Gas Saving Tips for Charleston Drivers

Use a gas rewards credit card. The Costco Citi Visa earns 4% back on eligible gas; Blue Cash Preferred earns 3% at US gas stations. Pairing a reward card with a warehouse club maximizes savings.
Avoid filling up at highway exits, airports, and tourist areas where convenience premiums routinely add 15-25 cents per gallon.
Keep your tires properly inflated to the manufacturer's recommended PSI — under-inflated tires reduce fuel economy by up to 3%, costing you money every mile.
Accelerate and brake gradually. Aggressive driving can reduce fuel economy by 15-40%, directly increasing how often you fill up.
Track weekly price cycles in your city — most markets follow predictable weekly patterns. Identifying yours and filling on low-price days saves 5-15 cents per gallon consistently.
