Want the extra protection of castor oil that you're not getting in Cool Power but like how Cool Power runs and want to stay with Morgan fuels?

Omega is basically Cool Power with some percentage of the synthetic replaced with castor.

It's worked good for me ever since I got back into the hobby. I sold an engine that had one year's worth of flights to a buddy who promptly crashed it. When he continued the disassembly to salvage some parts to rebuild one of his he discovered his had rust and mine was shiny and bright. He switched to Omega then and there.
