I run FPPF Total Power in all of my diesel fuel. Wouldn't have it any other way. The primary benefits are fuel system life and combustion. Minor MPG gains help offset the cost which is just pennies per gallon of fuel treated.

I buy my fuel 500 gallons at a time and store in an outside storage tank. I run Amoco Premier #2 non winterized whenever possible and treat myself with FPPF. My present batch is the afformentioned blend, but I'm getting low and will have to buy some winterized fuel by the looks of it....
