It's funny everyone has urged to stay away from the 6.0 Ford Diesel. I will give a real world example with the 6.0. My father owns a pretty good size construction company with about 10 6.0 diesels. Every winter the driver of the truck is required to do maintenance on their trucks in the depths of the Wyoming winter. It's a way to keep the guys working during the cold times. A mechanic shows them what they need to do and then year after year the driver then becomes responsible for the maintenance. Every 6.0 got a coolant drain and fill each winter. It was discovered a long time ago the Ford Gold coolant is great stuff, for preventing cavitation. However the silicates that prevent that fall out of suspension after a while. These silicates clog the oil cooler and eventually take out the EGR cooler and then the head gasket. Having fresh coolant in the trucks, we never had clogged oil coolers, or blown EGR or head gaskets. The 6.0 with maintenance have been some of the best trucks we have ever ordered. In fact a lot of them are getting some miles on them now and the drivers are hesitant to let them go. In my observation, the trucks that get worked the hardest are the ones with the least engine problems. The most important thing is maintenance. No truck is going to work well, especially diesels, if an owner just changes the oil. These modern trucks need constant attention to the fuel. Water in the fuel will kill a modern truck faster than anything. Always draining the Fuel water separator is something hardly anyone does anymore. Fuel filters should not go longer than 10,000 or a year. Do not put on aftermarket air filters, they let too much dirt in and will pepper the compressor wheel on the turbo. A diesel truck needs a monitor to track oil temps, water temps and other important vital components. I have access to all brands and engines, my favorite is the Ford 6.0. Nothing sounds better and pulls harder than a good healthy 6.0.
