Any web search of the infamous Ford Diesel will let you know, its not if but when you will be spending a lot of bucks to rebuild the engine. Removal of the entire cab is necessary to gain entry to the engine. A defective EGR, Oil Cooler or over boosting Turbo Charger are all blamed for the head bolts stretching, and allowing the heads to left when the compression gets too great. The fix is spending $3,000 to $8,000 for new head gaskets, checking or replacing the heads, $1,000 to rebuild the Turbo. Replace the oil cooler and EGR, just in case. The 2008-2010 get terrible gas mileage and the 2011 needs a urea tank filled every 3,000 miles

We lived at 8500' elev. when I bought the this truck w/6.0 Diesel. It produces a lot of power at hi elevation. Easily hauls a 3 ton Bobcat on utility trailer up hill. The injectors are sensitive to dirty oil and fuel. Had to replace injectors after ruining them with biodiesel extended oil changes. Upgraded to Elite Diesel Stage 1 inj and new flash. Now change oil every 3000 mi or less, use Seafoam fuel treatment, and engine is much happier. Burnt up one alternator at 84,000 miles. Replaced it myself in 10 minutes for $200. No other repair problems. Mileage around town is 16-17 mpg. Highway is 22-26 and truck is comfortable on long trips.
A Harley-Davidson package can now be had on the F-250. Other changes worth noting are a new keypad mounted above the driver door handle when equipped with the Advanced Security Group and the availability of foglights on 4x2 XLT models. The full bench front seat is now offered with a recline feature. Trucks sold in California now have a standard 3.73 rear axle, and trucks sold in New York or Vermont require California emissions. Diesel emissions have been lowered as well.
