First long pull
Pulled yesterday ( 400miles) with my new to me 99 f250 sd. Pleased with the power but a bit disappointed with the fuel mileage (9.5 mpg ) when we stopped at 300 miles. Do I have an unrealistic expect...

This time of year your running government mandated B20 biodiesel. Milege will improve if you can find straight No.2. Ha,ha.
hugh???? what gov't mandated B20 bio, surely you are joking. B5 in some states, but that's it.
but what I can say is that B20 has virtually the same BTU content/gallon as number 2, higher cetane rating, better lubricity, and in oregon $.30 less per gallon. When I run B20 in my duramax I don't see AMY measureable difference in mileage, up or down.
As long as the vehicle is approved for it no reason not to run it IMHO
