I finally got around to sending in the sample of Mobil 1 20w-50 V-Twin. Here are the results.
Mobil 1 20w-50 V-Twin
Blackstone Labs
Sample Date: 03/11/04
"Nothing too unusual showed up in this virgin Mobil oil sample. Note the slight presence of sodium, which will also be in your oil samples, should you choose to use this oil in your engines. The viscosity is just a little higher than our standard range for 20w/50 oil, but it's still okay. The TBN read 10.8."
