Checking your engine oil is one of the simplest, most important things you can do to keep your car healthy — and it takes about five minutes with no tools beyond a rag. Here’s exactly how to do it.

How to check your oil, step by step
- Park on level ground and turn off the engine. Wait a few minutes so the oil drains back into the pan for an accurate reading. (Some manufacturers prefer a warm engine — check your manual.)
- Open the hood and find the dipstick. It usually has a bright, looped handle, often orange or yellow, near the top of the engine.
- Pull the dipstick out and wipe it clean with your rag to remove the old oil film.
- Reinsert it fully, then pull it out again. This gives you a clean, accurate reading.
- Read the level. The oil film should sit between the two marks (often “MIN” and “MAX,” a cross-hatched area, or two dots). Between the marks is good; at or below the lower mark means you’re low.
- Check the oil’s condition. Amber to light brown is normal. Very dark and gritty oil is due for a change; milky or foamy oil can signal a coolant leak and needs a mechanic.
- Top up if needed. Add the oil type listed in your manual in small amounts, waiting and rechecking between pours so you don’t overfill. Then reinsert the dipstick and close the hood.
How often should you check your oil?
Check it at least once a month and before any long road trip. Older or higher-mileage engines that burn oil may need more frequent checks. Topping up is fine between services, but if you’re adding oil often, have the car inspected for a leak or burn-off.
FAQ
Should the engine be hot or cold when checking oil?
Either can work, but the engine should be off and the car on level ground. Wait a few minutes after running so the oil settles. Check your owner’s manual, as a few makers specify a warm check.
What does it mean if my oil is low?
It means the engine has burned or leaked oil since the last top-up. Add the correct oil to bring it between the marks, and watch how quickly it drops — frequent topping up suggests a problem.
What color should healthy engine oil be?
Amber to light brown. Very dark, gritty oil needs changing, and milky or foamy oil should be checked by a mechanic.
