i found out that caltex station fuel quality seemed to be vary severely!!
i pump at 1 caltex station (taman sejati indah sp),
engine become very powerful and good fc...

but another caltex station (taman legenda sp) about 15 mins from the 1st caltex station, their petrol is totally CRAP!!
no power at all when accelerating, need to floor my pedal down to increase speed on the highway while the first caltex just need to press the pedal as light as feather...

so is the 2nd station doing something funny or simply dirty underground fuel reservoir?

i din see that much different in other brand like shell, BHP,Petronas
