I haven't bought fuel in 4+ months. But I take notice of prices. Here in Thailand it's about 27 baht per L. That converts into roughly $3.35 per gallon. Gas and diesel are pretty closely priced here, unlike the US.

I ride on then back of my girlfriend's motorbike lately, or take a taxi. 60 baht to fill the Honda Scoopy, and it lasts an entire week of frequent use!
