[QUOTE="UnleashedBeast, post: 14204794, member: 112023"] You really think your RoadRunner is something special because it can turn a few hundres RPM more than a Coyote, and about 1K more than a GT500? Please tell me how you are holding your car above 7,000 RPM every second of your track driving. Engine lubricants can easily achieve 300*F around the pistons on the road course. That's where the HT/HS (high temp/high shear) specification comes into play. How many times do I have to repeat myself. Motorcraft 5W-50 shears rapidly (good bye HT/HS virgin specs). Unless you are changing your oil at every track session, you do not have a 50 grade lubricant in your engine. If you want a dedicated lubricant for road course racing, stop messing with inferior 50 grade lubricants. Use this, it will not shear like Motorcraft.
