Myself, I'm an Archoil fan and have been for years. I use their fuel additive in my truck and in my farm tractors too and I use their oil additive in the 7.3. Made a huge difference in starting the engine and I picked up some fuel mileage as well. Not enough to offset the additive cost but a bit.
This last summer I had to replace the right side injector harness (the one that routes through the valve cover and fires the injectors and energizes the glo plugs) and did the left one as well. I was amazed how clean and free of any varnish or sludge the overhead was. Just as clean as when it came from the factory I suspect. I could see all the paint marks on the overhead and read with no issues the labels on the injectors.
Was glad I have an OBS truck. A new body style truck would have entailed pulling the cab off the access the right valve cover. It was tight, but doable with some cussing on my part.
