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.
