Why Check Engine Oil When Hot?
Checking engine oil when hot may seem counterintuitive, as most people are taught to check the oil level when the engine is cold. However, there are several reasons why it’s better to check the oil level when the engine is hot.
Firstly, when the engine is hot, the oil is at its most viscous state, which means it’s easier to measure accurately. When the engine is cold, the oil is thicker and more difficult to measure, which can lead to inaccurate readings.
Secondly, checking the oil level when hot allows you to detect any leaks or issues with the oil system more easily. When the engine is hot, the oil is more likely to seep out of any cracks or holes in the engine block or cylinder head, making it easier to spot any problems.
Finally, checking the oil level when hot can help you identify any issues with the oil pump or oil filter more easily. When the engine is hot, the oil pump is working harder to circulate the oil throughout the engine, which can cause any issues with the pump or filter to become more apparent.

Step 1: Make Sure the Engine is Hot
Before you start checking the oil level, make sure the engine is hot. This can take anywhere from 10-30 minutes, depending on the temperature outside and the age of the engine. You can check the oil level when the engine is still warm, but not scorching hot.
Step 2: Find the Oil Dipstick
The next step is to find the oil dipstick. This is usually located under the hood of the car, and is marked with an oil can symbol. If you’re not sure where the oil dipstick is located, consult your car’s manual or look for a sticker on the inside of the hood.
Step 3: Pull Out the Dipstick
Once you’ve found the oil dipstick, pull it out slowly and carefully. Be careful not to touch any of the engine components or wires, as they can be hot and may cause injury.
Step 4: Wipe the Dipstick Clean
Once the dipstick is out, wipe it clean with a lint-free rag or paper towel. This will help remove any dirt or debris that may be on the dipstick, and ensure that you get an accurate reading.
Step 5: Insert the Dipstick and Take a Reading
With the dipstick clean, insert it back into the oil reservoir slowly and carefully. Make sure it’s fully seated before taking a reading. The oil level should be between the “MIN” and “MAX” marks on the dipstick. If it’s below the “MIN” mark, you need to add oil. If it’s above the “MAX” mark, you need to drain some oil.
Step 6: Check the Oil Color and Consistency
While you’re checking the oil level, take a moment to check the color and consistency of the oil. The oil should be a light brown or amber color, and should have a smooth, creamy texture. If it’s dark or dirty, it may be a sign that the oil needs to be changed. (See Also: Why Does My Car Run Out of Oil So Fast – Common Causes Revealed)
