On April 5, 2026, fuel prices across the United States have seen a slight increase, with the national average for a gallon of regular gasoline rising to $4.110, up from $4.104 the previous day. This increase is primarily driven by a surge in global crude oil prices due to geopolitical tensions linked to the ongoing conflict in Iran, which has disrupted supply chains and unsettled energy markets. In California, the price of regular fuel is notably high at $5.923 per gallon, while Texas reports a significantly lower price of $3.824. Other states like Florida, New York, and Pennsylvania exhibit prices in between, reflecting regional disparities influenced by local taxes and refining capacities. Analysts warn that consumers should brace for continued elevated gasoline costs as relief may take time to materialize.
