How to Read a Dipstick (Even If It’s Hard to See)

Many drivers struggle to check their dipstick accurately, often adding too much or too little oil. Here’s a clear guide to reading a dipstick to ensure you add the correct amount of motor oil without overfilling or underfilling.

Struggling to read your engine dipstick?

Most drivers aren’t familiar with performing basic vehicle maintenance. They typically wait for the check engine light to illuminate on the dashboard before visiting a mechanic.

New and intermediate drivers often feel overwhelmed when they open their vehicle’s hood and see the engine. If maintenance is needed, they usually rely on a professional mechanic.

However, one task many drivers can handle is checking the oil level on the dipstick and adding oil when necessary. For beginners or those with vision challenges, reading the dipstick can be tricky.

That’s why we’ve created a straightforward guide to help you read a dipstick with ease.

How to find and read your engine oil dipstick

Start by grabbing a couple of paper towels from your kitchen. Choose a thick paper product, stronger than a regular tissue.

Next, open your vehicle’s hood and secure it with the hood lift support to prevent it from falling. If your vehicle lacks a lift support, ask someone to hold the hood up for you.

Now, locate the dipstick, typically found near the engine with a yellow or black handle. Place a paper towel or napkin on a flat surface of the vehicle, such as above the license plate area.

Pull the dipstick out and lay it flat on the napkin without wiping it. Gently slide the dipstick to reveal the oil that transfers onto the napkin.

Many find it hard to see the oil level directly on the metallic dipstick. The oil often has a light yellow hue, making it difficult to read.

Using this napkin method, you can clearly see the oil level. Check if the oil is at the full mark, below full, or at the low mark on the dipstick.

If the oil is at or below the “low” or “add” line, you need to add more oil to the engine. Be cautious not to overfill, as this can harm your vehicle.

How to add oil to the oil pan

If the dipstick shows a low oil level, you’ll need to add oil to the oil pan.

First, buy the correct motor oil for your vehicle. You can’t use just any oil or borrow some from a neighbor. Each car requires a specific type of oil to function properly.

Using the wrong oil, whether too thick or too thin, can prevent the engine from running smoothly. While at the auto store, pick up a funnel as well.

With the correct oil in hand, open the hood again, secure it with the lift supports, and locate the cap covering the oil pan’s opening. Insert the funnel into the opening and pour the motor oil slowly.

Avoid pouring the entire oil container unless the oil pan is completely empty. If the oil level is around the halfway mark, add about a third of the container’s contents.

Note: The oil pan is also referred to as the sump in some vehicles.

What happens if the oil pan is too low?

If the sump has insufficient oil for an extended period, your vehicle will show signs that it’s time to add oil to the engine.

These symptoms indicate a serious issue with your vehicle that needs immediate attention.

Oil is critical for a car’s operation. Without enough oil, engine components lack lubrication, causing them to grind and wear against each other.

Signs of low oil levels

● Loud clunking noises – Engine parts need lubrication to move smoothly. Without it, major components may scrape, producing loud clunking sounds.

● Sudden engine overheating – Prolonged low oil levels can cause the engine to overheat, even at a stoplight or right after starting the car.

● Strong burning smell from the engine – A thick burning odor may indicate an oil leak. Oil escaping the pan can drip onto hot engine parts, evaporating and sending a pungent smell into the cabin.

● Oil pressure warning light – Most vehicles have an oil pressure warning light that activates when the sump’s oil level is too low.

If you notice these signs and can’t recall the last time you added oil, top up the motor oil as soon as possible.

Conclusion

Checking an engine oil dipstick can be challenging due to the oil’s light color. By placing the dipstick on a napkin and sliding it gently, you can see the oil level clearly. Compare the mark to the napkin’s oil level to determine if you need to add more.
