Running Mobile 1 15-50 in our Spyder SE5 RS and it runs cooler and shifts smoother.

I was looking at the Mobil 1 site and did not see a 15W-50 motorcycle oil?

Only saw this at Mobil 1 Motorcycle Oils:

"... Excellent transmission performance (in 10W-40/20W-50 grades)..."



Did I miss something?

Thanks in advance.
