How to Do an Oil Change on a Car

Changing your car’s oil might sound like a job for a mechanic, but let me tell you—it’s easier than you think. If you’ve ever made a sandwich or put together furniture from IKEA, you’ve got what it takes to do this. It’s about following steps, being a little patient, and not minding a bit of grease under your nails.

This guide is for folks like us—people who love saving money, want to understand their vehicles better, and enjoy that sweet sense of independence. So, grab your tools, wear something you don’t mind getting dirty, and let’s walk through how to do an oil change on a car the easy way.

Why Changing Your Oil Matters More Than You Think

Now, I know life gets busy. We all delay things. But putting off an oil change is like skipping meals—you’re only hurting yourself (and your wallet) in the long run. Trust me, I’ve been there. I once skipped an oil change for 10,000 miles, and my car sounded like a growling dog every time I started it. Not pretty.

So don’t wait until the engine light screams at you. If your car feels sluggish, or you hear clunky sounds, chances are it’s time. Regular oil changes can:

• Improve gas mileage

• Extend engine life

• Prevent overheating

• Reduce costly repairs

What You’ll Need Before You Get Started

Before we jump into how to do an oil change on a car, let’s talk gear. Imagine you’re getting ready to cook—without the right ingredients, even a simple recipe turns into chaos.

Here’s your checklist:

Quick tip: Always double-check your owner’s manual for the oil type and quantity. Some cars need synthetic oil, others don’t. And nothing’s worse than buying 10W-30 when your car takes 5W-20.

Step 1: Get Your Car Ready

Alright, let’s get into the good stuff. Park your car on a flat surface and make sure the engine is cool—not ice cold, just not hot. You want the oil to flow out smoothly but not burn your hands.

Slide the jack under the car (front center is usually best), raise it, and then place jack stands under each side. Never, and I mean never, rely only on the jack. I learned that the hard way. Safety first.

Pop your hood open, remove the oil filler cap on top of the engine, and take a breath. You’re already making progress.

Step 2: Drain the Old Oil

Now comes the fun part (well, kind of). Crawl under the car with your oil drain pan and place it right beneath the oil drain plug. That’s the big bolt at the bottom of your oil pan. Use your socket wrench to loosen it. Once it’s loose, twist it out by hand and step back—old oil is going to flow out fast.

Give it a few minutes to drain completely. This part is like letting go of the past. Let the old stuff run out, so you can fill it with new energy.

Important tip: Keep a rag nearby. That drain plug will be hot and oily, and it can slip right out of your fingers like a wet bar of soap.

While you’re waiting, take a look around. If you see metal shavings in the oil or a strange smell, that could mean bigger issues. But usually, old oil just looks black and gunky, which is totally normal.

Step 3: Replace the Oil Filter

After the oil has finished draining, it’s time to tackle the oil filter. These are usually on the side of the engine. Twist it off using the oil filter wrench. Some filters can be removed by hand, but they’re often slippery and stuck on tight.

Once it’s off, pour out any oil inside it into your drain pan. Then, take your new filter, dab some fresh oil on the rubber gasket (this helps it seal better), and screw it on snugly—but don’t overtighten. Think “hand-tight and a bit more.”

It’s like putting a lid on a jar. Too loose and it leaks. Too tight and you’ll curse yourself the next time you try to remove it.

Step 4: Add Fresh Engine Oil

Now that everything old is out and the new filter is in, it’s time to add the fresh oil. Place a funnel in the oil filler opening (top of the engine), and pour in the new oil slowly. It’s like pouring maple syrup—don’t rush it or you’ll make a mess.

Use the amount your manual recommends, which is usually between 4-6 quarts for most cars. When you’re done, put the oil cap back on and check under the car. Any drips? If not, you’re golden.

Start the engine and let it run for a minute. Then turn it off and wait about five minutes. Pull out the dipstick, wipe it clean, insert it again, and check the oil level. It should be near the full mark.

Step 5: Dispose of the Old Oil Responsibly

This part might not be exciting, but it’s super important. Don’t pour old oil down the drain or toss it in the trash. It’s toxic and can really mess up the environment.

Most auto parts stores will take it for free. Just pour it into the old oil container or a sealed jug, and drop it off next time you’re out. You’ll feel good knowing you did the job right from start to finish.

Real Talk: Why DIY Oil Changes Are Worth It

I get it. It’s easy to let the shop do it. But when you learn how to do an oil change on a car, you’re not just saving money—you’re gaining confidence. The first time I did it, I spilled oil, got my shirt ruined, and cursed like a sailor. But I also felt proud. It was a moment of “I did this” that no service receipt could match.

Let’s break it down:

• Cost at a shop: $50–$100

• DIY cost: $25–$40

• Savings: Up to $75 per change

And that’s just one change. Multiply that by two or three times a year, and you’re talking serious savings.

How Often Should You Change Your Oil? Here’s the Truth

Let’s get real—this part can be confusing. One person says every 3,000 miles, another says 7,500. Some even say 10,000 if you’re using synthetic oil. So what gives?

The truth is, it depends on your car. Older vehicles, especially those built before 2008, often do need oil changes every 3,000 to 5,000 miles. Newer engines, though, can go much longer. Some have advanced oil life monitoring systems that literally tell you when it’s time.

Here’s a simple breakdown:

Severe conditions include things like frequent short trips, towing heavy loads, or lots of stop-and-go traffic. If that sounds like your commute, change it more often.

I drive a 2017 Honda Civic and usually change mine around 6,500 miles using synthetic oil. It’s the sweet spot between efficiency and engine health. Your owner’s manual or dealership can confirm the best range for your ride.

Warning Signs Your Oil Needs Changing

Sometimes, even when we forget to track mileage, the car speaks. It throws little signs our way like breadcrumbs. We just need to notice them.

Here’s what to watch for:

• Burning smell inside the car

• ⚠️ Check engine or oil light on

• Loud engine noise or knocking

• Dark, thick, or gritty oil on the dipstick

• ️ Engine running hotter than usual

Any of these signs mean it’s time to revisit how to do an oil change on a car, or at the very least, check your oil levels.

I remember once during a road trip in Arizona, the desert heat made my engine run hot and the oil thinned out way too fast. The car didn’t break down, but it sounded like it was gasping for air. Pulled over, checked the oil, and sure enough—it was like syrup. Learned my lesson.

DIY Oil Change Tips From Personal Experience

Over the years, I’ve figured out little hacks and tips that make a world of difference. These aren’t in your manual, but they come from experience—and maybe a few mistakes.

• Warm your engine a bit before draining oil. Not hot, just warm. It flows out easier.

• Always crack open the oil cap first—it prevents suction and speeds up draining.

• Lay down a tarp or cardboard under the car. Oil stains are forever.

• Buy a good funnel—cheap ones leak or wobble.

• Don’t overtighten the drain plug or oil filter. It should be secure, not jammed.

• Keep an extra quart of oil in your trunk for emergencies.

Trust me, these small habits can save you from big messes.

Common Mistakes to Avoid During an Oil Change

Even though learning how to do an oil change on a car isn’t rocket science, there are a few traps you’ll want to dodge. I’ve made some of them—so you don’t have to.

Here’s what not to do:

• ❌ Forgetting to put the drain plug back in before pouring new oil (instant driveway disaster)

• ❌ Using the wrong oil type (can damage the engine or trigger sensors)

• ❌ Not checking the oil level after refill

• ❌ Skipping the oil filter replacement

• ❌ Overfilling the engine with oil (too much is just as bad as too little)

After one particularly rushed oil change, I forgot to tighten the filter. Half a quart leaked onto the driveway by morning. That smell? Oily regret.

So, go slow, double-check, and always keep a rag nearby.

How to Keep Track of Your Oil Changes

Now that you know how to handle oil changes, it’s smart to keep a record. Not just for your own memory, but for when you sell the car. A well-maintained car holds its value better.

Here are a few easy ways to track:

• Notebook in the glovebox

• Oil change apps (like Carfax Car Care or Simply Auto)

• ️ Google Calendar reminders

• ️ Service history printout (for car resale)

I personally use a note in my phone titled “Car Care.” Each time I change the oil, I jot down the date and mileage. Quick, simple, and reliable.

Choosing Between Synthetic and Conventional Oil

You’ve probably seen the debate online. Synthetic oil vs. regular oil—which one wins?

Well, both have their place. Synthetic oil lasts longer, performs better in extreme temps, and protects your engine better. It’s pricier, yes, but often worth it if you drive long distances, in heat or cold, or own a turbocharged engine.

Conventional oil is cheaper and works fine for older, low-mileage cars or drivers who stick close to home.

If in doubt, check your manual. Many modern engines are built to run on full synthetic right from the factory.

Wrapping It Up: Your New Superpower

By now, you’ve got more than just knowledge—you’ve got a new superpower. Knowing how to do an oil change on a car is about self-reliance, saving money, and understanding your vehicle just a little better.

Next time someone at the shop quotes you $89.99 for a “premium oil change,” you’ll smile and say, “Nah, I got this.”

Because you do. You’ve read the steps, seen the pitfalls, and even picked up some insider tips. All you need now is a quiet Saturday morning, some decent music in the background, and a little bit of elbow grease.
