer is 10W30. Generally, 5W30 is much thinner than 10W30 engine oil. This is why 5W30 engine oil is more capable of protecting engine components than 10W30 oil because of its low viscosity.
Due to the similar SAE of both 5W30 and 10W30 engine oils, their performance will be almost the same at high operating temperatures. This is because the last digit 30 of their names indicates viscosity in high temperatures. However, 10W30 becomes thicker in cold seasons, so 5W30 is more suitable for cold climates.
You shouldn’t be surprised to know that the most important thing before choosing an engine oil is to consider where you will use your vehicle. For example, if you’re staying in a region where the climate is cold, you should prefer 5W30, as it performs better in low temperatures. On the other hand, 10W30 works better in high temperatures, so 10W30 is ideal for summer.
If we talk about lubrication, 5W30 will remain one step ahead of 10W30. 5w10 is most suitable for private cars and delight-duty petrol or diesel engines. On the other hand, 10W30 is ideal for heavy-duty vehicles and other vehicles that bear huge load or are used for commercial purposes.
Can I Use 10W30 Instead Of 5W30?
So, now it’s time to decide whether it is ok to use 10W30 instead of 5W30. First, we have analyzed all the differences and similarities of 5W30 and 10W30 engine oils. Next, you have to consider the optimum operating condition of these engine oils, which their viscosity can determine.
Depending on the viscosity, 5W30 will move faster than 10W30 before both oils reach the optimum operating condition. If you’re staying in a cold region, using 10W30 can be a bit problematic to you, as it will take more time to get started.
So, if you’re thinking about using 10W30 instead of 5W30, especially in cold regions, you should reconsider once more. As we recommend, 5W30 will be the best option for you.
If you have no option available and will use 10W30, you might have a hard time starting your engine in a cold climate.
On the other hand, very thick oil can initiate dragging due to high temperatures and a setback to the fuel economy. Alongside, using engine oils with low viscosity can also be a problem as they fly off.
The preferable option is the oil mentioned in your user manual, so follow the instruction of your car’s manufacturer while choosing the engine oil.
Can I use 10W30 instead of 5W30? We have tried our best to present all the information to make a wise decision while choosing your engine’s oil. However, it is clarified that using 10W30 instead of 5W30 won’t be a big issue until you’re living in a cold region, as all the properties of these two engine oils are almost similar.
