My oil change experience was just like yours. I even reused the crush washer because it was not at all "crushed". Very watery. But I used 10-30 again anyway.
I wonder sometimes if the "thick oil" preference is just a visceral thing. The oil is supposed to lubricate and mitigate friction. Thick oil might "feel" like it's holding more of a space between surfaces. Thinner oil might get into tighter spots that a "thick" oil can.
So who knows. At some point I may return to the 5W-40 Rotella T6. Dunno.
Probably the best oil you can use is "fresh."
Going to change the oil in my CB with Rotella T6 this week. The factory service manual okays the use of a "10W-40" when the bike is used in an area with high average temps. I used Rotella in all my other bikes for years and never had a problem. The Honda branded oil is made by Conoco-Phillips as is Ford's Motorcraft oils. And Rotella T6 is a bargain at Wal-Mart. Curiously, I cannot find any reference to a motorcycle specific oil on the Conoco-phillips website.
