Keeping your oxygen sensors fresh may improve fuel economy as much as 10%-15%. The oxygen sensor should be considered part of a tune-up on todays vehicles. Keeping the sensor in good operating condition will also minimize exhaust emissions, reduce the risk of costly damage to the catalytic converter and ensure peak engine performance (no surging or hesitating).
Fuel injection systems require cleaning at regular intervals, every 35 – 40 thousand miles. This process is necessary because varnish deposits, dirt, and carbon build up on the end of the injector nozzles, inside fuel rails, inside intake plenums, on the tops of the pistons, and inside the cylinder heads and valves. A professional cleaning of the injection system and upper regions of the engine usually results in increased performance and better fuel mileage. We recommend that you visit a professional service technician for more information.
