The given table illustrates the ten most expensive countries for petrol with other financial information. Overall, the average monthly petrol expenditures among countries are within a relatively small range. Hence, countries with higher average monthly disposable incomes have lower percentages of monthly income on petrol.
To begin with, the Norwegians and the Turks stand out as they spend the most money each month buying petrol, recording $319.85 and $315.96, respectively. Meanwhile, the figures are similar for citizens from the remaining countries. They need around $280 every month to refill their oil tanks. People in Belgium only spend $273.05 monthly on petrol.
In the meantime, the most developed countries spent the lowest percentage of monthly income on petrol. Nordic countries, such as Norway, Sweden, and Denmark, are among the highest-earning countries. The Norwegians earned an average monthly disposable salary of $4329.07, and they only spend 7.4% of it on fuel. Swedish and Danish people roughly spend 8% of their usable wage. On the other hand, people of Eritrea merely earn around $450 of disposable income. They have to finance more than three-fifths of it to keep their cars running.
Overall, while there is little gap between the monthly petrol expenditure among countries, the difference in the percentages of monthly income spent on petrol is huge.
