Can you put 10w 30 in a 5w 20?



Notwithstanding the recommendations of the car manufacturer, mixing 10w30 and 5w20 will not cause any sort of harm to the engine. However, a few drivers claim that it is safer to combine two multi-grade or straight weight oils, rather than mixing multi-grade with straight weight oils.

Is it OK to use 10w30 instead of 5w30?

The answer is yes. You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperature. Generally, the viscosity difference between the two is neglectable.

Can I use 10w30 instead of 5w30 in summer?

Answer: There is absolutely no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine. While some car manufacturers still advocate the use of 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, it is completely unnecessary.

Can you put 10W 30 in 5W?





According to API motor oil guide [1], If you are using 10W–30, you can safely switch to 5W–30 (in car engines). 5W–30 is thinner than 10W–30 when cold. (you must follow the manufacturer’s recommendations). However, switching from 5W–30 to economical 10W–30 is not always recommended.

What oil can I use instead of 5w20?

When 10w30 is used instead of 5w20, probably, only a few changes are discoverable especially when the engine is about to wear out and is old. Moreover, one of the benefits of thinner oil would be to ignite quickly. Therefore, fewer efforts are required to pump the fuel, which minimizes the fuel economy.

Is 5w20 thicker than 10w30?

Main Differences Between 5w20 and 10w30



5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action. Light duty petrol and diesel engines use 5w20, whereas large weight carrying engines need 10w30.

What happens if you put the wrong oil in your engine?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Is 10W-30 better for hot weather?





10W-30 motor oil is recommended for ambient temperatures not exceeding -30°C/-22°F in the winter or 35°C/95°F in the summer. This is a great motor oil to use if you live in Canada or cooler U.S. states. Colder regions would require 5W-20, while hotter regions may call for 10W-40.

Is 5W or 10W better for winter?

When it comes to 5W-20 or 5W-30 vs 10W-30, the opposite is true: the 5W oils will flow a little better in the cold than a 10W oil for maximum cold-weather protection and easier cold starts.

Will thinner oils damage your engine?

Just like using an oil with too high a viscosity may lead to problems in Brad’s engine, using a thinner oil can have the same result. Oil that’s too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

What happens if you mix oil weights?

Can oils of different grades be mixed? The good news is that mixing different types of oil it will not harm your engine in any way in the short run. Most synthetic and semi-synthetic engine oils are based on regular oil and are compatible.



Which oil is better 5w30 or 10w30?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.

What is 10W 30 oil used for?

What is 10w30? 10w30 is a multi-grade engine oil ideal for heavy-load engines because of its ability to withstand hot temperatures for a long time without compromising the performance of the engine. This engine oil has a viscosity grade of 10 in low temperatures and 30 in high temperatures.

Does it really matter what oil I put in my car?

The most important thing is to use oil that’s the right thickness, or viscosity, for your car’s engine. Oil that’s too thick or thin won’t provide the necessary protection for your engine, which can result in costly damage.

Can wrong oil cause knocking?

One of the most common causes of engine knocking is low oil. If your car has been using more oil than usual, it’s a good idea to top it off. You can also try using a higher-quality oil, as this can help reduce engine wear. It’s important to regularly change your oil because dirty oil can also cause knocking.

Which is better 5W-30 or 10w30?

5W-30 multi grade oil is ideal for private vehicles and light-duty petrol and diesel engines. It also provides a better cold temperature start than 10W-30 oil. On the other hand, the slightly thicker oil,10W-30, provides better lubrication for commercial vehicles and heavy-load engine cars.



What is the difference between 5W-30 and 10w30?

Both the oils have similar viscosity at 100 degrees Celsius but 5w30 grade oil will thicken less than 10w30 grade oil in cold climate. This means 5w30 grade oil will flow effectively in low temperatures, whereas 10w30 oil will flow effectively in high temperatures because of the smaller temperature window.

Is 10w30 or 5W-30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.

Is 10w30 good for high mileage?

10W-30 motor oil makes for a decent high-mileage oil. It gives a better fuel economy while reducing the oil consumption for older engines. Older engines with more than 75,000 miles on them require a thicker oil that will properly lubricate their critical engine parts and prevent oil leaks, sludge, and deposits.

Should I use thicker oil in an older engine?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.
