Owners of other Ford vehicles equipped with the 5.4L engine or the 4.6L V8 may also find this guide to be useful. Some of these vehicles include the Ford F-150 truck, and the Lincoln Navigator SUV.

The owner's manual for this 2003 Ford Expedition recommends using 6 quarts of SAE 5W-20 when changing the motor oil and filter in both the 5.4L V8 and the 4.6L V8 engines.

To complete this oil change procedure, you'll need the following tools: a floor jack, jack stands, a 5/8 or 17mm socket, and an automotive funnel.

Other options include the Royal Purple 20-820, Purolator L24651, Mobil 1 M1-210, K&N HP-2010, Fram PH2, Bosch D3410, AC Delco PF1250, Wix 51372, Champion COS2, Mann-Filter ML 1006 and Motorcraft FL820S.

The 2003-2006 Expedition's jack point is indicated by a small arrow cutout in the metal.

The oil filter (white cylinder in the pictures above) can be seen from underneath the engine and through the front bumper area.

The oil pan drain bolt is located near the rear of the engine's underside.

Removing the oil filler cap from the top of the engine also helps the old oil to drain out faster.

To remove the oil pan drain bolt, use a 5/8" socket and ratchet and turn it counter clockwise.

Be sure to position the oil catch container directly below the oil drain bolt.

I found that a 17mm socket also seemed to fit the oil drain bolt well if you don't have a 5/8 US socket or wrench.

Don't over tighten the oil drain bolt or it may damage the oil pan.

The old oil filter is located closer to the driver side of the vehicle and is mounted horizontally with the round top of the filter facing the front bumper and the threaded open end facing the rear of the Expedition.

If it is too difficult to turn the old oil filter, you may need an oil filter wrench such as the Lisle 63250.

(In a pinch, some people drive a screwdriver into the old oil filter and use that to twist it off. But that is a last resort.)

Some oil will leak out of the old filter, so be sure to have the oil catch container or some rags below the front part of the engine.

I recommend buying the Ford OEM Motorcraft FL820S oil filter since it has excellent reviews on Amazon.

Lubricating the o-ring on the new filter allows it to create a better seal, prevents oil leaks, and makes it easier to remove it during the next oil change.

Don't use an oil filter wrench to tighten the new oil filter or you may damage it or the oil filter receptacle's threads.

So I poured in 5 quarts of oil, ran the engine for a minute, let it sit for a few minutes, and checked the oil level on the dipstick.

Then I slowly added in the sixth quart and repeatedly checked the dipstick until the level reached the "Full" line.

Then I replaced the oil filler cap and the dipstick.

It's a good idea to check the oil level on the dipstick a few times over the next several days and look for any oil leaks on your driveway or garage floor.
