[QUOTE="UnleashedBeast, post: 11131253, member: 112023"] Post #1 was updated with a new Motorcraft 5W-50 sample provided by gr8snkbite. Thank you Keith for contributing to the cause, and for paying the extra for TBN. [ATTACH=full]242397[/ATTACH] [B]Wear Metals:[/B] This is typical of a new engine, no warning signs here. Your next sample will improve in this area as the engine breaks in. This is only the second fill of oil in the engine, so no worries here. [B]Silicon:[/B] Since this is only the second fill in this engine, silicon is naturally high. It's the engine lubricant leaching silicon from the sealers used in the assembly process. [B]Viscosity:[/B] The lubricant sheared to a very light 40 grade, almost a heavy 30 grade. This is normal for Motorcraft 5W-50. [B]TBN:[/B] This is showing us that Ford was right to say this is a 7,500 mile lubricant. It may go longer, but they kept the recommendation safe. Under 1.0 is considered low, but you still had active additive left in the lubricant. This is in line with other MC samples in the chart. All is looking normal with your sample, sleep with ease.
