The Pros and Cons of Checking Oil with the Engine Running
So, should you check your oil with the engine running or not? Let’s weigh the pros and cons of each approach.
Pros of Checking Oil with the Engine Running:
Some mechanics and car owners swear by checking oil with the engine running. Here are some reasons why:
- Convenience: Checking oil with the engine running is often quicker and more convenient than turning off the engine and waiting for it to cool down.
- Accurate Readings: Running the engine allows the oil to circulate and reach its optimal temperature, providing a more accurate reading of the oil level.
- Reduced Risk of Oil Pump Failure: Some argue that checking oil with the engine running reduces the risk of oil pump failure, as the pump is not under the same stress as it would be when the engine is cold.
Cons of Checking Oil with the Engine Running:
However, there are also some potential drawbacks to checking oil with the engine running:
- Increased Risk of Oil Leaks: Running the engine can cause the oil pressure to increase, which may lead to oil leaks or other issues.
- Difficulty in Getting an Accurate Reading: If the engine is not properly warmed up, the oil may not be at its optimal temperature, making it difficult to get an accurate reading.
- Waste of Fuel: Running the engine unnecessarily can waste fuel and increase emissions.

Benefits of Checking Oil with the Engine Off:
Checking oil with the engine off offers several benefits:
- Accurate Readings: When the engine is off, the oil has had time to settle and reach its optimal temperature, providing a more accurate reading of the oil level.
- Reduced Risk of Oil Leaks: With the engine off, the oil pressure is reduced, minimizing the risk of oil leaks or other issues.
- Easy to Get an Accurate Reading: Checking oil with the engine off makes it easier to get an accurate reading, as the oil is not under pressure.
How to Check Oil with the Engine Off:
So, how do you check oil with the engine off? Here’s a step-by-step guide:
- Make sure the engine is turned off and the car is parked on a level surface.
- Locate the oil dipstick under the hood of your car.
- Pull out the dipstick and wipe it clean with a lint-free cloth or paper towel.
- Insert the dipstick back into the oil reservoir and pull it out again. The dipstick will now be coated with oil.
- Check the oil level by looking at the end of the dipstick. The oil level should be between the “MIN” and “MAX” marks on the dipstick.
- Check the oil color. If it’s dark or dirty, it may be a sign that the oil needs to be changed.
Additional Tips and Considerations
Here are some additional tips and considerations to keep in mind when checking oil:
Oil Type and Capacity:
Make sure to check your owner’s manual to see what type of oil your car requires and how much oil it needs. Using the wrong type of oil or overfilling the engine can cause serious damage.
