Summer is comming so maybe some of will spend their holidays in Dubai. Don't hesitate to rent a car there. While browsing internet as usually I came across receipt containing gasoline price from gas station in there:
As you can see 27l (like 7,3 gallons) of gasoline costed 50AED which is around 13,5USD. From what I did read it happens that it still isn't cheapest gasoline price in the neibourhood as Dubai doesn't have its own oil reserves. To give you wieder point of view the same amount of gasoline in the states would cost you around 26,3USD.
When looking at prices like these I regret living in middle Europe where for 27l of fuel I would have to pay equivalent of 55USD; in my country where currencys purchase power is way lower.
