Low engine oil is one of the fastest ways to destroy an engine — and most people don’t realize there’s a problem until it’s too late. Knowing how to check your car oil takes less than five minutes and can save you thousands of dollars in engine repairs. Here’s exactly how to read the dipstick correctly, step by step, even if you’ve never popped a hood before.
What You Need to Know Before You Check Your Oil
- Always wait 5–10 minutes after turning the engine off before checking — oil needs time to drain back down into the pan for an accurate reading
- Wipe the dipstick clean before reading it — checking the oil on a cold pull gives you a false reading
- Oil that looks milky, extremely dark, or gritty isn’t just low — it may signal a bigger engine problem that needs attention

The Short Answer: Pull the Dipstick, Wipe It, Dip It Again, Then Read It
To check your oil dipstick:
- Park the car on a flat surface
- Turn the engine off and wait a few minutes
- Open the hood Find the oil dipstick (usually yellow or orange)
- Pull the dipstick out
- Wipe the dipstick clean on a paper towel
- Put the dipstick fully back in
- Pull it back out and check the oil level
- Add oil if the level is low
What You’ll Need
- A paper towel, rag, or napkin
- Engine oil if the level is low
Step 1: Park the Car and Turn It Off
Park your car on a flat surface.
Turn the engine off and wait about 5–10 minutes so the oil can settle back into the engine.
Do not check the oil immediately after shutting the car off.
Step 2: Open the Hood
Pull the hood release lever inside the car.
Go to the front of the vehicle, release the safety latch, and lift the hood.
Secure the hood before checking anything.
Step 3: Find the Oil Dipstick
Look for a long handle sticking out of the engine.
The oil dipstick handle is usually:
- Yellow
- Orange
- Marked with an oil can symbol
Do not confuse it with:
- The transmission dipstick
- Coolant caps
- Washer fluid caps
Step 4: Pull Out the Dipstick
Slowly pull the dipstick all the way out.
The bottom of the dipstick will have oil on it.
Step 5: Wipe the Dipstick Clean
Use a paper towel or rag to wipe all the oil off the dipstick.
This helps you get an accurate reading.
Step 6: Put the Dipstick Back In
Push the dipstick fully back into the tube.
Make sure it goes all the way in.
Step 7: Pull the Dipstick Back Out and Check the Oil Level
Pull the dipstick back out again and look at the oil near the tip.
Most dipsticks have:
- Two dots
- Crosshatch marks
- MIN and MAX lines
The oil level should be:
- Between the marks
- Closer to FULL or MAX
If the oil is below the minimum mark, your engine may need oil.
Step 8: Check the Oil Condition
Healthy oil usually looks:
- Amber
- Light brown
- Smooth
Oil that looks:
- Extremely dark
- Thick
- Gritty
- Milky
may indicate the oil needs changing or there could be an engine problem.

How to Check It Correctly and Avoid Common Mistakes
Do not overfill the engine with oil.
Always use the oil type recommended in your owner’s manual.
If your oil level keeps dropping quickly, your engine may have a leak or be burning oil.
Signs Your Oil May Be Low
- Oil warning light
- Engine ticking noises
- Burning oil smell
- Rough engine performance
- Engine overheating
How to Read What Your Dipstick Is Actually Telling You
| What you see on the dipstick | What it means |
|---|---|
| Level between MIN and MAX, amber color | Oil is fine — no action needed |
| Level near or below MIN, amber color | Add oil to bring it up to MAX |
| Level is fine but oil is very dark | Oil change is overdue |
| Level keeps dropping between checks | Engine may be leaking or burning oil |
| Milky or foamy oil at any level | Possible coolant leak into the engine — get it inspected immediately |
How to Check It Correctly and Avoid Common Mistakes
- Never overfill the engine with oil. Too much oil is just as harmful as too little — it can cause foaming, pressure buildup, and seal damage. Add small amounts at a time and recheck between additions.
- Always use the oil type your owner’s manual recommends. The wrong viscosity can reduce protection and void a warranty. The correct grade is also printed on the oil cap on most vehicles.
- Check your oil once a month. It takes two minutes and catches low levels before they damage the engine.
- If oil keeps dropping quickly between checks, the engine may have a leak or be burning oil internally. Both need attention — topping up repeatedly without finding the cause isn’t a fix.
- Check oil when the engine is cold or after it has sat for at least five minutes — never check immediately after shutting off a hot engine.
What to Do If Something Looks Wrong With Your Oil
Oil level looks different every time I check. Make sure you’re waiting the full 5–10 minutes after shutting off, pushing the dipstick all the way in before the final pull, and reading on a flat surface. Any of those factors can cause inconsistent readings.
Oil looks fine on the dipstick but the oil warning light is on. The oil pressure warning light doesn’t always mean the level is low — it can indicate low oil pressure even with adequate oil in the engine. Have it inspected promptly. Driving with low oil pressure causes rapid engine damage.
Oil level was fine last month but is now near the minimum. Some oil consumption between changes is normal, especially in older engines. Losing more than a quart every 1,000 miles is considered excessive — have the engine checked for leaks or oil burning.
Milky or foamy oil on the dipstick. This usually means coolant is mixing with the oil — often from a blown head gasket. Don’t keep driving. Have it inspected immediately — this can cause serious internal engine damage quickly.
Not sure which dipstick is the oil dipstick. Check your owner’s manual — it has a diagram showing the exact location. Most oil dipsticks are yellow or orange. If the handle has an oil can symbol on it, that’s the one.
Frequently Asked Questions
How often should I check my car’s oil? Once a month is a good habit for most drivers. Check it more frequently if the car is older, has higher mileage, or if you’ve noticed the oil level dropping between checks.
Do I check oil with the engine on or off? Always with the engine off — and after letting it sit for at least 5–10 minutes. Checking with a hot running engine gives an inaccurate reading and risks burns from hot engine components.
What does it mean if my oil is very dark? Dark oil usually means it’s overdue for a change. Oil darkens as it picks up combustion byproducts and contaminants over time. Very black, thick, or gritty oil needs changing soon. Milky oil is a different and more serious issue.
How much oil should I add if it’s low? Add oil in small amounts — about half a quart at a time — then recheck the dipstick before adding more. It’s easy to overfill, and too much oil causes its own problems.
What type of oil does my car take? Check the owner’s manual or the oil cap under the hood — most caps have the recommended oil grade printed directly on them. Common grades include 5W-30 and 0W-20, but the correct grade depends on your specific vehicle.
