Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is cool.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Drain Old Oil

Tools Required: Socket set, oil catch pan, funnel, rags
Place the oil catch pan under the oil pan.
Remove the oil drain plug using the socket set and allow the old oil to fully drain into the pan.
Clean the drain plug and replace the washer if necessary.

3. Replace Oil Filter

Remove the old oil filter using an oil filter wrench.
Apply a small amount of new oil on the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

4. Add New Oil

Reinstall the oil drain plug and tighten it to the manufacturer's specified torque (typically around 30 ft-lbs).
Using a funnel, pour the appropriate type and amount of new oil into the engine (typically 5-6 quarts of 0W-20 synthetic oil for the Highlander).
Check the oil level on the dipstick and add more oil if necessary.

5. Final Checks

Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.
Turn off the engine and check the oil level again, adding oil if necessary.
