Diesel prices in South Carolina reached a record $6.15 per gallon. This marks a year-over-year increase of nearly $2.69.

Diesel prices in South Carolina hit a record high of $6.15 per gallon. This figure represents a year-over-year increase of nearly $2.69. According to GN auto markets/energy: gasoline prices, regular unleaded gasoline averages $4.11 per gallon in the state. This price sits 49 cents below the all-time high of $4.60 set in June 2022.

The state’s average regular gasoline price is 32 cents lower than the national average of $4.46. In the past 24 hours, the national average for regular gasoline rose by seven cents. Consumers report that current price levels significantly impact their daily driving habits and budgeting.

Legislators Debate Tax Suspension

South Carolina’s gas tax stands at approximately 29 cents per gallon. This rate ranks 20th lowest among U.S. states. Congressman Russell Fry has called for a suspension of federal fuel taxes. Attorney General Alan Wilson proposes granting the governor authority to suspend state gas taxes for 120 days.

Governor Henry McMaster opposes reducing tax revenue for road maintenance. He argues that infrastructure funding is a long-term necessity. The state currently uses these funds to keep roads fully maintained. Lawmakers are divided on whether temporary relief outweighs the risk to public works budgets.

Global Conflict Drives Prices

Brown University data links price spikes to the U.S. entry into the war in Iran. Since February, regular gasoline prices have increased by 49 percent. Diesel prices have risen by 74 percent over the same period. These trends coincide with broader geopolitical tensions affecting energy supply chains.

The rapid price increase has outpaced typical seasonal adjustments. Analysts note that supply disruptions are the primary driver. The current market environment remains volatile. Consumers continue to monitor daily fluctuations in pump prices.

Consumer Impact on Spending

Local drivers report limiting vehicle use to save money. One resident with a car lot now conducts two-minute test drives. Another resident stated that any price below $4.00 would provide necessary relief. These behavioral changes reflect the immediate pressure of high fuel costs.

The economic strain is evident in local business operations. Reduced driving frequency is a direct response to high costs. The situation highlights the sensitivity of households to energy price shifts. The market remains focused on potential regulatory interventions.
