Gas Saving Tips for Johnson City Drivers

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.
Download the Upside app for cashback on gas purchases — users report average savings of 20-30 cents per gallon on qualifying transactions.
