everytime I drive across the upper midwest my fuel milage goes down. do thay put ethanol or something else in the fuel out here.

 

There should be no ethanol in diesel fuel. However, if you are driving through that area in winter you would probably be getting winterized fuel which has a lower energy content and therefore gives lower mpgs then #2 diesel. Could also be things like headwinds, driving style or speed (if it is different then you usually drive). I have often found that when I do a round trip through an area the wind is blowing against me in both directions. :-(

 

Everytime I go south--to florida--- around chattanoga I get fuel. mileage always goes up by about 2mpg. On the way home I fuel there too and it stays up ubtil that fuel is added too.

 

They must add some of that good Tenn hooch to the diesel down there. I'd fill up there if I could too. Enjoy it while you can.

 

That hooch is really good.
Not really admitting anything though!

 

Stopped in Illionis for fuel at a TA and at a Marathon. All of the diesel pumps had a little sticker that said E-11. I think they put 11 percent ethanol in the fuel there and in many other places. Did not affect my mpg. In fact, the mpg went up. But I think it was the heavy tailwinds.

Here and in many places the gas pumps have a up to 10percent ethanol sticker. I thought that did not apply to the diesel hose at those pumps. Now I think maybe it does. maybe a lot of diesel has ethanol added???

 

Sure its not Biodiesel being added, I would doubt they would add ethanol/

 

It said E-11
do not know what it meant. I thought biodiesel designation started with a B, as in B-5 or B-20.

 

There is a lot of desel fuel that has Biodiesel in it. Some will have more and it will show B-5 or B-20
