Re: Ford 2010 Diesel or Gas
We have a 2008 and now have 23K miles on it and the 6.0 has run flawlessly. We have a very heavy EB and generally get 15-16 mpg while on the highway. Our worst tank was just under 14 mpg, while climbing over Engineer Pass in Colorado on this tank we had a lot of off road steep climbing and were running the heater every night (also diesel). I drive the van very gently and typically don't drive faster than 65 mph on the highway for two reasons. One is fuel economy and the other is this is a very heavy truck and I don't want to try an evasive maneuver in a 10K+ lifter 4x4 van at 75mph!
The diesel is definitely noisier than the gas. It is most noticeable in around town or off road driving. On the highway there really isn't much noise other than a slight whine from the turbo. Two things we have done which have cut down on the noise dramatically, running Amsoil and burning a bio-diesel blend or running an other lubricity additive.
The primary reasons we got the diesel is range. With the 46 gallon tank you theoretically can go almost 700 miles on a tank of fuel. There is some debate on how much of the 46 gallons is actually usable but we have gone from Reno, NV to Portland, OR on one tank and it is really nice to pass up all of the podunk gas stations with $$$$$$$ prices.
One last thing if you go through with the diesel I would strongly advise you to either have SMB install an auxiliary trans cooler or install one yourself. The Ford emblem in the grill blocks most of the air flow to the stock cooler and in hot weather ours would boil the fluid out the breather vent. I did a write up on our installation on the forum, you should be able to search and find it.
We are very happy with the diesel and if give the choice I wouldn't change.
