    Has anyone used agricultural diesel in the 6.7? Does it get better mileage? Any drawbacks?

    I drive about 40k miles a year all interstate. Does anyone have any suggestions for better mileage? Currently getting high 19mpg to low 20 mpg.

    Fine if caught on highway use of red diesel.
    Has more particles of black sludge in fill ups. I always used Goldenrod Particlate and Water Block Filters on Red Diesel.
    Diesel today is ultra-low sulfur has less lubricity. Add 6oz. Low ash 2 stroke engine oil. I use TWC Spec. For 25 gallon tank.
