A buddy of mine just bought a Ford F350 Super Duty with the 6.2L, this is the gas engine.
The owners manual says 5W20 Motorcraft Synthetic Blend, 7500 miles, severe use 5000 miles, he just can't grasp the use of 5W20 for this heavy duty truck and the interval. Heck, he just can't grasp 5W20 at all!
Just goes to show how good the 20 weight must be, and the Motorcraft SynBlend, Ford is confident.
