Frequently Asked Questions

Gas price trends in South Carolina follow national crude oil market movements combined with regional refinery and supply factors. Seasonal patterns typically see prices rise in spring (summer blend transition) and ease in fall and winter.
Four main factors drive South Carolina gas prices: crude oil cost (50-60% of the price), state and federal fuel taxes (28 cents + 18.4 cents federal), refining and distribution costs, and retail station margins. Crude oil price swings cause the most dramatic short-term changes.
Use GasBuddy, Waze, or Google Maps to find the cheapest stations near your location in South Carolina. These apps aggregate real-time price reports from users. Warehouse clubs (Costco, Sam's Club) require membership but consistently offer 10-25 cents below street prices.
Some states offer low-income energy assistance programs that help with fuel costs. Check with South Carolina's Department of Social Services or energy assistance office for current programs. Federal LIHEAP may also provide indirect relief.
Gas stations in South Carolina typically update prices once per day, usually in the morning. The key is the day of the week — Monday and Tuesday before mid-morning updates typically reflect the weekly low price.
