I bought the truck in Minnesota in February at an auction from the military. The vehicles sit a lot and it was cold and hard to start. It ran ok but didn’t seem to have good power. I stopped at the first truck stop to fuel up and find some additives for the fuel. Luckily I bought Diesel Kleen. With in a quarter tank it was running smoother and had better power. I drove it all the way home to Washington state. I now use it in my Ford 7.3 and an older diesel army truck. They all run great. Thanks for a great product!
