Even if there was a fuel additive to improve gas milage it wouldn't be cost aefective. The additive would probably run you $5 or more and you would have to add it all the time therefore not really saving you anything. All the mods in the world aren't going to make a big difference in MPGs. You might be able to squeeze 1 or 3 more MPGs at best with better intake/exhaust/programer etc., but all that will cost you. It is what it is and the only way to effectively improve your milage is drastically change your driving habbits to "Granny Mode" or find a way to reduce the weight of the truck by 1000 pounds...lol. If there was a way to significantly improve MPGs I'm sure it would come with that mod from the factory and set the truck far above the current standards that these trucks are getting.
