Sudden drop in MPG?
F250 5.4 V8 257km
At the start of October I was getting 530 KM to the tank, now I getting just over 400 KM to the tank. I was wondering what would cause this? I do all my maintenance well before scheduled maintenance is needed.
Thanks

Being in Canada, I bet your fuel is already winter blend. Winter blend fuel usually begins in September through November, depending on where you live. It has an effect, though I don't know how much of one.
Good luck!

Not sure of the answer either but that's a bunch of decrease in milage. That sounds way too high for the winter blend switch. Try posting in the 5.4 forums...those guys may have an answer for ya.
