2011-2014 Ford 6.7L Powerstroke Engine Oil

Engine oil for the 2011-2014 Ford 6.7L Powerstroke

The 6.7L Powerstroke holds 13.0 quarts with the filter. That's a little over three gallons, so a full change takes four of the 1-gallon jugs on this page with a few quarts left over for top-offs. Ford's preferred grade is 10W-30, with 5W-40, 15W-40 and 0W-40 listed as alternatives, and synthetic is recommended. The interval is 10,000 miles in normal service and 5,000 in severe service.

What goes wrong with oil on this engine

Two things show up on these trucks. The first is fuel dilution: post-injection during active DPF regeneration puts fuel in the oil, and short trips and long idling make it worse. A rising dipstick or a diesel smell is the sign; more highway driving and less idling cut it down. The second is a clogged CCV oil separator, which raises crankcase pressure, pushes oil past healthy seals and shows up as higher oil consumption and oily charge pipes. Diesel Hub recommends replacing the separator every 30,000 to 40,000 miles.

Choosing an oil

The grades here that match Ford's list include Hot Shot's Secret Green Diamond, Blue Diamond PAO and Black Diamond Outlaw 10W-30, Lucas Synthetic Blend 10W-30 CK-4, Hot Shot's Secret Green Diamond and Blue Diamond 5W-40, and 15W-40 oils from both brands. The page also carries Hot Shot's ADRENALINE R-Series racing oils in 5W-20, 10W-30, 15W-40 and 20W-50, and a Green Diamond 0W-20 light-duty diesel oil. 0W-20, 5W-20 and 20W-50 aren't on Ford's list for the 6.7L, so if you're filling this engine, stay with the listed grades. Whatever you buy, read the API category and approvals printed on the jug and compare them to Ford's CJ-4 and WSS-M2C171-F1 spec.

Fitment notes

Oil fits by spec, not by part number. Match the grade to Ford's list, match the API category and Ford approval on the jug to CJ-4 and WSS-M2C171-F1, and buy enough for 13.0 quarts. If you're on the 5,000-mile severe schedule, you'll be buying twice as often as a truck on the 10,000-mile schedule.
