[QUOTE="UnleashedBeast, post: 11071860, member: 112023"] Excellent idea. Run it for 2,000 miles, take a sample, then verify what I have been saying about a true synthetic 10W-40 being more efficient than any 5W-50. Amsoil's legal department will only allow them to recommend the oil they formulate that is suggested by the manufacturer. Since Amsoil refuses to formulate a 5W-50 due to very low demand, they do not have an oil recommendation for the Shelby. Even though their true synthetic 20W-50 has very close to the same viscosity as un-sheared Motorcraft 5W-50....they still don't. Royal Purple doesn't have that restraint....as they openly recommend 10W-40 from their line up. Imagine that! [/QUOTE]
