Can you put 10w30 in a 5W20 engine?

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.

Can I use 10w30 instead of 5w20 in my car?

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.

What's the difference between 10w30 and 5w20?

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 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.

What happens if you put 10W-30 in a 5W-30 engine?

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.

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.
