I don't know how many times this needs to be repeated before people stop speculating otherwise...
Thanks for that info.
Another interesting point. Is this engine is designed for E10 or did they decide it should be alright from the spec? My car states on the filler cap 98 RON only. On my mates 2013 Ford Fiesta is says 91RON or higher and E20 compatible[something like that]. So why isn't the FA20 suitable for any ethanol in Oz but it is in the US?
