Where does he say this? The only mention he makes on difference between M1 15-50 and the V-twin oil is:
"One, but the consensus appears to be that the new SuperSyn has additional friction modifiers and may no longer be a good choice for motorcycles. However, I have heard from several VFR owners still using it with favorable results. Therefore, YMMV. Mobil naturally recommends their motorcycle Mobil One."
That hardly supports your claims.
I also could find no mention of STP. None. Nadda.
What he
does say is:
"A number of motorcyclists have reported to me good results so far with his use of the new Synthetic Rotella-T. I put it in my own VFR at my last oil change. "
He also says:
"My favorite oils and the ones I most mostly recommend for motorcycle use, are the "heavy-duty" oils. They are commonly misunderstood, and often referred to as 'diesel oils.'"
"6. Shell Rotella-T 15w40 (my personal favorite)"
So, we can conclude that Mike used to use Shell Rotella-T 15W40 conventional oil, and recently made the switch to try out Shell Rotella-T synthetic 5W-40 oil. Unless you have a private e-mail from him that says he's using M1, I can only conclude that you didn't read the report you sited.
I think you're confusing this web site with the study posted on the BMWOA web site. That study is old, comparing the old Tri-synthetic formula M1 15W50 oil with the 20W50 Motorcycle oil. M1 has gone to a new formulation it calls SuperSyn(thetic), and you really can't compare the new oil to the old oil. That article was 5-7 years old, which is a long time in the oil world. The conclusions are not valid anymore to current off-the-shelf oils.
I smell an alterior motive...
