I was introduced to Power Service products after repeated injector failures in my 2006 6.0 injector problem after injector problem for the first 75,000 miles. After the last injector I decided to add Power Service to each tank of fuel, I notice a quieter engine shortly there after, but most impressively I never had another injector failure or fuel system problem again, I sold It with 325,000 miles in it.
