Can anyone explain the rationale?

If the method of calculation of petrol price is correct, it looks like
we consumers are been screwed all the way. So what are we going to do?
-----------------------------------------------------------------
Petrol price calculation:


1 barrel = 158.987146 liters

Current international price USD54.64/1 barrel
Current exchange rate: USD1 = RM3.61
Previously when oil price was USD145/barrel:
USD145 x 3.3 (exchange rate) / 159 liter = RM3 - RM0.30 (subsidy) = RM2.70

Current oil price @ USD55/barrel:
USD54.64 x 3.6 (current ex rate) / 159liter = RM1.23 (no subsidy)

Current petrol price: rm2.00 but actual price is RM1.23 so we pay back
to government 77 cents. What happen to the money???
