That's my story:
I have always wanted a diesel truck and about a year ago I came across a 2006 Ford Super Duty with just under 100,000 miles. I know these motors can go well over 250,000 so this truck was barely broken in and I went ahead and purchased it. Over the last year I have noticed that the truck became sluggish and was knocking. I kept driving it and then noticed that the fuel economy was getting worse and worse. I had to do something. I started to research what I could do online and came across incredible reviews for LIQUI MOLY products. I looked on the LIQUI MOLY website and noticed that they had a full line of products dedicated to just trucks. I purchased the Truck Series Complete Diesel System Cleaner and wow what a difference. My truck runs amazing and the fuel economy is even better than when I bought it. Thank you LIQUI MOLY for making products that work and are designed for us truck owners!
