while we were in Texas in January we took on fuel at the Flying J north of Houston .... while I was standing there I noticed that it was 20% bio diesel and that there was no other choice .... while I couldn't tell any difference in the sound or feel of the truck going down the road, a drop of almost 2 mpg (when you are only getting about 10 to start with) which clearly told me that our truck doesn't like the stuff .... hopefully I'll not make that mistake again
