Where the $3.72 goes

Component$/gallonShareSource
Crude oil (national cost, WTI June 2026) 2.02 54% EIA
Federal + North Carolina fuel taxes (18.4¢ + 40.5¢) 0.59 16% Tax Foundation
Refining, distribution, margins & embedded program costs (residual) 1.11 30% computed

Crude oil costs every state's refiners roughly the same, so North Carolina's position comes from the tax line and the residual: refining capacity and logistics, fuel-specification requirements, and any carbon or clean-fuel program costs embedded in the pump price.
