Some have posted what might happen in the future - that diesel might overtake gas, that diesel tech will still improve, etc etc. But that is the future. These predictions might not actually happen, and to some extent, I don't believe them, or I don't believe them enough to affect my decisions or plans for today. Today, in the Philippines, the most expensive is gas. You can only save a few pesos with diesel. But you can save the most in lpg TODAY and NOW. So in reality, as of today, in the Philippines (Australia, etc), mas maganda na car engine gas running on LPG.
