Do-It-Yourself Oil Change: Save Money and Empower Yourself

Home | Blogs | Car Care

Changing your own oil is one of the easiest and most rewarding car maintenance tasks you can do. It saves you money, helps your engine last longer, and gives you a better understanding of how your vehicle works. If you've never done an oil change before—don't worry. This detailed guide from Tool Squire walks you through every step so you can do it confidently and safely.

What You Need for an Oil Change

Before you begin, gather all the tools and materials. Having everything ready will make the process smoother and prevent interruptions.

Basic Tools and Supplies:

Engine Oil – Check your owner’s manual to find the correct type (conventional, synthetic, or blend), viscosity (like 5W-30), and amount.
New Oil Filter – Always replace your oil filter when changing oil. Filters are usually specific to the car’s make and model.
Oil Filter Wrench – A special tool that makes it easier to remove the old filter.
Socket Wrench or Box-End Wrench – For removing the drain plug. Size depends on your vehicle.
Oil Drain Pan – A shallow pan to catch the used oil when it drains from your engine.
Funnel – Helps you pour oil without spilling it all over the engine.
Gloves & Safety Glasses – Used oil can be hot and dirty. Protect your hands and eyes.
Old Rags or Paper Towels – Useful for cleanup and wiping tools.
Jack and Jack Stands or Ramps – You'll need to raise the car to access the oil pan.

Optional but helpful:

Oil filter gasket lube (or just use a bit of new engine oil)
Shop light or flashlight to see under the car

Step-by-Step Instructions: How to Change Your Oil

This process usually takes about 30–60 minutes if it’s your first time. Let’s break it down.

Prepare Your Workspace

Choose a safe, flat location like a driveway or garage. Make sure the ground is level and you have plenty of space to move around.

Let the engine run for 2–3 minutes to warm up the oil. Warm oil drains better.
Turn off the engine and let it sit for 5–10 minutes to cool down just a bit.
Pop the hood and remove the oil filler cap (usually labeled “Engine Oil”)—this helps the oil drain faster later on.

Lift the Vehicle Safely

If your vehicle doesn’t have enough clearance underneath, you’ll need to raise it.

Use car ramps or a hydraulic jack with jack stands.
Never work under a car supported by just a jack—always use jack stands.
Make sure the parking brake is engaged and use wheel chocks behind the back wheels.

Drain the Old Oil

Place the drain pan underneath the oil drain plug (usually located under the engine).

Use the correct socket or box-end wrench to slowly loosen the drain plug. Turn counterclockwise.
Be ready: the oil will start flowing quickly once you remove the plug.
Let all the oil drain into the pan—this may take 5–10 minutes.
Once it’s fully drained, clean the drain plug with a rag and set it aside.

Pro Tip: Keep an eye on the plug washer or gasket. If it's worn out, replace it to prevent leaks.

Remove and Replace the Oil Filter

Locate the oil filter—it’s usually a small cylinder and can be accessed from underneath or from the engine bay.

Use your oil filter wrench to turn it counterclockwise.
Some oil may spill when you remove it, so have your drain pan ready.

Before installing the new filter:

Use your finger to apply a thin layer of new oil to the rubber gasket on the new filter. This helps it seal properly.
Screw the new filter on by hand. It should be snug but not overtightened—usually ¾ of a turn after the gasket touches.

Reinstall the Drain Plug

Carefully screw the drain plug back into the oil pan and tighten it securely (not overly tight—just firm).
Double-check that it’s properly seated to prevent leaks.

Add New Engine Oil

Place your funnel into the oil filler opening on top of the engine.
Slowly pour in the new oil, referencing your owner's manual for the exact amount.
Once done, replace the oil cap and make sure it’s secure.

Start the Engine and Check for Leaks

Start the engine and let it run for 30–60 seconds.
While it runs, check under the car for leaks around the drain plug and oil filter.
Turn off the engine and wait a few minutes to let the oil settle.

Check the Oil Level

Pull out the dipstick, wipe it clean, insert it back in fully, then remove it again to check the oil level.
The oil should be between the two marks (“MIN” and “MAX”) on the stick. If needed, add more oil a little at a time. Don’t overfill.

Dispose of the Old Oil Responsibly

Used oil is hazardous waste and must be disposed of properly.
Pour the used oil into a sealable container (old milk jugs work great).
Take it to an auto parts store, mechanic shop, or household hazardous waste facility that accepts used motor oil.
Never pour oil down the drain, on the ground, or in the trash.

Final Tips for First-Timers

Keep a maintenance log with the date and mileage of your oil change.
Most cars need an oil change every 3,000 to 7,500 miles, depending on the oil type and driving habits.
Double-check that the oil filter and drain plug are tight, and oil level is correct after driving a short distance.

Summary

Doing your own oil change might seem intimidating at first, but with the right tools and a clear process, it’s something anyone can learn. You’ll save money, take better care of your car, and build your confidence with basic car maintenance.
