Changing the oil in a car is a straightforward DIY job if you follow a clear, safe process and use the correct oil and tools for your specific vehicle. Always confirm the oil type, capacity, and service intervals in your owner’s manual before starting.

Quick Scoop

  • You will: warm the engine, safely lift and support the car, drain old oil, swap the filter, and refill with fresh oil.
  • Typical time: about 45–75 minutes your first time, faster once you know your car.
  • Biggest priorities: safety (solid support stands, cool parts) and correct oil spec/amount.

Think of an oil change as a mini health reset for your engine: you’re draining out the “used blood” and giving it a clean, fresh start so it runs cooler, smoother, and lasts longer.

What you need

Keep everything ready before you crack the drain plug so you are not scrambling with hot oil pouring out.

  • Correct engine oil (right viscosity and approval per manual, enough for your engine’s capacity).
  • New oil filter matched to your exact engine.
  • Wrenches or sockets (for drain plug and possibly undertray).
  • Oil filter wrench (often needed to loosen old filter).
  • Oil drain pan large enough for all old oil.
  • Funnel and some rags/paper towels.
  • Floor jack and jack stands or ramps (never rely on a jack alone).
  • Gloves and safety glasses.
  • Optional: torque wrench (for proper drain plug and filter torque) and creeper.

Step‑by‑step: how to change oil in car

1. Prep and warm the engine

  • Park on a flat surface, set the parking brake, and let the engine run a few minutes so the oil gets slightly warm and flows easily (not scorching hot).
  • Shut the engine off, open the hood, and remove the oil fill cap and (often) loosen or remove the dipstick to help oil drain faster.

2. Lift and safely support the car

  • If your drain plug and filter are underneath, raise the front of the car on ramps or with a jack and support it securely on jack stands at the recommended lift points.
  • Double‑check stability by gently rocking the car; if it moves, reset everything before crawling underneath.

3. Locate the oil pan and drain plug

  • Slide under the car with your drain pan and locate the engine oil pan; it’s usually the lowest metal sump on the bottom of the engine, not the transmission.
  • Find the drain plug: a single bolt at the bottom or side of the pan; some vehicles may have two plugs or a protective undertray you must remove first.

4. Drain the old oil

  • Position the drain pan slightly offset from the plug because oil will initially shoot out with some force and arc.
  • Use a wrench or socket to loosen the plug, then remove it by hand while pressing inward to avoid dropping it into the pan; let the oil drain completely (several minutes until it’s down to a slow drip).
  • Inspect the drain plug and washer; replace the crush washer if required by your manual.

5. Reinstall the drain plug

  • Wipe the area around the drain hole with a clean rag so the mating surfaces are clean.
  • Thread the drain plug in by hand first to avoid cross‑threading, then snug it with a wrench to the specified torque (do not overtighten or you can strip the pan or crack the plug).

6. Change the oil filter

  • Move the drain pan under the oil filter because residual oil will spill when you crack it loose.
  • Unscrew the old filter by hand or with an oil filter wrench, keeping it upright as much as possible to minimize mess.
  • Check that the old rubber gasket is not stuck to the engine; if there are two gaskets, the new filter may leak badly.
  • Lightly coat the new filter’s rubber gasket with fresh oil, then spin it on by hand until the gasket touches, and tighten per the instructions on the filter (usually three‑quarters to one turn past contact, or a specified torque for cartridge housings).

7. Lower the car and add new oil

  • If you removed an undertray, reinstall it securely first; then lower the car back onto level ground.
  • Place a funnel in the oil fill hole and pour in about 90–95% of the engine’s specified capacity with the correct oil grade.
  • Wait a moment, then check the dipstick; add oil gradually until the level is between the “min” and “max” marks, ideally near the top without going over.

8. Start engine, check level and leaks

  • Reinstall the oil cap, start the engine, and let it idle 20–30 seconds so the new oil circulates and fills the filter.
  • Shut the engine off, wait a couple of minutes, then recheck the dipstick and top up if needed; also inspect underneath around the drain plug and filter for any fresh oil seepage or drips.
  • If you see leaks, shut the engine off and correct by snugging components to spec; never ignore a fresh leak.

Mini sections: extra tips, safety, and disposal

Safety tips you should not skip

  • Always support the car with stands or ramps; never rely solely on a jack.
  • Wear gloves and eye protection; hot oil and debris can splash when the plug or filter comes loose.
  • Work on a cool enough engine so you do not burn yourself on exhaust components or oil.

How often to change oil

  • Many modern cars can go 8,000–16,000 km (5,000–10,000 miles) or more between changes on synthetic oil, but actual intervals depend on your manufacturer’s schedule and driving style.
  • Short trips, idling, very hot or very cold climates, and towing often justify shorter intervals within your manual’s allowed range.

Proper disposal and environmental note

  • Pour used oil into a sealed container and take it, along with the used filter, to a local auto parts store, recycling center, or municipal hazardous‑waste facility that accepts waste oil.
  • Never dump oil on the ground, in trash, or down drains; it is illegal in many places and a serious environmental contaminant.

Stage Main actions Key checks
Preparation Gather tools, oil, filter; warm engine slightly; open hood and remove oil cap.Confirm correct oil spec and capacity from manual.
Lifting Raise front of car and support with stands or ramps.Vehicle stable, parking brake engaged.
Draining Remove drain plug and drain old oil into pan.Let oil slow to a drip; inspect plug and washer.
Filter Remove old filter, install new pre‑oiled gasket filter.Old gasket not stuck; filter tightened by hand to spec.
Refill Lower car, add fresh oil with funnel, reinstall cap.Dipstick level near “full” but not over max.
Final check Start engine, then recheck level and inspect for leaks.No drips around plug or filter; level correct.
**TL;DR:** To handle _how to change oil in car_ safely, think in this order: prepare tools and correct oil, lift and secure the car, drain old oil, swap the filter, refill to the proper level, then check for leaks and dispose of old oil responsibly.
