pizzaboy, every three tank of RON 92 one tank of platinum might be equal to the price of 4 tank of RON 95.
i think iagree's method (between 92 and 95 only) will be more cost effective.
whattafarck, when the tank is full, i always feel tat the car is more powerful.
I used to pump RON95, when it is full tank, the car feels like going to cheong.
when it is half tank, the car feels a bit sluggish.
i am still wondering why we need 3 tank of 92 to feel the power loss...
could it be that after 3 tank, the tank is all purely RON92?
but even first tank is already majority RON92 and some leftovers of RON95.
can the leftovers be so powerful?
i will monitor my FC.
