6.0L Power Stroke Oil Change

How to Change the Engine Oil in a 6.0L Power Stroke

Changing the oil in a 6.0L Power Stroke is a fairly simple procedure requiring basic tools and less than an hour of your time. Ford recommends changing the engine oil every 7,500 miles under normal operating conditions and every 5,000 miles under harsh or demanding operating conditions (heavy towing, periods of excessive idling, etc). Since the 6.0L has HEUI injectors, it is extremely important that these intervals do not exceed the manufacturer's specifications.

Applicable Model Years: 2003-2007 Ford Super Duty, 6.0L Power Stroke Diesel
6.0L Power Stroke Oil Filter: Motorcraft FL-2016 (Ford 3C3Z-6731-AA)
6.0L Power Stroke Engine Oil Spec:
15W-40 preferred under most conditions (refer to owners manual for alternatives)
6.0L Power Stroke Engine Oil Capacity:
15 quarts w/ filter


You'll need a 36mm socket with ratchet, 3/4" wrench, torque wrench, oil catch can with minimum 15 quart capacity, a funnel, 15 quarts of motor oil, and a replacement oil filter with new oil filter housing o-ring. Oil resistance gloves are recommended since motor oil is a hazardous waste and can be absorbed through the skin.

It is also highly recommended that a quality synthetic motor oil be used in lieu of a conventional motor oil. The benefits of synthetic fluids significantly offset the higher cost, particularly for 6.0L Power Stroke owners. The Power Stroke's HEUI injection system pressurizes engine oil via a hydraulic pump and uses the high pressure oil to pressurize fuel at the injector. Synthetic motor oils are more resistant to thermal, mechanical, and chemical breakdown in these high demand operating environments, promoting injector life and reducing concerns regarding stiction.

Removing the oil filter

• Park the truck on level ground and allow the engine to cool for at least one hour. Engage the parking brake since you will be working beneath the truck.

• Locate the oil filter housing, the large canister mounted on top of the engine. Using a 36mm socket, remove the cap from the housing; the oil filter will come out with the cap and any oil inside the housing will now drain into the oil pan.


Replacing the oil filter

• Gently remove the used oil filter from the housing lid - it should pop off with a light tug.

• Carefully remove the o-ring from the oil filter housing cap and install the new supplied o-ring.

• The oil filter has a locking snap on one end. Secure this end into the oil filter housing lid; you should feel it snap into place. Set the assembly aside while we drain the engine oil.


Drain plug location and removal

• Position your oil catch can below the drain plug located on the bottom of the engine's oil pan.

• Remove the engine drain plug using a 3/4" wrench. It takes a few minutes to drain 15 quarts, so we'll install the new filter while it drains.

• Liberally lubricate the o-ring on the oil filter housing cap with fresh motor oil - this is to ensure a proper seal during re-installation.


Draining the engine oil

• Install your new oil filter and the oil filter housing lid. Torque the lid to 25 Nm (19 lb-ft) - over-tightening may result in cracking (proceed with caution if you are not using a torque wrench).

• When the engine oil has drained completely, reinstall the engine oil drain plug and torque to approx 30 Nm (20-22 lb-ft). If you do not have a torque wrench, snug the drain plug up tight, but do not apply too much force.


Filling the engine with motor oil

• Add 15 quarts of fresh motor oil (15W-40 for ambient temps above freezing and 15W-30 for temps below freezing) through the engines oil fill (see picture), located on the passenger side of the engine.

• Check the oil dipstick to ensure the crankcase has the correct amount of oil. Start the truck and check for leaks. Recheck the oil level after the engine cools back down.
