The last week I have been wondering what is happening to my mileage? I have only got 255 miles on 19.232 gal. and 249 miles on 19.891 gal. My truck normally gets 350 miles out of a tank. Is there something I'm missing? I thought all new vehicles had anti-siphon devices?

Biodeisel blend? may impact that, or did you get some no 1 by accident? if it continue get your air ti air pressure tested. also the obvious is the fuel and air filters but im sure you checked that. or hot fuel-check the nozzle when filling-is it warm to the touch-that could be an issue as well. sounds like a combination problem maybe+
Wow thats weird. It could be the fuel changing back in to the summer stuff.
On another thought maybe the winter stuff hasnt converged yet. I wonder if the heat in florida would cause the winter fuel to burn faster

That could be it. It has been around 90 degrees. My last tank was 15.9 mpg. All the filters are changed within a 1000 miles ago. Just seems kind of strange when i was getting 18-19 mpg and then 12.
