eh Ron97 or 95?
if you rm10 go 40km, means rm50 go 200km... that's kinda bad lei

IIRC if i pump rm50 ron97 i get around 250km, if ron97 (rm50 also) i can hit 280km....again all 100% city driving lo.
will exhaust leak (small bocor) cause FC increase? or power loss? my low-end torque seems to be poorer than i remembered

if i send to exhaust shop, i just afraid they simply say here n there need replace

thats why must ask u all for tips and advise first.
I always wonder how rm50 ron 95 @1.90 = 26.3L = 250km
= 9.6 km/L
and rm50 ron 97 @2.50 (let's say take a lower one) = 20L = 280km
= 14 km/L
That is a big variance. Can you maintain that stats for 3-5 full continuous tankfuls ?
Is there something in ron 97 / V-power or is the full tank-ful method to calculate is not that accurate ?
I use my km/L for full-tank full, there is not much difference, only +/- 20km
Exhaust pipe leak = FC will increase. Loss power also. Also your exhaust will sound like
ah beng modified exhaust, very loud

at traffic light, you step 9 9, engine rev high, exhaust sound nice, but the kancil/lorry next to you pickup faster than you
