[QUOTE="UnleashedBeast, post: 11378254, member: 112023"] A new UOA sample from a 2012 GT500 was sent to me today. It's the factory fill with only 1,000 miles of use. This is about the right time to dump the factory fill, as you can see wear metals are on the rise from the initial break in period. [ATTACH=full]271077[/ATTACH] The report looks very normal, but one spec overall shocked me. This is the first time I have seen oxidation this low on a sample of Motorcraft, or any lubricant tested from a GT500 for that matter....yet it's still flagged. Come on OAI...how do we satisfy thee? :smmon: I ignore this spec on all samples from OAI as it's become a wonder how they ever come up with it considering a virgin sample of the oil being tested is required to calibrate the machine for testing (so I'm told). Again, viscosity has sheared to a 40 grade lubricant, no surprise here....that was expected. This time at only 1,000 miles of use. Why I know a 50 grade lubricant is over kill for this engine.
