One can aslo pour one bottle of Red Line Fuel System cleaner every 4 fillups, and this will keep the lines clean, as well as the injectors clean, and this will keep the engine running smoothly, which in turn saves fuel, plus lets you take advantage of the engines HP more. Mix that with the K&N and a well working exhaust system and you should be lookin at improved mileage. I have a 96 D1 Auto by the way. And I have CERTAINLY noticed the difference. Last weekend I went up to West Palm Beach from Miami ( about 80-100 miles away from where I am ) and I consumed 1/4th of the full tank
