Where the $3.31 goes

Component$/gallonShareSource
Crude oil (national cost, WTI June 2026) 2.04 62% EIA
Federal + Texas fuel taxes (18.4¢ + 20.0¢) 0.38 12% Tax Foundation
Refining, distribution, margins & embedded program costs (residual) 0.89 27% computed

Crude oil costs every state's refiners roughly the same, so Texas'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.
