Do You Check The Engine Oil With The Car Running? 4 Ways to do It [2022]


Learning how to check your oil like a professional is a good way to obtain maximum engine performance and longevity. And while paying attention to the details is an important part of it, the following step-by-step summary includes some of them.

Should I Check My Oil When The Engine Is Hot Or Cold?

It is better to check your oil when the engine is cold. To acquire an accurate reading, park your car on flat ground and turn off the engine for 10 to 15 minutes before checking your oil. Wait a few minutes after the engine has been switched off for the oil to return to the oil pan.

Oil makers used to recommend checking your oil when the engine was cold since this allowed the oil to settle in the pan before it became too cold. It’s critical to have the right amount of oil in your engine to keep it operating smoothly. When your car’s oil level drops, it can cause internal wear and parts to fail prematurely. To maintain your car’s health and efficiency, it’s critical to check your oil regularly.

How To Read Oil Level On Dipstick

To start the process, you need to make sure your car is level; if it isn’t, you won’t be able to get an accurate measurement. Make sure you’re parking on a flat surface to get an accurate readout.

1. Find the dipstick

Turn off the engine and open the hood to get to the oil dipstick. Consult your owner’s handbook if you need assistance finding the dipstick in your engine compartment.

Although it is common to check the oil only when the engine is cool, some newer vehicles do not require this. Check your owner’s manual once more and follow the manufacturer’s instructions.

2. Take out the dipstick

A long metal with a grip loop on top serves as the engine oil dipstick. Pull out the dipstick and prepare a rag or paper towel. When you pull out the dipstick, you can use the paper towel to keep any oil from pouring out of the port. Keep the oil dipstick from being forced out. Grab the loop on the top of the cap and pull.


3. Clean the dipstick

When you pull out the dipstick, you’ll need a paper towel to clean it. The purpose of wiping it clean is to allow you to re-immerse it in the port after pulling it out. When you initially pull out the dipstick, it cannot be easy to judge the reading appropriately.

That is why you must clean it before taking another reading. Start wiping the dipstick from the top and work your way down. However, before wiping the dipstick clean, note the oil’s condition.

4. Get a Reading on Your Oil

You’ll need to re-insert the dipstick after wiping it clean. You take it out again for a second look. The oil level in your car’s engine should be shown on the dipstick by holes, letters, or lines.

It’s F(Full) and L(Less) for some automobiles (Low). For others, these locations are marked by two(or more) little holes or a sequence of lines. To validate what the owners’ manual says regarding the markings on the oil dipstick, you’ll need to consult it again. The lowest marking should be closest to the dipstick’s tip, while the highest should be closer to the cap.

Keynote: You have appropriate engine oil levels if the oil is between these markings. You’ll need to add engine oil if the oil level is close to or below the indicators at the dipstick’s tip. If the oil level exceeds the upper limit, it must be drained and maintained at a normal level.

No Oil On Dipstick?

You’ll need at least one quart of oil if the oil doesn’t reach inside the dipstick’s markings or holes. If the dipstick does not display an oil level, you must immediately add oil.

Valve seals and other seals that fail frequently cause oil spills. They can also come from wear and tear cracks in the engine. When you pour in engine oil, such leaks in the supply lines become outlets for the oil to seep out.

Because your engine has consumed significantly more oil than it should have between the last time you changed the oil and the last time you checked the dipstick, there is no oil on the dipstick while it is cold.

How To Check Engine Oil Level

Insert the dipstick slowly into the tube and push it down to check the engine oil level. Now take it out and examine the tip, which should be covered in oil. If the oil level is between the two lines, your vehicle has enough oil. It’s time to add a quart if it’s at or below the low mark.

  • Make sure your engine is turned off (regardless of the temperature you want).
  • Locate the dipstick under your hood.
  • Remove the dipstick and wipe the oil off.
  • Place the dipstick back into its tube. Make sure it’s all the way in.

Pull out the dipstick and inspect the oil level from both sides. The level is good if the top of the oil streak is between the higher and lower markings.

How Much Oil Should Be On The Dipstick?

Check where the oil ends on the dipstick’s end. If the oil does not reach inside the dipstick’s markings or holes, you will need at least one quart of oil.

If the dipstick does not display an oil level, you must immediately add oil. The amount of make-up oil you should use depends on the age of your automobile, the type of engine it has, the total miles, and the driving circumstances. The dipstick is your indicator of excessive oil use.

Dipstick Oil Level Too High

Checking the oil level with a dipstick is the best way to determine if you have too much oil. Most people use this to ensure they have enough oil, but it can also ensure you don’t have too much.

The “MIN” and “MAX” markings should be present on the dipstick. The oil level should normally fall between those two dipstick markings. However, if the oil level exceeds “MAX,” you have an excess of oil.

It’s possible that the oil level has risen since you last checked or that there is too much oil on the dipstick in some cases. A coolant leak, condensed water (from combustion), or condensed fuel are all possible causes for concern.


Do You Check Your Oil With The Car Running?

I suggest checking the oil level either before starting the engine or 5 to 10 minutes after shutting it down so that all of the oil is in the pan and you can get an accurate reading.

Does It Matter What Oil I Put In My Car?

As a car owner, you need to use oil with the correct consistency for your car’s engine to operate properly. The excessively thick or thin oil will not protect your engine and might cause costly harm.

Is it necessary to let my engine cool before adding oil?

Not at all. Everything is dependent on the vehicle. You may need to examine the owner’s manual to find out. Because different cars have varying temperature needs, it’s important to confirm with your owner’s manual or your mechanic.


If you want your car to stay in good shape, you should never run out of engine oil. The easiest method to ensure this is to keep the correct amount of fuel in your engine. One excellent approach to accomplish this is through dipstick analysis. The oil dipstick is designed to be simple to determine the oil level in your engine.
