Ford corporate recently told us that we need to test the diesel fuel every time before filling up our 2008 Ford diesel F250. This occurred after contaminants were found in the fuel and we now have up to $12k in damages. The truck has less than 70k miles and this is the second time this has occurred (first at 24k). Truck still under warranty. No abnormal driving, primarily highway and occassional pulling of a 3 horse gooseneck trailer. All scheduled maintenance, including fuel filters, was regularly performed by a Ford Dealer. No warning lights came on before engine shut down. Through postings on diesel forums and leasing associations, we are hearing this is not an uncommon problem.
I kept reading post after post on the internet about the 6.4 and wondering if my day would come? Well here it is. My $58,000 truck with 126,000 miles on it, with no warning except for the temp. gauge climbing, which I immediately pulled over and stopped trashed the motor. Guess I knew after Ford adandoned the motor after only three years I was in trouble. Shame on you Ford!! Thanks for no help and a $17,000 repair bill..........
I've only had my 2008 F250 a short time but I'm really impressed. It is a lot of fun to drive. It tows our trailer without any problems. I've had it out into the Texas Hill Country which was a good test. This summer I'll try it in the mountains. I still don't have a feel for MPG and diesel prices are higher. I'm hoping that my first impressions will be lasting ones. So far it's a fantastic truck.
I now have just under 130,000 miles on this truck and I have hauled tons and tons of rock, 5th wheel, and a car. I have had nothing but great performance, no repairs, and perfect reliability. I have the V8 and it has been able to haul everything including a couple of times overloaded with ease.
I do a lot of pulling and highway miles. I love the power the 6.4 has, but I am not a fan of the exhaust cleaning. Drags your MPG down. If you regulate your speed by the turbo, (less than 10 psi), you will maximize MPG. At 50,000 miles, average highway is running at 16.2 pulling around 8,000 lbs.
