important is USE 5w20 full synthetic with motorcraft oil filter.


if you don't use right oil weight you destroy 5.4L. They have tight bearing clearance.


They are pretty damn tough engine I have use before. I know 1 guy who abusive his 01 F250 xlt lariat by plow snow plus 55 mph in reverse

hit 6,500 rpm often. didn't change oil 30,000 miles overdue. Now I maintain his truck for now.

Clean throttle body with old toothbrush you be surprise how carbon fill on it.

Change spark plug at 50,000 to 60,000 miles and follow their direction how to change spark plug if you don't follow you end strip thread in head for spark plug.
