How to change your own oil — and keep $40+ in your pocket every time

Your car's most important maintenance job is also the easiest one to do yourself. A DIY oil change takes about 30–60 minutes, requires tools that cost less than two professional shop visits, and saves you $15–$65 per service depending on where you'd otherwise go.1 This week: everything a first-timer needs to know.

What this actually costs

A quick-lube shop charges $40–$100 per oil change, depending on oil type and your car. Buying oil and a filter yourself typically runs $25–$35 for most vehicles.2 On a conventional oil change, you save around $15–$25. Switch to full synthetic and skip the dealer — you're often looking at $50–$65 in savings per service.

A set of starter tools — oil drain pan, filter wrench, jack stands — runs roughly $50–$80 total, and you use them for every job going forward. Most drivers recover that upfront cost within the first two or three changes.3

What you need before you start

Draining engine oil into a red drain pan with a box-end wrench — Drain plug removal — position your drain pan before loosening 2

Read your owner's manual first. It tells you exactly which oil viscosity your engine requires (e.g., 0W-20, 5W-30, 5W-40), how many quarts, and what filter fits. Using the wrong spec is the one mistake that actually matters.1

Tools list:

Oil drain pan
Box-end wrench (correct size for your drain plug — usually metric)
Oil filter wrench or pliers
Jack and jack stands (or drive-up ramps)
Funnel
Nitrile gloves and rags
New oil filter + correct oil (quantity per your manual)

Most of these live at AutoZone, O'Reilly, or Amazon for under $20 each. The total starter kit is a one-time spend.

Step-by-step overview

Filling an engine with fresh motor oil using a funnel — Refilling with fresh oil after a drain — use the correct viscosity and quantity from your owner's manual 1

Before you begin: If the engine is cold, run it for 5 minutes to warm the oil — warm oil drains faster. If it's already hot, wait 30 minutes before reaching underneath.2

1. Lift and secure the car. Jack up the front, place jack stands under the frame, and lower the car onto the stands. Never work under a car supported only by a floor jack. If your car has enough ground clearance to reach the drain plug, ramps work fine too.

2. Drain the old oil. Slide your drain pan under the oil pan. Use the correct box-end wrench (not an adjustable wrench) to loosen the drain plug counterclockwise, then pull it free quickly — oil comes fast. Let it drain 5 minutes or until it slows to a drip.1

3. Remove the old filter. Locate the oil filter (softball-sized cylinder screwed onto the engine). Loosen it counterclockwise with your filter wrench, let remaining oil drain out, then remove fully. Critical: check that the old rubber gasket (O-ring) came off with the filter. If it stayed behind and you thread on the new filter over it, you'll have a double-gasket seal failure — fresh oil on your garage floor within minutes of startup.1

4. Install the new filter. Dab a thin coat of fresh oil on the new filter's rubber gasket. This helps it seat and seal correctly. Screw on hand-tight, then give it a quarter-turn more. No filter wrench needed for installation.

5. Replace the drain plug. Thread the drain plug back in by hand, then snug it with your box-end wrench. Firm is enough — overtightening strips the threads on the oil pan, which is an expensive fix.2 Many vehicles require a new drain plug washer each time; check your manual.

6. Fill with fresh oil. Lower the car. Open the hood, remove the oil cap (look for the oil-can symbol), insert your funnel, and pour in the amount specified in your manual. Recap the bottle before tossing it so you can count how many you added.

7. Check level and inspect for leaks. Start the engine and let it idle for about 10 seconds to circulate oil. The oil pressure warning light should go off within a few seconds. Shut off the engine, wait 2 minutes, then pull the dipstick: wipe clean, reinsert fully, pull again, and confirm the level reads in the correct range. Look under the car for drips around the drain plug and filter.

Where to dispose of the used oil

Don't pour it down the drain or into the trash. Put used oil in a sealed container (the empty oil bottles work) and drop it off at any AutoZone, O'Reilly Auto Parts, or AutoNation location — they accept it for free and recycle it properly.2 You can also search Earth911.com for a recycling center near you.

Mistake	What goes wrong	How to avoid it
Leaving the old filter gasket on the engine	Double gasket = oil leak on startup	Always confirm the old O-ring came off with the filter
Using an adjustable wrench on the drain plug	Rounds off the plug head	Use the correct-size box-end wrench
Overtightening the drain plug	Strips threads in the oil pan	Snug — not maximum torque
Forgetting to check the oil level after	You may have underfilled	Always dipstick-check before calling it done
Buying the wrong oil viscosity	Engine runs outside spec	Check the owner's manual every time
