I am not really doing any testing yet, just taking the truck for a spin as often as I can to keep moving the injector cleaner through it and the engine cleaner. I have a route that I have been driving that really isn't going to work for MPG testing, but since I finally have the UG dialed in I slowed down and payed attention tonight. The loop I am driving is 19.3 miles, there is are 16 traffic lights, and the spaces between the lights vary between 45 mph to 65 mph. The drive out on this loop is a climb in elevation of probably 500-800 ft. I am at a higher elevation here so that may be an advantage as far as fuel economy is concerned. Still no real ecomods to the truck, but I kept the speed at 55 on the 65 mph stretches of road and looks like the round trip economy on the UG is reporting a 34.4 mpg. I will try some runs at the PSL and see how that looks and watch the impact to the round trip. Of course it will vary by the number of lights I get stopped at and the amount of traffic. Tonight seemed to move somewhat smoothly even with traffic with only about 3-4 stops each direction for about 6-8 stops. This will at least give me some ideas of what to expect as I move to the next steps in the ecomods.
Right now I am still working to flush a couple tanks of fuel through the truck with cleaner and a another engine flush and oil change once I have completed the fuel cleaning routine before I start the ecomods. Not sure if it will be the synth fluids or the tonneau cover first... I guess I will flip a coin. :-)
