Changing filters and fluids regularly? maybe a sensor is taking a crap, when my ICP sensor went my mileage dropped down.stumper1620 said:You are not alone,
If you figure it out let me know what you find.
I have a 02 SD 250 with a 7.3 PSD, when I got it the mileage was up around 18 then gradually fell off, last Feb I pulled my 16' open trailer 300 miles empty and only got 8.5, still have'nt figured out whats going on but the best I have managed to get back up to is 13 and occassionally 14mpg. changing fuel blends and additives have not helped.

I'am going to check the mileage for the next few tank fulls to see what I'am getting.
#1 is generally a not referred to as a premium diesel fuel. It is a more cold weather resistant diesel fuel and will yield less MPG's. In the more temperate climates you will not see #1 available at the pumps.lawnmaniac883 said:There are two grades of diesel fuel, "premium" or #1 has a higher cetane value than #2 or regular. Running premium instead of regular may result in increased mpg.
