A series by The Cincinnati Enquirer analyzed a daily price database of gas prices at 716 stations in the Greater Cincinnati region, including northern Kentucky and southeastern Indiana, to better understand the many aspects of retail gas pricing.

The Enquirer's analysis showed BP had the widest variance with price differences averaging 38 cents between 107 of its stations.
