If you’re wondering whether you can use 10W30 oil instead of 5W20 in your car, the answer is maybe. 10W30 is a thicker oil than 5W20, so it may provide better protection for your engine, but it also may not work as well in cold weather. You should check your owner’s manual to see what weight of oil is recommended for your car.

You can use 10W30 Instead of 5W20 easily-

  • Drain the oil from your car using the proper tools and techniques
  • Refill the oil pan with 10W30 motor oil
  • Clean and reinstall the oil filter, making sure to use the correct replacement filter for your vehicle model
  • Reattach all hoses and components that were removed during the process
  • Start up the engine and check for any leaks around the newly installed parts

What is the Closest Oil to 5W20?

The closest oil to 5w20 is 10w30. This oil has a similar viscosity and weight, making it a good choice for those who want to use 5w20 oil in their vehicles. However, it is important to note that 10w30 oil may not be suitable for all vehicles, so it is always best to consult your owner’s manual or a qualified mechanic before making the switch.

Can I Put 10W30 in 5W 30?

You might be able to get away with using 10w30 oil in a 5w30 engine, but it’s not recommended. The main difference between the two oils is their viscosity or thickness. 5w30 oil is designed to flow more easily at lower temperatures than 10w30 oil.

This means that it will reach all of the engine’s moving parts more quickly when you first start up your car, and can help protect against wear. It also helps improve fuel economy since it doesn’t have to work as hard to lubricate the engine. However, using a thicker oil like 10w30 in a 5w30 engine can cause some problems.

The oil may not flow as easily and could lead to increased wear on engine parts. It can also make starting your car more difficult in cold weather. So while you might be able to get away with using 10w30 oil in a 5w30 engine, it’s not something that we would recommend doing on a regular basis.

What Can I Replace 5W-20 With?

Most carmakers recommend using 5W-20 motor oil in their vehicles, but what happens if you can’t find that weight of oil or you run out of it and need to top off your engine? Can you use a different viscosity oil as a substitute? The short answer is yes, you can use a different viscosity motor oil as a replacement for 5W-20, but there are some things to keep in mind.

First, remember that the numbers in motor oil weights (5W, 10W, etc.) refer to cold weather performance. The lower the number, the easier it will be for the oil to flow when it’s cold outside. So if you’re using 10W-30 as a substitute for 5W-20 in wintertime, your engine might not get the same level of protection at start-up as it would with the thinner oil.

Similarly, 20-weight oils tend to flow more readily than heavier 30 or 40-weight oils when it’s hot outside. So if you’re using 5W-30 or 5W-40 as a stand-in for 5W-20 during the summer months, your engine might not get the same level of protection against heat and wear. In general, it’s best to stick with the recommended motor oil weight for your vehicle unless you have a good reason not to.

But if you do need to make a substitution, choose an oil that has a similar viscosity rating (5w-, 10w-, etc.) and try to stay within +/-2 points on the second number (the “20” in 5W-20).

Accidentally Put 10W30 Instead of 5W20

If you accidentally put 10W30 oil instead of 5W20 in your car, don’t panic. Although the two oils are similar, they are not interchangeable. 10W30 is a thicker oil that is designed for use in higher temperatures.

It will provide better protection for your engine in hot weather conditions. 5W20 is a thinner oil that is best used in cooler temperatures. It will help to improve fuel economy and reduce engine wear in colder climates.

If you live in an area with extreme temperature changes, it’s best to use synthetic oil that can be used throughout the year. However, if you only use your car in moderate conditions, either 10W30 or 5W20 will work just fine.


As long as the 10W30 oil meets the standards set for 5W20 oil, you should be fine using it instead. Check your owner’s manual to see what oil weight is recommended for your car.
