How to Change the Oil in Your Car: A Step-by-Step Guide from a Greasy-Fingered Enthusiast
If you’ve ever wondered how to change the oil in your car without turning your driveway into an environmental crime scene, you’re in the right place. After two decades of testing everything from econoboxes to super sedans, I still do my own oil changes because it’s quicker than waiting at a lube shop and—honestly—kind of satisfying. This guide shows you exactly how to change the oil in your car, with the little tricks you only learn after spilling a quart or two.
What You’ll Need to Change the Oil in Your Car
- Correct oil grade and quantity (check your owner’s manual or under-hood label)
- New oil filter (cartridge or spin-on) and a new crush washer for the drain plug
- Oil drain pan (10+ quart capacity is safest)
- Socket set/wrench for the drain plug (common sizes: 13mm–19mm, or 1/2"–3/4")
- Oil filter wrench (strap, cap, or pliers style—depends on your car)
- Funnel, nitrile gloves, shop towels/rags, safety glasses
- Ramps or a jack with jack stands, plus wheel chocks
- Torque wrench (handy for the drain plug and some cartridge housings)
Prep: Before You Change the Oil in Your Car
Engines like routine. So do oil changes. Here’s how to set yourself up for success.
- Warm it up mildly: 3–5 minutes of idling or a short drive. Warm oil drains faster; hot oil burns fingers.
- Park on level ground, engage the parking brake, and chock a wheel.
- If needed, raise the front of the car using ramps or a jack and stands. Never crawl under a car supported only by a jack.
- Pop the hood, remove the oil filler cap, and loosen the dipstick. This helps the old oil drain faster.
- Know your capacity: most engines take 4–7 quarts, but check your manual. Guessing leads to overfill—been there.
Step-by-Step: How to Change Oil in Your Car
-
Position the drain pan. Slide it under the oil pan’s drain plug. Give yourself a foot of offset—oil will arc out initially, like a mischievous garden hose.
-
Crack the drain plug. Use the correct socket, turn counterclockwise, and finish by hand. Keep pressure inward while you unscrew so it doesn’t fly into the pan like a torpedo. Let the oil drain completely (a good 5–10 minutes).
-
Swap the crush washer and reinstall the plug. Clean the plug, fit a new washer, and thread it by hand first. Then torque to spec (typically 20–30 lb-ft for many cars, but check your manual). No gorilla arms needed.
-
Remove the oil filter. For a spin-on, loosen with a filter wrench. For a cartridge, remove the housing cap carefully. Have the pan ready—filters can dump a surprising amount of oil. Make sure the old gasket/O-ring isn’t stuck to the engine.
-
Prep and install the new filter. Lightly oil the gasket or new O-ring. If your filter mounts vertically, pre-fill it halfway to reduce dry starts. Hand-tighten a spin-on 3/4 turn after the gasket touches; torque cartridge caps to spec (often 18–25 lb-ft).
-
Refill with fresh oil. Funnel in about 80–90% of the capacity. Replace the filler cap.
-
Start the engine. Let it idle 30–60 seconds. Watch for leaks at the plug and filter. Shut it down, wait 2–3 minutes, then check the dipstick and top up to the full mark.
-
Reset the maintenance reminder. Procedures vary—often it’s in the Settings menu or owner’s manual. Worth doing, unless you like warning lights as décor.
-
Dispose of used oil properly. Pour it into the original jugs and take it to an auto parts store or recycling center. Most accept oil and filters for free.
Oil Types & Capacities Guide for Changing the Oil in Your Car
Use what the engine was designed for, not what your neighbor swears by. Here’s a simple cheat sheet.
| Oil Grade | Where It Shines | Typical Use Case |
|---|---|---|
| 0W-20 | Cold climates, modern fuel-efficient engines | Most late-model Hondas/Toyotas, hybrids |
| 5W-30 | Balanced protection across seasons | Common in midsize sedans and small SUVs |
| 0W-40 / 5W-40 | Higher-temp protection, spirited driving | Performance engines, some European cars |
| 5W-20 / 10W-30 | Milder climates, older vehicles | Legacy domestic and Japanese models |
As for capacity, most four-cylinders take around 4–5 quarts, V6 engines 5–6 quarts, and larger or turbocharged engines can nudge past 6–8. Always verify—engines vary, and overfilling can foam the oil and starve bearings. Not good.
Common Mistakes When You Change the Oil in Your Car
- Overtightening the drain plug or filter (cracked pans and torn gaskets happen).
- Double-gasketing a spin-on filter (old gasket sticks to the block; new one stacks on top—instant leak).
- Wrong oil grade or too little/too much oil.
- Skipping the crush washer—slow drips are the worst kind of driveway art.
- Forgetting a splash shield screw or undertray clip (cue mysterious rattles).
- Working under a car supported only by a jack. Don’t.
Pro tip: Write the oil type and mileage on a piece of tape under the hood. Future-you will thank present-you.
When You Shouldn’t DIY an Oil Change
- Under warranty with free maintenance—no point reinventing the oil pan.
- Exotic undertrays or service modes (some hybrids and European cars require special procedures).
- Stripped drain plug threads or a seized filter—let a pro deal with the headache.
Otherwise? It’s a 30–60 minute job, max. I’ve done it on a lunch break with time left for a coffee that didn’t taste like 5W-30.
Conclusion: How to Change the Oil in Your Car Without the Drama
Learning how to change the oil in your car is one of those simple wins: better engine health, fewer surprises, and the small satisfaction of doing it right. Once you’ve got the hang of it, you’ll be faster than the drive-through places—and you’ll know exactly what’s going into your engine. Gloves off, job done, warning light reset. Feels good, doesn’t it?
FAQ: How to Change the Oil in Your Car
How often should I change my oil?
Follow the maintenance minder or owner’s manual. Many modern cars on synthetic run 7,500–10,000 miles or annually. Short trips or towing? Shorten the interval.
Do I really need to replace the filter every time?
Yes. Oil is the bloodstream; the filter is the kidney. Replace both together for best protection.
Synthetic vs. conventional—what should I use?
Use whatever the manufacturer specifies. Most modern cars call for synthetic. It resists breakdown, especially in heat and stop‑start traffic.
What if I overfill?
If it’s slightly above full, you’re likely okay, but don’t ignore it. Significantly overfilled? Use a fluid extractor through the dipstick tube or crack the plug briefly and drain to correct level.
Why is my oil black right after I change it?
Detergent additives lift carbon and deposits; oil darkening is normal. Focus on interval, level, and leaks—not color alone.
