Went through the settlement process, had the modification, got the checks, and my stock truck runs pretty well. post settlement. In September took a road trip with my wife up into Utah, Wyoming, and Montana. Traveled about 3,800 miles driving about 200 - 250 miles a day when we drove, staying some places two days and only one in others. Tried to keep it restful and the country was truly beautiful, lots of color. Lots of up an down and time in the mountains. Got around 30+ mpg several times. Truck ran great, no issues with anything. One thing, I used more DEF than I ever have before, actually stopped and added some, having started with a full tank. Something I have never had to do before. Is this just my experience or are others experiencing the samething? Another thing, I have never used Blue DEF, have you and do you think it works well?
