6.0L Power Stroke Oil Change Tutorial

Changing 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 about an hour of your time. Ford recommends changing the engine oil every 7500 miles under normal operating conditions and every 5000 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 you do not exceed these oil change intervals or injector damage may occur. Required tools: 36mm socket with rachet, 3/4" wrench, torque wrench (recommended, but not required to perform an oil change), oil catch can with min. 15 quart capacity, a funnel, 15 quarts of motor oil, and a replacement oil filter with new oil filter housing o-ring. It is also recommended that you wear oil resistant gloves since engine oil is a known cancer-causing substance.


• Park the truck on level ground and allow the engine to cool for at least 1 hour (draining hot oil is no fun). 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 (see pictures below). 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.

• Gently remove the used oil filter from the housing cap - 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 cap; you should feel it snap into place. Set the assembly aside while we drain the engine oil.

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

• 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 on the o-ring.

• Install your new oil filter and the oil filter housing cap. Torque the cap to 25 Nm (19 lb-ft) - overtightening may result in cracking the cap (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.

• 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 below), 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.

Remove the oil filter cap to gain access to the oil filter. Remove the used oil filter & oil filter seal. Snap the new filter into place & install the new o-ring. Using a closed ended wrench, remove the drain plug from the oil pan to drain the oil.
Allow the oil to completely drain into your oil catch. This may take a few moments. Install your new oil filter while you wait. With the oil drain plug reinstalled, add 15 quarts of fresh motor oil through the oil fill cap, located on the passenger side valve cover.
