well it been a while now that we have used the coptermix 20%.we have used about 6 gallons now. As we dont fly every week and when we do we have no problems at all with the starting up of the 55 in the 600.I have just taken the back plate off to check the bearings. no damage visiable or rust which has surprised me as we must leave fuel in the engine after each days flying and all week.Im very happy with this fuel will update after we put more threw it.
thanks
thanks
