Anybody been running marine 2 stroke TCW 3 in their trucks? With this ultra low sulfur BS they sell at the pump these days I started using it in my cummins, and have noticed a quieter CP3 pump. I put about 32 fl oz. of wallmart SuperTech per fill up and have a smoother running truck. I also run Diesel Kleen from time to time as well. Anybody else putting it in your pre 2007 diesel?
