The first post was just updated with the new sample provided by my little uranium friend. Some have said that he lights up like a glow stick in the dark, and never requires a flashlight to see. We know him as NuclearPower!
Thanks for sample #2. Your samples are now numbered #15 and #16 on the chart, and I used Smurf Blue as your highlighted color. Now isn't that Smurfy! Yes, I noticed they are not in order...I'll fix that next time.
Your wear numbers look fantastic for a 5,000 mile interval with an engine less than 10,000 miles of use. Now that the samples are side by side on the excel sheet, you can easily see the decline of wear metals and silicon. Silicon is from the sealers used to build the engine, and will decrease even further next sample. Ignore the comments to "check your air induction system". Depending on the tech that runs your sample, not all of them know this is normal in the GT500 engine. Some do though. I know the message from the tech seems scary, but ignore it. TBN isn't lower than it should be, oxidation should be ignored, we already know why silicon is so high, and we are already aware that Motorcraft shears.
The lubricant sheared ~30% to a light 40 grade lubricant @ 13.9 cSt. Your new fill of Amsoil 10W-40 will maintain a 14.5ish viscosity range and shear very little (less than 3%).
TBN is right on par for a 4900 mile interval. No worries there. You still had plenty of active additive remaining up to the 7500 mile recommended interval from Ford. I know the lubricant can do it, and every UOA I see around the 5000 mile interval confirms this. TBN isn't depleted in a linear fashion, but this sample is on par with all of the others.
Everything looks great, and I will be the first to admit....Motorcraft 5W-50 is doing a far better job in the newer aluminum engines than it ever did in the iron block variants from 2007-2010. Can't wait to see your next interval from Amsoil 10W-40. Thanks again for the contribution to the GT500 community here at SVT Performance.
