[quote]Plain and simple, have used Rotello oil in diesel engines for years and have no problem changing oil in my recently acquired Roadstar. I don't mind spending the money for Mobil 1 or Amzoil or Royal Purple or whatever, especially since my local dealer wants $100 for a semi-synthetic Yamalube oil change. However, I have access to gallons of Rotello T 5W-40 synthetic($15 per gallon). I know some folks on this board use it and just want some "testimonials" about it's performance. I ride in temperatures from 35 to 100.

My Roadie loves it (as did my Concours & Shadow), I get less valve noise & clean-looking oil coming out @ changes. It's cheaper than any other synthetic out there & can be had at any Wal-Mart, AutoZone or truckstop on the road. My riding temps are similar to yours (20 in winter to 105 in summer) & I ride mine hard!
