Despite Brent's experience, the 7.3 is a good engine if its properly maintained. I had a1999 E350 with the Powerstroke 7.3 that was stil going strong at 340,000 km. The guy who bought it has put another 150,000 on it without major problems (he did replace the turbo and injectors at 410,000). I always changed oil at 5000 km intervals, kept the coolant topped up with the Motorcraft inhibitor, changed fuel filter every 50,000 km and used clean diesel. It pulled a 12,000 lb trailer about 20% of yhe time. On the highway I got 18-20 mpg (Canadian gallon conversion, so about 16-17 US equivalent). I know other 7.3 owners who've exceeded 500,000 km (300,000 miles) with no problems. They don't have the inherent problems that the newer Ford diesels have experienced, especilly the 6.0.

Good the 6.0l was once the development from 7.3l, and many will say the 7.3L is more accountable, despite the fact that that may be a bit untrue. When the 6.0L first came out in the 2nd 1/2 of the 2003 mannequin yr, there was a problem with the pc that Ford did not have a fix for right away, but they fixed it with a reprogram. It gets somewhat higher gasoline economy than the 7.3L, it's much quieter, it has more power(although it is a smaller engine and has more filter programs that regularly rob power from engines), and it can be more moderen. They've recently long gone to the 6.4L twin turbo on account that of governement mandated emissions laws, once more a greater engine than the the latter 6.0l. The largest difference you can in finding is the addition of a chiefly made 5 speed Torqueshift transmission-almost bullet proof, and also you will not to find it on the 7.3L truck. Both approach you go, you're getting one hell of a truck with a first-rate engine in spite of which one you go together with.

Don't expect miracles these days. Most 7.3L's are long in the tooth. My dealer owner/mechanic friend has a couple of 7.3L PowerStroke trucks. They get about 10-12 MPGs no matter what.

His 6.0L trucks get him 15-21, depending on the load. He pulled a school bus with the 05 F250 and got 15 MPGs minimum with power to spare that 7.3L can only dream of having.
