I'll admit, I didn't read this entire thread. However, if you REALLY want to know if one oil is "better" than another, it's as simple as doing serial Used Oil Analysis, and having an actual Tribologist interpret the results. Don't trust the clerk that spits out a cheap interpretation, that costs you nothing over the 20.00 or so it takes to have the UOA done...you get what you pay for...nothing of good value. I've read so many clerk comments that shows they simply don't have a clue what they are talking about, you don't know if you got a good clerk or not, unless you know how to do the interpretations.
Here's one common example: a clerk said a particular oil acted like a 10w-40 instead of a 0w-40, but, there was no cold pour point test done. If you do not see the nonsense in that statement, do yourself a favor and pay for a Tribologist interpretation.
This way, you can quit guessing, quit going by, "well, it feels better somehow", and you won't make statements like, "I get better mpg with new oil"...when the fact is: new oil is thicker than used (sheared) oil, unless it has oxidized to the point it begins to thicken...so, you don't get better mpg with new oil because the oil is somehow magically "more slippery" or whatever it is that is being imagined.
I just hate it when oil is treated like religion and/or politics. The FACT is, Tribology is a science that is very well understood by the experts, and we shouldn't have to go by "feelings" and "guesses"...unless, of course, you just don't really want to make the effort to know. And, that's fine...most bikes do just fine on oils that are close to the recommended viscosity, and aren't left in too long. For motorcycles, how long is "too long" is key. Most shared-sump, wet-clutch bikes that I've seen UOA's on are fairly hard on oil by means of shearing fairly quickly.
I've never had a VStrom until this week...so I know nothing about what it's characteristics are regarding oil life. Sorry for the long introduction to this oil thread, but, dag-nab-it, these threads don't have to be unscientific. We have the technology!
