Tennessee expert shares tips to save on gas

A gas expert from Tennessee has shared tips on how to save money while filling up, helping drivers avoid being overcharged. In a viral TikTok video, John Brown explained four tricks to get more fuel for your dollar. His video has gained over 203,000 views and has sparked interest among many viewers. Currently, the average gas price in the U.S. is $3.102 per gallon. However, prices remain high in states like California and Washington, where it can exceed $4. Brown's tips are aimed at helping customers save money at the pump. One tip is to fill up in the morning. Brown advises that gas is denser when it's cooler, so filling up when temperatures are lower can give you more fuel. He also suggests filling the tank slowly. Pumping gas too quickly can turn some of it into vapor, which you won't receive. Brown recommends using the lowest speed on the gas pump to ensure you get the full amount. Another tip is to refuel before the tank is empty. Brown warns that gas evaporates when exposed to air, so waiting too long can lead to losing fuel. Experts generally agree that refueling when you have about a quarter tank left is best. Lastly, Brown cautions against filling up when a gas truck is delivering fuel. This can stir up dirt and debris in the tanks, potentially contaminating your fuel. While not scientifically proven, it's a precaution many experts recommend.
