What’s A Dipstick?
On some cars, you can see two dipsticks, one for engine oil and the other for transmission. However, most cars have only one dipstick. Using a car’s dipstick is a simple and essential tool to check the oil level in a vehicle’s engine. It is a long, thin metal or plastic rod with markings indicating the proper oil level range.
Checking the oil level with a dipstick is straightforward and can help prevent serious damage.
Keeping the oil level within the recommended range is crucial, as both low and high oil levels can cause problems.
- Low oil levels can lead to inadequate lubrication, resulting in friction occurring between engine components.
- High oil levels can cause excess pressure within the engine, leading to oil leaks, increased oil consumption, and potential engine damage.
Engine oil ensures all surfaces run friction-free. Oil adheres to surfaces when cold, so if you check your dipstick with a cold engine, you’ll get an incorrect reading.
Where Do you Find The Dipstick?
Typically, the dipstick is located on the engine block and is easily accessible to the driver. In most cars, the dipstick tube is identified by a brightly colored handle that is easy to spot.
First, open the hood of the car to find the dipstick and locate the engine block.
It is essential to note that the location of the dipstick may vary depending on the vehicle’s make and model. If you are having difficulty locating the dipstick, consult the owner’s manual or seek the help of a professional mechanic.
How Do I Use A Dipstick?
Here’s a quick step-by-step guide on how to use a dipstick:
- Ensure the car engine is turned off and cooled down for at least 10 minutes to let the oil settle.
- Open the hood and locate the dipstick’s brightly colored handle, labeled “Engine Oil” or “Oil Level.
- Remove the dipstick from the tube by pulling it straight out.
- Use a clean cloth or paper towel to wipe off the dipstick’s end and remove excess oil.
- Reinsert the oil dipstick back into the tube, ensuring it is fully seated.
- Pull the dipstick back out and check the oil level. The dipstick will have two marks or lines that indicate the minimum and maximum oil levels. The oil level should be between these two marks.
- If you have less oil than the minimum mark, add more oil to the engine until it reaches the maximum mark.
- Replace the dipstick into the tube and close the hood.
It is essential to check the oil level regularly and add extra oil to ensure that the engine runs smoothly and efficiently. If you notice any problems with the oil level or quality, it’s best to consult a professional mechanic for further inspection and maintenance. (Read Who Makes Motorcraft Oil)
No Oil On Dipstick Possible Causes?

You Just Changed the Engine Oil: If you recently changed the oil, there may not be enough oil in the engine to register on the dipstick. In this case, add more oil until it reaches the appropriate level on the dipstick.
What Happens If There Is No Oil On Dipstick?
If there is no oil on the dipstick, it could cause serious damage to the engine. Adequate lubrication is essential to protect the engine’s moving parts from metal-on-metal contact, leading to excessive wear and tear, increased oil consumption, and even damage.
If you continue to operate your vehicle with no oil on the dipstick, it can result in a seized engine. The check engine light may also come on, indicating a problem with the engine’s oil pressure or oil level. This warning light should never be ignored, and you should add new oil to your car engines as soon as possible to prevent further damage.
If you cannot add oil to the engine yourself or have any doubts about the cause of the low oil level, it’s best to have your vehicle inspected by a professional mechanic. (Read Check Engine Light After Oil Change)
How To Tell Dipstick Is Low On Oil?
To tell you if no oil or the dipstick is low on oil, you should first park your car on a level surface and turn off the engine. Then, wait a few minutes for the oil to settle in the pan. Next, locate the dipstick in the engine bay, usually indicated by a brightly colored handle. Pull the dipstick out and wipe it clean with a lint-free cloth or paper towel.
Insert the dipstick back into the engine and ensure it is fully seated. Then, pull it out again and check the oil level on the end of the dipstick. The oil dipstick level should be between the two marks. If the oil dipstick level is below the “low” mark or there is no oil on the dipstick, then the dipstick is low on oil.
Other indications of low oil on the dipstick include the oil appearing dark and dirty or the oil level being challenging to read due to a lack of clean oil still on the end.
Other Issues For No Oil On Dipstick?
1. No Oil on Dipstick but No Leak
If there is no oil on the dipstick but no visible leaks, it could be due to burned oil or oil consumption.
This means that the oil is being used up by the engine and not retained in the oil pan.
The oil could also leak into the combustion chamber, from the head gasket, or around the cylinder head or the PCV valve, among other engine parts, which could cause severe damage if left unaddressed. Checking for blue smoke from the exhaust or a burning oil smell could be signs of oil burning or consumption.
2. No Oil on Dipstick After Change The Oil
If there is no oil on the dipstick after changing the oil, it is possible that there was not enough oil added during the oil change.
Adding the correct amount of oil recommended for your vehicle is important to avoid any issues. It is also possible that the oil filter was not properly installed or the drain plug was not tightened properly, causing the oil to leak out.
