fusion all the way.
er actually it's OK to mix different brands of petrol, as long as
they're of the same octane level.
i don't remember the reason liaoz, but it's something about the
speed the fuel burns at. 98 fuel is more efficient because it burns
slower and produces more power than 95 fuel.
so when you mix different grade petrol, it causes the petrol to
burn inconsistently. can feel some slight knocking, bad for
piston.
er....something like that lah. forgot the exact thing liao, lazy to
find also.
