I haven't seen an oil thread in a while. In an effort to stir the pot here I go.
I was at Walmart today and I decided to check out the Mobil 1 selection.
Exhibit A:

5 quarts of automotive grade 15W-50. It says it has extra zinc which is more important for older engines. $22
Exhibit B:

1 qt of Mobil 1 4 stroke "racing" oil. $10
Exhibit C:

1 qt of Mobil 1 V-twin oil. Good if your oil is shared with the clutch and tranny. Neither apply with the V11. $10
Considering the auto oil is a fraction the cost of the motorcycle oil it's tempting. Fully synthetic, added zinc and about the right weight.
Most of you are too old to know what a /r/roast me is but I'm ready for your worst. Go!
