Gas Saving Tips for Nashua Drivers

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.
Fill up before holiday weekends. Memorial Day, Fourth of July, and Labor Day consistently see 10-25 cent price spikes as demand surges. Topping off Thursday before a holiday weekend beats the rush.
