For those thinking/considering of converting to Auto-LPG.

How much is your fuel bill?

P37.00/L unleaded gasoline
P18.90/L Auto-LPG

50 liters of fuel:
gasoline = P1,850
auto-lpg = P945

Assuming you refuel 4 times a month:
gasoline = P7,400 / month
auto-lpg = P3,780 / month

Monthly fuel cost difference = P3620.00

So if you convert to Auto-LPG, you save P3620 per month which is computed to P43,440 per year.

Not convinced? Check the news on the prices of oil... it's trend will be to increase as colder weather moves in.
