Why Diesel Costs $5.08/Gal in Ohio
Ohio sits at the crossroads of I-70, I-71, I-75, I-76, and I-90 - more major interstate intersections than any state except Texas. This makes Ohio a major fuel stop for OTR drivers traversing the Midwest. Ohio's state diesel tax of 47 cents/gal is high - partly due to Ohio's major road maintenance needs from heavy winter truck traffic. Columbus and Cleveland are major fuel distribution hubs. Ohio's proximity to Midwest refineries (Wood River IL, Lima OH) keeps pre-tax prices competitive.
