Follow This 'Half-Tank' Strategy To Save Money on Gas, According to Clark Howard
Gas prices go up and down all the time, but more wildly than ever these days. It's time to take back a measure of control.
The national average price of gasoline was $4.44 at the end of September 2026, according to GasBuddy. While prices can vary widely by state, there could also be a 50-cent or more difference between the cheapest and most expensive gas station near you, according to consumer advocate Clark Howard.

Instead of waiting until your vehicle is almost empty to fill up, try Howard's “half-tank” strategy, and startshopping for the best price when you’re at half a tank of gas. Here’s why.
Monitor Gas Prices During Your Regular Commute
When you hit half a tank of gas, start paying attention to gas station signs on your regular commute, Howard said. Also, take note of which stations consistently have lower prices than others.
This will give you more time to compare options instead of pulling into the first gas station you see. And when you notice a few stations that regularly offer better prices, you’ll know where to stop the next time your tank is at the halfway point.
Look for Stations That Haven’t Raised Prices Yet
Ross Enterprises, a fuel wholesaler, said that neighboring stations can have different costs because they’re selling different inventory. One station may still be selling fuel delivered before a wholesale price increase, while another station may have received a newer, more expensive shipment.
According to the American Petroleum Institute (API), most gas stations in the U.S. are independently owned. Prices at individual stations are influenced by various factors, including the cost or anticipated cost of the next fuel delivery.
Local competition can also influence prices. Stations watch each other’s prices, Ross Enterprises said, and if one drops its price, then others typically follow. If the price goes up at one, others may hold for a day or two until they’re forced to increase prices as well.
This is more common during periods of volatility. If you see a price that is much lower than what you’ve seen recently, Howard recommends filling up right then and there.
Compare Prices Before You Fill Up
Howard said that he recently looked at several metro areas and found as much as a $1.75-per-gallon difference within just a 5-mile radius. For a driver filling up a 15-gallon tank, choosing the cheaper station could save about $26 on a single fill-up.
You can also use tools like GasBuddy and Upside to compare prices and save money on gas. GasBuddy helps drivers find the cheapest local gas prices, track fuel savings and earn rewards, while Upside gives cash back on gas, groceries and dining.
Some retailers like Walmart or Costco often use gasoline as a marketing tool, according to Howard. They may delay raising prices to get your business. CNN reported that Costco beats gas stations by a typical 30 cents per gallon while still making a profit.
