Can I switch from 5w20 to 10w30?

The 5 and 10 digits signify the viscosity of the oil at lower temperatures. So, this means that when you are asking can you use 10w30 instead of 5w20, the thinner 5w20 will circulate faster, and move better across bearing tolerance during ignition in the winter or cooler climates.

Is it OK to use 10w30 instead of 5w20?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won't spray your lower cylinders for an extra second or so on each cold start.

Can you put 10w30 in a car that takes 5W 30?

Synthetic oils will mix perfectly, as long as they have the same chemical composition. As a result, mixing 10w30 and 5w30 is not a problem since one will be topping up. It is not harmful to mix engine oils because 5w30 and 10w30 engine oils have close viscosity, so mixing them is not harmful.

Can I mix 5w20 and 10w30?

It should be fine, considering the temps, and that the suggested oil viscosity is usually 5W-30, so two quarts of 5W-20 and three of 10W-30 probably come pretty close to some viscosity around 5W-30.

Which is better 5w20 or 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.

Is it OK to top off oil with different weight?

There will be no problem with that. There will be no harm done as they mix right in. You will be fine even if you mix syn with conventional. If you were to labratory test your oil, it would read out as not a true 10W-30, but there will be no harm.

Is 10W30 thicker than 5w20?

Thicker and heavier, 10w30 protects older engines with its great healing properties. Multi-grade oil 5w20 is thinner in comparison and best for quick ignitions in lower temperatures. To maintain the perfect condition, your vehicle should only receive specified motor oils from the manufacturers.

Is 10W30 better 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.

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

The main difference between 5w30 and 10w30 is that 5w30 is less viscous and more efficient than 10w30 because the fuel is thinner and can reach the difficult part of the engine. 5w30 is a viscosity engine oil that is used for engine lubrication.

What happens if you use the wrong oil weight?

Using the wrong motor oil viscosity, especially if thicker than recommended, will directly affect your car's mileage. This is because critical moving parts, like pistons, move less freely. This adds a load onto the engine and subsequently reduces the car's overall fuel efficiency.

Is 10W30 good for winter?

10W30 vs 10W40 Oil FAQs

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.

Will using the wrong oil hurt my car?

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.

What oil can I substitute for 5W-20?

As 5W-20 is a low viscosity oil, it's best suited for cars that drive a lot in low temperatures and colder climates. It's ideally recommended for light-duty petrol and gasoline engines, and can help with engine deposits and wear and tear problems. For a higher temperature climate, you may use 10W-30 as an alternative.

Is it OK to use 10w40 instead of 5w20?

mileage and lubrication is not as good plus it puts more strain on the oil pump. Never go thicker than a 5w30 and that would be more for an older higher mileage engine in warmer climates. So go change it back to 5w20.
