How to Check the Oil in Your Car: Step-by-Step Guide for Drivers

Most car problems don’t show up with a drumroll. Running low on oil is one of those issues that can cause serious damage before you even realize what's happening. That’s why knowing how to check the oil in your car isn’t just handy; it’s essential. It takes only a couple of minutes, but it can save you from a repair bill that runs into the thousands.

This guide is written for everyday drivers, not mechanics. We’ll walk through exactly how to check the oil level in your car, what tools you need, how often to check car oil, and the common mistakes people make when using the dipstick. By the end, you’ll feel confident popping the hood and making sure your engine is properly protected.

Why checking engine oil matters

Oil is the lifeblood of your engine. It lubricates moving parts, reduces friction, and prevents overheating. Without enough of it, or if the oil is too dirty, your car can’t run the way it should. Even something as small as skipping a check before a long road trip can turn into a breakdown that ruins your plans.

Fortunately, there is good news! Checking the engine oil level is one of the easiest bits of car maintenance you can do. You don’t need fancy tools or years of experience—just a rag, a steady surface, and a couple of minutes of your time.

When to check car oil

So, how often should you check car oil? Most experts recommend once a month, but it also depends on how and where you drive. Stop-and-go traffic, extreme weather, or towing heavy loads can cause your oil to burn faster.

Here are smart times to check:

• Before long road trips
• If your oil warning light comes on
• After driving in extreme heat or cold
• At least once a month as part of routine care

Tools you’ll need

You don’t need a toolbox to figure out how to check the engine oil level in your car, but you should keep a few basics handy:

• A clean rag or paper towel
• Your car’s owner’s manual (for dipstick location and oil type)
• Ensure you have a level surface to park on.

That’s really it. With those in place, you’re ready to get started.

Here's a step-by-step guide on how to check the oil in your car.

Here’s the process broken down simply.

1. Park on level ground. Make sure your car is turned off and the engine has cooled for at least 5–10 minutes.
2. Open the hood and locate the dipstick. It usually has a brightly colored handle; yellow or orange is common. Your manual will show the exact spot.
3. Wipe it clean. Pull the dipstick out, wipe it with a rag, and reinsert it fully. This action clears old oil streaks and gives you an accurate reading.
4. Remove and read the dipstick. Look at where the oil film lands between the “low” and “full” marks. If it’s below halfway, it’s time to top up.
5. Check the color and consistency. Oil that’s fresh should be smooth and amber. Dark, gritty, or milky oil means it’s time for a change or possibly a mechanic visit.
6. Add oil if needed. If the level is low, add the right type of oil in small amounts and check it often to make sure you don't overfill it.

That’s it; you’ve just completed the process of checking engine oil dipstick readings like a pro.

Interpreting the results

Reading the dipstick is only half the job. Knowing what those results mean is where confidence comes in.

• If the oil is between the marks and looks clean, you’re ready to go.
• If the level is low, add oil slowly, a little at a time.
• If the oil looks dirty, dark, or smells burnt, schedule a full oil change.
• If it looks milky, it could signal coolant mixing with oil, which means you should see a mechanic right away.

According to Consumer Reports’ oil change guide, skipping these checks is one of the fastest ways to shorten an engine’s lifespan.

Avoid common mistakes.

Many drivers think they’re checking correctly, but these simple errors can throw off your results:

• Checking on a slope instead of a flat surface
• Ensure you wipe the dipstick before rechecking.
• Adding oil without looking up the correct type in the manual
• Ignoring the color and only looking at the level

Avoiding these mistakes keeps your checks accurate and prevents unnecessary problems later.

How often to check car oil

You don’t need to obsessively check every morning, but building the habit saves headaches. 

Once a month is a safe rule of thumb, and always before long trips. Some newer cars have electronic oil monitors, but even then, doing a manual dipstick check once in a while is smart. 

Building it into your routine

Think of this as part of your regular car care, just like filling gas or checking tire pressure. It doesn’t take long, and it gives you a quick snapshot of your engine’s health. Over time, you’ll get familiar with how your car’s oil looks when it’s fine versus when it’s ready for a change. That awareness is one of the easiest ways to prevent expensive repairs.

Getting back on the road

Checking your oil only takes a rag, a dipstick, and a few minutes, but it can save you from bigger problems later. Catching issues early means fewer surprises when you’re driving. And if you’d rather leave it to a mechanic, that’s fine too. The important part is knowing how it works and having the confidence that you’re taking care of your car.

Even when you do everything right, cars still break down. Once the factory warranty runs out, it helps to know you’ve got a backup plan. That’s where Chaiz comes in. You can compare several coverage packages and decide which one best fits your budget and driving style.  Many plans also offer roadside assistance, so you won't be left on the shoulder waiting for help when that oil change might be overdue.
