LTCF suggested that I start using fuel from Cenex. He got much better mileage. I am not noticing much mileage difference, but my motorhome sure seems to have more power. I've only had a diesel a little over a year, so I don't know that much about them.

It's true, I go out of my way to buy road master diesel for more power and better mileage.

Anyone want to take a stab a why that is?

The red stuff (field master) is even better, but you're not supposed run that stuff in your pickup

I've been buying my fuel at Costco here in Billings. For awhile it was 20 cents lees a gallon than the other stations around town. The issue that I see regardless of where I get the fuel is when they start to winter blend the fuel, then my mileage drops. Summer blend is when I get the best mileage out of my Excursion. I some times use Diesel Clean (grey bottle) and it helps out the mpg a little.

Right. They pull the paraffin out of the #1 because that's what gels so the fuel is less dense therefore having fewer hydrocarbons.
