Its subsidized by the government here. As of now its like 11 to 12 baht a liter. So my wife fills up for 500 baht. I am on petrol and 49 liters here cost me 2000 now. I get 470 kilometers on that as it is all city and soi driving, very little open road. The wife gets like I said about 420 on lpg. But she is highway and town both.

so the bottom line is she fills up in a 2.0 liter engine every 420 K, it costs her 500 baht. I fill up every 470 and pay 2000 baht on a 1.6 manual, that does get 16 K per liter on the highway at 110.
