The truth is, you can check your vehicle’s oil quickly and easily in under 5 minutes with nothing more than a rag.
This simple step can save you thousands of dollars in repair bills by preventing extensive engine damage & helping keep your vehicle operating smoothly.
But there’s a bit more to it, even though it sounds simple.
- Always make sure the car is on ground level with the engine off before checking the oil.
- Use a cold engine or
wait 5-10 minutes after driving when evaluating oil for the best possible precision. - Most experts recommend checking every month or every 1,000 to 2,000 miles to catch problems early.
- The oil level should be maintained between the low and full marks. If the level is below the low mark, add oil until the level reaches the target.
- Never check oil with the engine running & avoid overfilling to prevent damage.
Why Checking Your Oil Regularly Matters
The lubricant of the moving parts in your engine comes from the engine oil, so regular checks will maintain the life of your engine.
Additionally, lubricating oil will help reduce excessive wear due to metal-to-metal contact, decrease the operating temperature of your engine, and remove any contaminants entering your engine.
The life of engine oil has a limited duration, and a decreasing oil level will lead to early failure of your engine.
Checking your oil on a regular basis will identify possible failures early and will save you thousands of dollars in repairs. Routinely checking oil levels is recommended by all manufacturers. light
Most car owners, however, rely on the oil light for warning of a low oil level (something even I’m guilty of). And by that time, extensive engine damage may have occurred.

Tools You Need to Check Oil
You’ll need the following, which you likely already have available at your home or garage:
- A clean rag or towel to wipe the dipstick with.
- Disposable gloves (recommended).
- A flashlight in low light conditions.
- A funnel to assist with adding oil (if needed).
You will not need any special tools to perform an oil level check. Some newer vehicles now come equipped with electronic oil monitoring systems, but using a dipstick still remains the most reliable method to check oil levels.
How to Check Oil in Your Car: Step-by-Step Guide
It’s time for an oil change, or you just want to check the level. Maybe you reached 5,000 miles on your car, or it’s a completely different reason… Either way, here’s how you can safely check oil in your car:
Park on level ground
Make sure your vehicle has been parked on flat, level ground. Parking on an incline can result in inaccurate oil level readings.
Let the engine cool
For maximum accuracy, check your engine’s oil level while the engine is cold or at least 5 to 10 minutes have passed since you turned off your engine.
Because oil expands when heated, checking the oil level while the engine is still hot may result in reading a higher than actual oil level.
If you are checking your oil level immediately after driving your vehicle, allow the engine to cool for at least 10 minutes before proceeding.
Some engines, such as certain older Chevy V8s, may require up to an hour for oil to settle fully.
Open the hood
To access the engine compartment of most vehicles, locate the hood release lever (generally beneath the driver’s side dashboard) and pull up on it.
Next, locate the safety latch underneath the leading edge of the hood & pull this latch towards you to lift the hood.
Locate dipstick
To access the vehicle’s engine oil dipstick, look for either a yellow or orange handle with the words “ENGINE OIL” printed on the end or an oil can symbol. You can typically find the dipstick towards the front of the engine.
Remove & clean dipstick
To get an accurate level, remove the dipstick completely from the engine and wipe the entire length of the stick with a clean rag or paper towel.
Reinsert & remove the dipstick again
Once you have cleaned the dipstick, push it back into the engine until it clicks into place. Now slowly pull the dipstick from the tube & hold it level until you are ready to read it.
Read the oil level
The oil level must be checked on the vehicle to assess how low/high the engine oil reservoir may be. The dipstick will have markings that identify the minimum & maximum quantity of oil. The oil level is between these two marks.
If below the low mark, add oil. If the oil is above the high mark, you have added too much oil.
Check oil color and condition
The oil may also have discolored due to mileage/hours of engine operation since it was last changed. Oil should be a light amber color with some brown tint after several thousand miles.
If the oil turns brown or black after several thousand miles, there is nothing to be concerned about. Additionally, if the oil is foamy or has a milky appearance, the oil has coolant contamination.
Add oil if necessary
After checking the oil color & level, if the oil level is below the minimum mark, add oil using the exact type specified in your owner’s manual or on the oil filler cap.
You should only add half a quart at a time and wait for a period before rechecking the oil level. If you add too much oil, the engine can be damaged.
Reinsert the dipstick and close the hood
Once finished adding oil, reinsert the dipstick into the correct location, and place the hood back down securely. You are now finished.
I’d recommend checking the oil level again within a couple of days after adding oil to determine if there are any signs of a leaking oil gasket or oil leak.
Hot vs Cold: When to Check Oil
| Engine Condition | Recommended? | Why It Matters |
| Cold (engine off overnight) | Best time | Oil settles; gives the most accurate reading |
| Hot (just driven) | Acceptable | Oil expands; may show a higher level than the actual |
| Running | Never | Dangerous and inaccurate |
If you ask me, the best practice is checking when the engine is cold for reliability. Before checking on a hot engine, wait 5 to 10 minutes after turning off the engine.
How Often Should You Check Your Oil?
Regular monthly checks or every 1,000 to 2,000 miles is best for most vehicles, but check your oil more often if your car has oil-burning problems or you observe unusual symptoms.
Always check the oil before taking a long road trip. Modern vehicles come equipped with oil life monitors that notify drivers when they need to check their oil levels. However, performing manual checks will help identify issues at an earlier stage.
Frequently Asked Questions (FAQs)
Do you check your oil when your car is hot or cold?
Wait at least 5-10 minutes after shutting off your car to check the oil level accurately.
After an engine has been running (whether for long periods of time or short), the oil has heated up and expanded beyond its true level. Therefore, the most accurate way to determine how much oil your vehicle has is to check after it has cooled down.
Is it worse to overfill or underfill oil?
Overfilling oil is the most damaging. An excessive level of oil could cause foaming of engine oil, formation of excessive pressure in the engine oil system, and damage the engine crankshaft and other components.
Under-filled engines can result in premature wear & overheated engines because there is insufficient quantity of oil to absorb & remove heat from the engine. The ideal oil level is always between the low & high marks indicated on the dipstick.
“Typically, an overheating problem has nothing to do with the engine oil and everything to do with the coolant, shares Technical Reviewer at CarParts.com, Richard McCuistian. “If the engine is overheating, stop the vehicle and let the engine cool before you do anything.”
Can low oil cause engine damage?
Yes, if you do not have enough oil, your car will have metal-on-metal friction & create more heat, which will probably lead to a seizure.
How long should a car sit before checking the oil?
If your car is hot, then wait 5 to 10 minutes after turning off the engine to check. If your car is cold, then let it sit overnight before checking. The more time you let your oil sit, the more accurate your results will be.
Can I top up my engine oil when the engine is hot?
Yes, but be cautious when you put oil in a hot engine. It is best to let the oil sit there for 5 to 10 minutes to allow the oil to settle before checking it. Then, slowly add oil.
What happens if you skip oil checks?
If you do not check your oil level, you risk running out of oil, which causes wear & tear on the engine, possibly causing the engine to overheat or completely fail. It will cost you money to fix your engine.
Is it OK to drive with the oil light on?
No, as soon as the oil light comes on, you should immediately pull off the road and check/add oil. If you continue to drive with the oil light on, you could cause extensive damage to your engine in just a matter of minutes.
Do you put the dipstick all the way in?
Yes, you should push the dipstick straight down until it fits very securely in the tube. Then, you can pull it straight out and read your measurement.
How much oil should be on a dipstick?
The oil level should be between the low & full marks on the dipstick. The “safe” zone is typically within 1 or 2 quarts of the low & full marks.
Final Say
Keeping track of your oil levels is one of the simplest ways to maintain your vehicle’s health and prevent costly repair expenses. It costs you five minutes, possibly saves you thousands, and is something you should be doing as part of regular maintenance.
If you find that your oil is leaking frequently, bring your vehicle to a mechanic. In return for taking care of your engine, expect a smooth ride & an extended lifespan for your car.
