Ultra low sulfer fuel

[D Team Brothers]

Fuel milage is going DOWNNN. Recently we began asking at fuel desks if the fuel was ultra low and the answer is often yes. Now when checking milage we find a major decrease. Additive helps, but what is the future? Any help from anyone on how to boost the MPG while helping not hurting the engine?

Not sure if this was related to the Injector problem I just repaired timming sure seems right.

Hope I am the only one, but watch for Higher Temps, rough idle or white smoke.
