yup, thats the same issue that i am having..having read and understood the fact that 'unless the car demands a better fuel' don't pay for a premium fuel, unnecessarily sooner i will be switching to a car having VVT-i (toyota) so, i need to decide on it now it self, as to which i am gonna pump from the start, as it has never been used in SL yet..
also, if the prices go up again, first they had a difference of 3, now its 13, and next who knows how much the difference will be? and having to pay the premium charge, unless having a worth-while point, bothers me a lot,
yeh, no one pays for my fuel, and unfortunately what i earn for now is no big deal, and can be packed in the pocket at once
