my personal experience as follows. may or may not apply
anyone.
All things being equal (e.g. load, tire pressure, constant RPM bla
bla bla)
95: feels sluggish. consumption went up instead of down. car feels
like it doesn't wanna move.
98: smoother, car feels "lighter". lower consumption than 95.
I drive a Mit Lancer 1.6 Manual, and i do Shell. For some maths, at
the point of writing, 95 is going for $1.423, 98 is going for
$1.493. If you pump 40L,
95 costs $56.92
98 costs $59.72
For a difference of $2.80, I'd go for 98 anytime.
Yes there're some who'd probably say, "yes its $2.80 difference per
tank, but have u considered how many tanks, per week, per month,
per year, per generation ...... until the next Halley's comet how
much you can save?" For that, I have no answer.
