Presently the government officially pegged the price of petrol at
N86.50 per liter, some have argued that its not just possible to have a uniform price of petrol across the entire country owing to many differentiated variable cost due to diverse distribution challenges of conveying products from source to various locations.
Presently Nigeria has about 3 petroleum refineries which are not yet operating at optimal capacity hence the government has to import petrol from overseas to meet up with the shortfall.
From the chart above Lagos state has one of the lowest average purchase price of petrol paid by households, one very important factor responsible for this situation is the presence of a sea port in Lagos through which importation of petrol is facilitated . Also note Lagos does not have any petroleum refinery .
From the charts above there exist price disparity among various geopolitical zones in the country.South west with the lowest average purchase price of petrol paid by households and south east has the highest purchase price paid by households.
In conclusion it very much safe to say that the price of petrol in Nigeria is not at par across the entire states , because some states have certain comparative advantages (closeness to source ) and challenges (high distribution cost).
