About naman po sa fuel pag dating sa gasoline, kahit anong brand pa yan at pag haluin ang octane rating, no problem po yan, sa long as po na "Gasoline", wag lang "Diesel" [/QUOTE]

all current gasoline fuels are mix-able with each other, with no ill-effects.
just be sure your engine's octane requirement is met.
same with diesel fuels.
