I have two RCV-engines, a 90SP and a 91CD, and I wonder if I can use the new fuel from Model Technics. The instructions recommends using Duraglo 10, but my LHS says Duraglo 10 is no longer in production and has been substituted with a fuel called ProPower 10. As far as we can see this fuel contains 18% what we believe is fully synthetic oil with an additive they call "Sical". The label says: "18% EDL2 with Sical".
As I know there has been some issues regarding castor or no castor, especially on the SP-series, I just wonder if I can use this fuel, or any other no-castor fuel for that matter, on my engines?
