[QUOTE="UnleashedBeast, post: 11923799, member: 112023"] I've heard about that guy, where can I find him? :lol1: Motorcraft (unsheared) is too viscous in the summer for a street car. Oil pressure is too high. MC 5W-50 rapidly shears to a light 40 grade lubricant in about 2,000 miles. That's why we adopted a true synthetic 40 grade lubricant in the GT500 community that wouldn't shear and hold the viscosity. Unless you are road racing the new GT for extended sessions, the 5W-50 recommendation is OVERKILL! The engine would function fine with a lubricant as light as a 5W-20 for grocery getting grandma driving. I'd be more prone to use a true synthetic 30 grade lubricant for street duties, aggressive street driving, and drag racing. Use a true synthetic 40 grade for road racing.
