thanks for help and disscussion so far. the manual for my cors air M 25 Y black devil describes the fuel in a number of ways as:
premium petrol 98 octane
97 octane gasoline
4 star (super) fuel
my question is this;
is this just American for normal unleaded petrol
their are two choices at my petrol station unleaded and super unleaded
which should i choose? Also, if either is ok, is there an advantage for using the more expensive super unleaded and what would that be?
thanks for help
Andy
