28. Drive in “Eco” Mode on Long Highway Trips for Better Mileage
Switch to Eco mode (button usually on the center console) for highway cruising. It softens throttle response, optimizes transmission shifts, and adjusts AC for maximum efficiency.
You’ll see an immediate 5–10% fuel saving without sacrificing safety. Real long-distance drivers use it automatically on flat interstates and notice the difference at the next fill-up. It’s like free money at the pump when used consistently.
