here we go,
I called them and I was recommended to use the oil in the link below, "Mystik® JT-4®Ultimate High Performance 2-Cycle Engine Oil"
I was told it's a clean oil that will actual clean a dirty engine over time (test have proven)
it's the latest technology in oils, it has been used and tested in all types of 2st engines including Chainsaws, Scooters and Dirtbikes and Boats

he did not recommend this oil for Model Heli engines or other engines turning 12,000/ 13,000 because an engine turning that high should use a thinner oil because of the Ball and Race clearance in the Bearings
BTW if this helps, (in short) I told him about a well known 2st oil that is known to run hotter than other oils, I was told> " then you are getting more friction"
hope I have helped
