[QUOTE="UnleashedBeast, post: 11806331, member: 112023"] Haven't we already concluded that engineers can be overridden by upper management? It's been documented. A true synthetic 10W-40 is the way to roll when Motorcraft 5W-50 is called for. However, if you wait for it....they will say I'm crazy and not a Ford engineer, that I don't know anything. Meanwhile, they ignore the true facts about Motorcraft 5W-50 1. Shears rapidly to a light 40 grade lubricant 2. Cheap hydrocracked base stock provides greater friction than a true PAO/Ester 3. Engine performance and efficiency suffers greatly with MC 5W-50 What's the relevance is this? I've provided solid proof the GT500 engine ($15,000+ dollar replacement) is solid on Amsoil AMO 10W-40, no 5W-50 required. Yet the GT guys with a 5.0 ($6,500 dollar replacement) argue with me about it. Epicness! Reasons 1. Lightest material that's feasible for a driveshaft, less parasitic losses (lower rotational mass), more go fast for the 2013 GT500 2. Best resonance resistance, better than steel or aluminum 3. The older steel two piece is not as suitable for the torque created by the factory engine. The Carbon replacement is stronger 4. Dual CV joints eliminate any additional chance of vibrations up to the rated top mph. The steel two piece shaft would have never survived it. What's so funny about it? I obviously know why it was done, and why the aftermarket offers versions of it for any S197. [/QUOTE]
