Place a jack at the jacking point at the front passenger side on the pinch weld, the thicker metal part just behind the front wheel.

Use the jack to lift the passenger side of the car until you have enough room to work under the car comfortably.

Alternatively, you may drive the front of the car onto wheel ramps. If you do this, be sure to chock the rear wheels.

To make your oil change easier, you may consider jacking the car up as high as it will go.
