RE: GAS ENGINES AND HIGH OCTANE FUELS
Bigsport,
Fairly new to petrol (gas) myself. Although I used to run standard unleaded in my Sachs Dolmar 52; I now run BP Ultimate (98 RON) in a DA 100. This was done on the recommendation of the big model flyers up here in sunny Queensland, and I guess if they haven't been having any problems it must be OK.
Just my two cents worth!
Regards
Peter
