The Army and Air Force Exchange Service has implemented a new overseas gas price policy to help minimize annual price fluctuations. Under the new policy, the sell prices for gasoline and diesel fuel are established by grade, based on the Department of Energy averages from the previous month, plus each region's incremental dispensing costs.
Gasoline is priced in the world market daily.
As such, having a yearlong price is antiquated and simply not realistic. This is the reason for the big fluctuations seen in the past, such as 42 cents last year. The new policy will minimize that effect. The price and frequency of change varied between the regions, usually depending on local situations. This price was fixed based on the market price at that time and not adjusted as prices dropped or raised in the stateside market.
