Mogas, huh
It stinks -not as much as the old super used to - it's dirty, in northern OZ it's more expensive than avgas, it dissolves the lining sealants on some A/C types which then clog your filter, it melts o rings and gaskets used on some A/C carbies.
Notwithstanding that when super was much cheaper way back when, we used to use it sometimes, to use it regularly you must have first bought an "STC'd mogas kit" that is designed to circumvent the above.
apart from that it is now illegal in north OZ to carry mogas into many aboriginal communities as the naughty little juveniles thieve it and use it to satisfy their petrol sniffing habit, which would leave you short of fuel to fly home - a real bummer - while you contemplate your misdemeanour in the local slammer with the local outcasts.
There has been a new type of petrol designed to circumvent this sniffing, called Opel fuel. don't tell anyone but some of the more inventive little juveniles have bin-a mixin-it with chips of polystyrene and proceeding on their elevated way.
For an extra couple of dollars an hour op cost why bother.
