Check Engine Oil: Car On or Off?

Checking your engine oil is an important part of routine car maintenance. But should you check it with the car on or off? The answer depends on your car’s make and model.

Car On

Some car manufacturers recommend checking the oil with the engine running. This is because the oil pump is circulating the oil throughout the engine, which gives you a more accurate reading.

If you’re going to check the oil with the engine running, follow these steps:

1. Park the car on a level surface.
2. Turn on the engine and let it idle for a few minutes.
3. Pull out the dipstick and wipe it clean with a paper towel.
4. Reinsert the dipstick and pull it out again.
5. Check the oil level on the dipstick. The oil should be between the “min” and “max” marks.

Car Off

Other car manufacturers recommend checking the oil with the engine off. This is because the oil has settled to the bottom of the engine, which gives you a more accurate reading of the oil level.

If you’re going to check the oil with the engine off, follow these steps:

1. Park the car on a level surface.
2. Turn off the engine and wait a few minutes for the oil to settle.
3. Pull out the dipstick and wipe it clean with a paper towel.
4. Reinsert the dipstick and pull it out again.
5. Check the oil level on the dipstick. The oil should be between the “min” and “max” marks.

Which Method Is Better?

Ultimately, the best way to check your engine oil is to follow the recommendations in your car’s owner’s manual.

If you’re not sure whether to check the oil with the engine on or off, it’s always a good idea to err on the side of caution and check it with the engine off.

Tips for Checking Engine Oil

• Check the oil regularly, especially before long trips.
• If the oil level is low, add oil until it reaches the “max” mark on the dipstick.
• If the oil is dark or dirty, it’s time for an oil change.
• If you see any metal shavings or other debris on the dipstick, it’s a sign of a serious problem and you should take your car to a mechanic immediately.
