Maintaining your vehicle is crucial for its longevity and performance, and one of the most fundamental aspects of car maintenance is regularly checking your engine oil. Many drivers feel uncertain about how to check their oil level, but it’s a straightforward process you can easily learn and perform at home. This guide will walk you through the steps of manually checking your car’s oil, ensuring your engine stays properly lubricated and runs smoothly.
Please remember that this is a general guide. Always consult your vehicle’s owner’s manual for specific instructions and recommendations from your car’s manufacturer regarding how to check oil in your particular make and model.
Whether your car is equipped with a modern digital oil monitoring system or relies on the traditional dipstick method, understanding how to manually check your oil is a valuable skill. While newer vehicles often feature dashboard monitors for oil levels, manual checks offer a direct and reliable way to confirm your engine’s oil status. Here are the general steps for checking your car’s oil level using the dipstick:
-
Gather Your Supplies: Before you begin, make sure you have a rag or paper towels readily available. Checking your oil can sometimes get a bit messy, and having these on hand will help you keep things clean.
-
Park on Level Ground: Ensure your car is parked on a flat, level surface. This is important for getting an accurate oil level reading. If your car is on a slope, the oil in the engine will pool unevenly, giving you a false reading.
-
Engine Condition: Cold or Warm? The engine should ideally be turned off before you check the oil. For safety, the engine should be cold to avoid burns from hot engine components. However, some car manufacturers recommend checking the oil when the engine is warm. Refer to your owner’s manual to see if your vehicle has specific recommendations on engine temperature for oil checks. If no specific instructions are given, checking a cold engine is generally a safe and acceptable practice.
-
Locate the Dipstick: Open your car’s hood and find the oil dipstick. It’s typically easy to identify by its bright handle, often orange or yellow, and is usually located prominently near the engine. If you’re unsure, your owner’s manual will pinpoint its exact location.
-
Initial Dipstick Removal and Wipe: Pull the dipstick out completely from its tube. You’ll likely see oil on the end of it. Use your rag or paper towel to wipe the oil completely clean from the dipstick. This initial wipe is crucial for getting an accurate reading on the second dip.
-
Re-insert and Remove Again: Carefully push the dipstick back into its tube, ensuring it’s fully seated. Then, pull it out again for the second time. This second removal is what you’ll use to read the current oil level.
-
Read the Oil Level: Examine the end of the dipstick. It’s designed to indicate the correct oil level in a few common ways. Your dipstick will likely have one of the following types of markings:
- Two Pinholes: These holes indicate the minimum and maximum oil levels. The oil level should be between these two pinholes.
- “L” and “H” Marks: These letters stand for “Low” and “High,” clearly marking the acceptable range. The oil streak should be between the “L” and “H” marks.
- “MIN” and “MAX” Words: Similar to “L” and “H,” “MIN” and “MAX” denote the minimum and maximum levels. Ensure the oil level is within this range.
- Crosshatched Area: Some dipsticks have a crosshatched area. If the top edge of the oil streak is within this crosshatched area, your engine oil level is considered to be at an acceptable level.
If the oil streak on the dipstick is between the high and low marks (or within the crosshatched area), your oil level is generally good. However, if the oil level is at or below the “low” mark (or “MIN” mark, or lower pinhole), it indicates that your car needs more oil.

What to Do If Your Car Needs Oil
If your dipstick reading indicates a low oil level, or if your car’s dashboard oil monitor alerts you, it’s time to add motor oil. It’s essential to use the correct type and grade of oil recommended by your vehicle’s manufacturer. This information is typically found in your owner’s manual and often on a sticker inside the driver’s side doorjamb. Common oil grades include 0W-20 or 5W-30, but always verify the specific recommendation for your car.
If you are unsure about the correct oil type or can’t locate your owner’s manual, visiting a trusted service center like your local Jiffy Lube® is a good option. Trained technicians can quickly access the necessary information and advise you on the right oil for your vehicle.
How to Add Oil to Your Car
If you need to add oil, follow these steps carefully:
-
Prepare to Add Oil: Have a funnel ready to prevent spills and ensure a clean pour.
-
Locate the Oil Filler Cap: Remove the oil filler cap. It’s usually located on top of the engine and is clearly marked with an oil can symbol or words like “Oil” or “Engine Oil.”
-
Add Oil Gradually: Carefully pour oil into the filler opening, using the funnel. It’s crucial to add oil a little at a time. Overfilling your engine with oil can be just as damaging as running it with low oil.
-
Start with Half a Quart: Begin by adding about half a quart (approximately 16 ounces) of oil.
-
Wait and Re-Check: Give the oil a minute or two to settle and drain down into the oil pan. Then, re-check the oil level using the dipstick, following steps 5-7 as described earlier.
-
Add More if Needed: If the oil level is still below or near the minimum mark after adding half a quart, add the remaining half of the quart, or a bit more, and check the dipstick again. Repeat this process of adding small amounts and checking until the oil level reaches the proper range on the dipstick – between the minimum and maximum marks.
-
Replace the Filler Cap: Once the oil level is correct, securely replace the oil filler cap.
How Often Should You Check Your Car Oil?
Checking your car’s oil level should be a regular part of your car care routine. A good rule of thumb is to check your oil at least once a month and ideally before any long road trips. Some experts recommend checking it even more frequently, such as after every two fuel fill-ups. Regular oil checks are a simple yet effective way to proactively monitor your engine’s health and catch potential issues before they become serious problems.

The Importance of Regular Oil Changes
Remember that checking your oil level is only one aspect of engine oil maintenance. Regular oil changes are equally vital. Engine oil degrades over time and use, losing its lubricating properties and accumulating contaminants. Skipping oil changes can lead to increased engine wear, reduced performance, and potentially serious engine damage. Regular oil changes, as recommended by your vehicle manufacturer, are a crucial part of preventative maintenance and help ensure the long-term health and reliability of your car’s engine.
