I am not a Fan of Pilot/Flying J fuel since most of this is 20% Bio-fuel for sale. This tends to lower my towing mileage as this has less energy content than Low Sulfur Diesel Fuel has. I tend to run no more than 5% Bio-fuel, as this is what Cummins says is acceptable for my year of engine.
When we travel I do advance research on the fuel stations in the area where we will be fueling up. I only stop at stations who do not have high levels of Bio-fuel for sale. I also tend to avoid states that mandate high levels of Bio-Fuel must be sold. One of the reasons for using the "Next Exit" as this list all fueling points along the way.
