What Happens If You Use 10w30 Instead Of 5w30_

The question remains, can you use 10w30 instead of 5w30? or what happens if you use 10w30 instead of 5w30? It’s essential to know the manufacturer’s instructions regarding the oil you need to use. The right oil will ensure that your engine does not get easily damaged. It will also maximize fuel economy. Oil with very high viscosity increases temperature causing a drag. If the viscosity is low, the oil will fly off to the internal components. In the end, the engine wears out faster. 

To know if you can alternate the two, you have to ask yourself a question. What is the difference between 5w30 and 10w30 oil? The difference is their cold flow abilities. The numbers 5 and 10 indicate the viscosity of the oil. If the number is low, it means that it is thinner, and it can flow faster. The last name, 30, indicates the thickness. That means that their thickness is similar, but the thinness is different. During a cold start-up, 5w30 oil flows faster since it is thinner than 10w30. If you put them at operating temperatures, their viscosity is similar. Their flow is identical

You can either use 10w30 or 5w30 depending on when and where you are. During winter, it is advisable to use 5w30. You can use 10w30 during the summer. If you live in tropical areas where the temperature is ever high, you can consider using 15w40. 

Why You Need To Change Motor Oil Regularly

It’s essential to change the car oil frequently since it will keep your engine running correctly. The work of the engine oil is to ensure the engine remains lubricated and cool. Without the oil, the moving part would grind against each other. It will cause wear and tear.

Changing your oil will prevent dirt and sludge from building up in your car engine. Unlike the way new oil lubricates the engine, the oil dirty oil doesn’t. It will destroy your engine. You will incur more cost of replacing the engine. 

Lucky oil is not expensive. After traveling for 3000 to 5000 miles, you should change it. Changing it is also easy. 

Here Are Few Steps to Follow if You Want to Add Oil to Your Car

1. Check your oil

If you have been traveling and you suspect the oil is less, don’t check immediately. Allow your vehicle to rest for five minutes, then check. You will not get accurate readings if you check when the engine is still hot. If you travel a lot, you might forget to check the oil. Form a habit of checking the oil every month.

You have to poop the car’s hood and locate the car’s dipstick. After pulling the dipstick, wipe it using a dry cloth. To check the oil, you require reinserting your dipstick and then pulling it out. Check the appearance of your dipstick. Milky oil indicates a coolant leak. You need to take your car to your mechanic as soon as possible.

Also, take it to the mechanic if the oil has metallic particles. Dirty or surge-like oil show you require to change it right away. If you realize that you have to fill in the oil weekly, take the car to your mechanic. It could be leaking. 

2. Choose the Right Oil

Check the manual to know the type of oil the vehicle requires. You need to understand different oil numbers’. You must know oil viscosity by reading the numbers. If the viscosity is high, it means the oil is thicker. That means the oil will not flow smoothly. For instance, 5w30 will flow easily than 10w30. Consider your locality and the season when buying the oil. Avoid oil with high velocity if you live in cold regions. 

If you are not sure about the oil to pick, check the manufacturer’s certification of the oil you require on the manual. Don’t take oil below the standards of the manufacturer’s recommendations.

If you have a high-end car, or you live in a place with extreme conditions, you can use synthetic oil. If your car’s engine operates well on a specific viscosity rating, you should avoid switching it to different multi-weight oil.

3. Add the Oil

You should add the oil once you realize that the reading on the dipstick is below the right level. Even as you add the oil, keep in mind that at some point, you will have to replace it. The manual has instructions on how often you require changing it. When buying oil for your car, check the manual. Unless you have an excellent reason why you need to use a different type, stick to the recommended oil.

Pull your car’s hood and locate your oil fill port. The dipstick will help you know the amount of oil to add. You can add the oil slowly then pause for a minute. Continue until you fill the reservoir. Once you finish, clear the oil off. Ensure the oil doesn’t overflow. To avoid spilling the oil on your car engine, use a funnel.  

If you realize that whenever you want to refill, you must use more than a quart, there could be leakage. If the oil gets dirty, change it right away. Change also after 5,000 miles. 

Assuming you have no clue of the type of oil your car requires, what should you do? You have to Google your car’s model, make, and year. The information will help you to find out the type of oil you should use. When working on your engine, ensure that there are no open flames. Avoid working on the car if the engine is still hot. 


If you have to refill or replace your oil, you have to consider the manufacturer’s recommendation. You also have to consider the viscosity and the season. For instance, you can substitute 5w30 with 10w30 if the temperature is right. If it’s freezing, you should stick to 5w30. Remember refilling the oil can never substitute replacing the oil. You should always replace your oil whenever it gets dirty or the car reaches 5,000 miles. You should never work on your engine if it’s hot or near open flames.
