  • ●Drain plug washer or gasket (check if yours is reusable)
  • ●Socket wrench set, oil catch pan, funnel, rags, and gloves
  • ●Jack and jack stands or ramps (if needed for clearance)

Where to find your specs

  • 1.Oil cap — many cars print the viscosity right on it
  • 2.Owner’s manual — lists viscosity, capacity, and filter type

  • 4.Dipstick — confirm the correct level after refilling

Step-by-step oil change

  1. 1
    Warm the engine

    Run it for 3–5 minutes. Warm oil flows out faster.

  2. 2
    Raise and secure the vehicle

    Use jack stands or ramps on level ground.

  3. 3
    Drain the old oil

    Place catch pan under the plug. Loosen with a socket wrench, remove by hand.

  4. 4
    Replace the drain plug washer

    Swap crush washers for new ones. Inspect plug threads.

  5. 5
    Install the new filter

    Wipe the surface. Oil the new gasket. Hand-tighten plus 3/4 turn.

  6. 6
    Reinstall drain plug and refill

    Tighten to spec. Add oil through the filler cap using a funnel.

  7. 7
    Start, check for leaks, verify level

    Run 30–60 seconds. Check underneath. Check dipstick.

  8. 8
    Dispose of old oil properly

    Most auto parts stores accept used oil for free recycling.
