if you ppl say no difference between 92, 95, 98 or v power....
then why do they come up with these in the first place? besides,
different ppl are driving different cars choosing different
stations to fill up... but come to think of it, using a high grade
fuel once in a while does has it's benefits, logically speaking.
same principal as changing your engine oil during servicing...
after the oil change you feel that your car can rev better....
change transmission fluid you'll find you can shift easier and
changing brake fluid, better braking yadiyadiya....
