I use Legend ZX-2SR snowmobile 2 stroke oil as both pre-mix and in my dedicated OMP tank. Unfortunately, specs on this oil are hard to find so i am just going off reviews such as the following...

TESTED: Legend ZX-2SR: First off under the microscope this oil is not a synthetic oil, but an ultra pure highly refined mineral oil, the molecules are very small, the pour point was -54f. R.P.M. before brake down of the oil viscosity and film strength is unknown. My test unit only goes to 16,000 R.P.M. and the oil never broke down. This oil is going to be my new oil in my new rush switchback 800, and yes i checked the oil three times in my machines this oil is the best i have tested.

Yeah the flashpoint question intrigues me.
Going off that chart you have some very high performance racing oils at both ends of the flashpoint spectrum. Do you want it to flash cold or hot or burn or not or does it even make a difference at all? As in it will burn with the fuel regardless or not?
Ive used Motul 800(one of the highest performers on ths list) as well as much more generic stuff. There are a lot of people where im from who swear by Stihl oil, which is just rebranded Castrol.
Id love to hear an educated opinion on it.

I did some research on Idametsu premix search, and find out its flashing point is close to Redline 2 stroke

From my Kart exp, the castor oil offer best protection on heat, but it will gum up the carb if u dont drain it after event
I think rotary u want a premix to burn it clean, not fcous on high flash point

I'm going to be working with Schaeffer Oil soon and try out both their 7000 Series TC-W3 and 9000 Series Full Synthetic.

This stuff looks promising and both are good to go with e85.

That's SUPER cheap by comparison. 5x Gallons for $190 as MSRP price.

The Schaeffer's stuff is 5x Gallons for $302.67. Might have to try it out. Wowzers, big price difference!

Per Amazon, the 6 gal pack is only 220 for the synthetic Schaeffer's 9000 series. Haven't been able to find pricing for the 7000 series.
