Keeping your engine running smoothly begins with one simple habit—checking the oil. It’s a small task that goes a long way in maintaining your vehicle’s health and avoiding major repair bills. Engine oil keeps the internal components lubricated, minimizes wear and tear, and helps regulate temperature. Neglecting it could lead to engine damage, decreased performance, or even a complete breakdown. Here’s everything you need to know about checking your oil level and doing it right.
Why Checking Your Oil Level is Important
Your engine runs at extremely high speeds and temperatures, generating a lot of friction. Engine oil provides a protective layer between metal parts, reducing that friction and carrying away heat. Over time, however, oil can degrade, burn off, or leak—leaving the engine vulnerable. Checking the oil level helps ensure there’s enough oil circulating to prevent serious mechanical issues. It also gives you a chance to notice any signs of oil contamination, like metal shavings or sludge, which could indicate deeper engine problems.
When to Check Your Car’s Oil Level
Routine checks help you catch issues before they become costly. Ideally, oil levels should be checked:
-
Every couple of weeks, especially in older or high-mileage vehicles
-
Before a long drive or road trip
-
After an oil change, to verify the correct level was added
-
When the oil warning light appears, or if the car feels sluggish or overheated
It’s best to check oil when the engine is cool or has been off for at least 10 minutes. This allows the oil to settle back into the oil pan, giving an accurate reading.
Step-by-Step Guide to Checking Oil Level
Knowing the proper way to check oil level ensures your engine stays healthy and well-lubricated. Follow this step-by-step guide to accurately monitor and maintain your car’s oil levels.
-
Prepare the Car
Park the vehicle on a flat surface and turn off the engine. Wait a few minutes to let the oil settle if you’ve been driving. -
Pop the Hood
Use the hood release lever inside the cabin, usually near the driver’s side footwell. Then, lift the hood and secure it with the prop rod if necessary. -
Locate the Dipstick
The dipstick is often marked with a bright handle—commonly yellow or red. It’s usually located near the front or side of the engine bay. -
Pull and Clean the Dipstick
Remove the dipstick and wipe it clean using a paper towel or cloth. This ensures you start with a clear surface to read the oil level. -
Reinsert the Dipstick
Push the dipstick all the way back into the tube, then pull it out again. Hold it horizontally to check the level. -
Read the Oil Level
Look at the end of the dipstick—there will be markings like “MIN” and “MAX” or two dots/lines. The oil film should be between these markers. Oil below the minimum mark indicates it’s time to top up. -
Check the Condition of the Oil
Besides the level, take note of the oil’s appearance. It should be amber or light brown. If it’s black, gritty, or smells burnt, it may be due for a change.
What to Do if Oil Level is Low
Topping up low oil is straightforward, but requires care:
-
Find the Oil Filler Cap
This cap is often labeled “Engine Oil” and is located on top of the engine. -
Use the Correct Oil Type
Refer to your car’s owner manual for the recommended oil grade (e.g., 5W-30). Using the wrong type can lead to poor performance or damage. -
Pour Slowly and Check Again
Using a funnel, pour small amounts (about 250ml at a time) and recheck the dipstick after each pour. Repeat until the oil is just below the “MAX” line. -
Secure Everything
Tighten the oil cap and make sure the dipstick is back in place. Close the hood securely before driving.
Signs of Low Oil Levels in Your Car
Not every car gives you a clear alert when oil is low, so keep an eye out for these red flags:
-
Oil pressure warning light or check engine light on the dashboard
-
Unusual engine sounds, such as knocking or tapping
-
Blue or smoky exhaust, indicating oil burn-off
-
Excessive engine heat or overheating warnings
-
Increased fuel consumption or sluggish acceleration
If you notice any of these signs, check your oil immediately and address any potential leaks or consumption issues.
Common Mistakes to Avoid When Checking Oil
Even a simple task like checking oil can be done incorrectly. Here are common pitfalls to steer clear of:
-
Checking too soon after turning off the engine: Oil will still be circulating and may give a false low reading.
-
Checking on a slope: Always check on level ground for accuracy.
-
Using dirty rags or cloths: This can contaminate the dipstick or engine.
-
Overfilling the oil: Too much oil can cause foaming, pressure issues, or damage to engine seals.
-
Ignoring oil quality: Even if the level is fine, dirty oil can be harmful. Regularly inspect its color and consistency.
Conclusion
Checking your car’s oil level is a quick, essential practice that every driver should master. It not only ensures your engine stays properly lubricated but also offers insight into the overall health of your vehicle. Done regularly, this simple habit can help prevent breakdowns, extend engine life, and keep your car running at peak performance. Next time you’re near your car, take five minutes to lift the hood and check—your engine will thank you.
