Internal glazing and carbon buildup is due to prolonged periods of running at low speeds or low loads. Such conditions may occur when an engine is left idling as a 'standby' generating unit, ready to run up when needed, (misuse); if the engine powering the set is over-powered (misapplication) for the load applied to it, causing the diesel unit to be under-loaded, or as is very often the case, when sets are started and run off load as a test (misuse).[16][17][18]

I guess I am going to have to go on more road trips. Fortunately, the first 75k miles on my 09 were 90%+ highway. But in the last 7k miles it has been reversed, mostly city.
I have started using that Amsoil injector cleaner. It's recommended 1 oz for every three gallons of diesel, so I picked up a 4 oz and a 1 oz bottle from the container shop (so I dont have to measure out the right amount at the pump). I fill the containers before I leave for the gas station, then I use the plastic adapter which came with the car to pour the injector cleaner, then fuel it up to mix around the injector cleaner.
