then at the later stage ...... i started to utilise all CNG first , until empty , run on petrol later until finished work . COs CNG price and petrol , very close that time .
Eh , i made the same amount of money leh .
Even more sometimes , although i spent $10 on petrol daily .
I was a happy man , cos on the 10th of each month , i got about $500+ into my account automatically .
$500 every month , i can afford to use petrol lah .... no sweat .
