problem 1:
mine experience probably is different, at first i thought my car had issues, then came the idea maybe its the prices which shoot up almost daily, i fuel at one particular station. along msa road i think at round 97.6 per liter, with 1500/= i would do my week's errands then will fuel on saturday for my weekends errands. of late by wednesday the red light comes on I got to refuel, which calx that same errands at an extra 500 bob a week.
problem 2:
the starts to lose power esp when im doing over 100km/h, I realise my collegues too, have this problem, i go to my mech and im told "unatumia mafuta chafu...." he tell we have to be changing the fuel filter when doing the car's service.
