falling MPG's but not power

[SixStringMadness]

My MPG's are dropping from 18 - 19 down to 15 - 16. I have. When I could go 500+ plus miles per tank, I'm now gettng a little over 400. No black smoke, no long hard starts, just lots of highway driving. This is frustrating as a MF'r, and I'm getting tired of it. I just want to drive this thing and not worry where the next $1000 is going.

Probably the winter diesel with the anti-gel formula. Sorry man but that's just the way it is for now.

so the anti-gel would have that big an impact on fuel mileage? Ain't that some shizz

I wouldn't think that would be my problem. I still had half a tank from the old filters to use after I changed the fuel filters. So Idk why mine is doing it.

Nil on the anti gelling. I'm in Knoxville, TN where Pilot is based, jsut called the corporate office, and they say no reason for the drop. I get fuel at the biggest Pilot in town, they move so much fuel through there, there is no reason to have a fueling issue with my fuel "according to Pilot"

They will prolly not admit its the winter fuel.

He also stated they don't have a "winter blend", jsut an anti-gelling agent. It's not cold enough here to need "winter blends"

according to him the anti-gelling agent and winter blend are two distinctly different things.

I've read that for the winter they mix Diesel #2 with Diesel #1 at the refinery. don't know the difference between #1 and #2 but that's what I read.
