Hi Dirk, I'm a previous Jetcat and current Wren owner/operator, been flying turbines for about eight years now. I really like what I see with the Kingtech stuff. Thank you for the reply!

PS, I still have what's left of a case of "Mobile Jet Oil II", probably 8 cans left and I've used this with my Jetcat and Wren engines with no issues what so ever. Are you aware of any sort of incompatibility with this brand and the KingTech engines? Specifically I'd probably be looking at the 140K. In the future I'd prefer to move forward with the newer synthetic 2 stroke oils you guys sell and recommend for toxicity (or lack there of) compared with turbine oil.
