Replacing oxygen sensors can increase fuel mileage, but it's not always the case. Some people have reported an immediate improvement in their gas mileage after replacing their oxygen sensors, but others have found that it made no difference. It's worth noting that oxygen sensors are general wear-and-tear maintenance items and should be replaced as part of a regular maintenance schedule, usually every 80,000 miles or so. While there's no guarantee that replacing oxygen sensors will increase fuel mileage, it's possible that doing so could improve it by up to 15%.
