Gas prices in Hilton Head Island, SC

About gas prices in Hilton Head Island, SC

South Carolina sits on the Colonial Pipeline mainline, which supplies most of the state's gasoline from Gulf Coast refineries en route to the Northeast. The state gas tax is around 28 cents per gallon. Charleston, Columbia, Greenville, and Myrtle Beach all see relatively competitive pricing, with the coastal cities sometimes benefiting from direct tanker shipments through the Port of Charleston. Costco, Sam's Club, Murphy USA at Walmart, Sheetz (with strong Upstate presence), and Wawa (entering the market) lead on value. Hurricane season can disrupt Colonial Pipeline operations and cause statewide price spikes, particularly when storms shut down Houston-area refineries that feed the pipeline.
