Do you check your oil with the car running? This is a common question among car owners, and the answer may surprise you. While many people assume that checking the oil while the engine is running is a safe and effective practice, it is actually not recommended. In this article, we will explore why it is better to check your oil with the car turned off and discuss the potential risks of doing so while the engine is running.
Checking your oil with the car running can be dangerous for several reasons. First and foremost, the oil is under pressure when the engine is running, which means that it is being circulated throughout the engine at a high rate. This pressure can make it difficult to accurately read the oil level, as the oil may be splashing around or rising and falling as it is being pumped through the engine. This can lead to incorrect readings and a false sense of security regarding the condition of your oil.
Furthermore, checking the oil with the car running can also be harmful to your engine. The hot oil can burn your hands or clothes, and it may also cause steam to rise from the dipstick, which can be dangerous if it comes into contact with your skin. Additionally, the hot oil can also damage the dipstick, which can lead to inaccurate readings in the future.
It is also important to note that the oil is at its highest temperature when the engine is running, which can affect its viscosity. Viscosity is a measure of a fluid’s resistance to flow, and it plays a crucial role in the effectiveness of your engine oil. When the oil is hot, its viscosity changes, which can affect its ability to lubricate the engine components properly. This is why it is essential to check your oil when it is at its normal operating temperature, which is typically when the engine is cold.
So, how should you check your oil? The best practice is to turn off the engine and wait for a few minutes to allow the oil to settle before checking the level. This will ensure that you get an accurate reading and avoid any potential risks associated with checking the oil while the engine is running. It is also a good idea to check your oil regularly, as maintaining the proper oil level is crucial for the longevity and performance of your vehicle.
In conclusion, the answer to the question “Do you check your oil with the car running?” is a resounding no. Checking your oil with the engine running can be dangerous, harmful to your engine, and can lead to inaccurate readings. To ensure the safety and health of your vehicle, it is best to check your oil when the engine is turned off and the oil has settled. Remember, taking the time to do it correctly can save you from costly repairs in the future.
