Like most guys i too went for the 2006 PSD for one reason, its long life. Now with the ULSD and all kinds of additives do you think the motor wiil start to run short. And if we use them do you need it at the start. Can starting later make motor problems?. Ending its life far to short. Something for all of us to think over.

I'm not too worried. Even with the old fuel, I added a mix of Marvel Mystery Oil and Power Service to the fuel for my Dodge. This was to protect the fuel injector pump. I'm still doing this with ULSD, so I have no reason to suspect that my fuel pump is being deprived of necessary lubricity.

TIMETOGO, I do hope that you get the long life from your PSD that you hope for. AFAIK you have the same fuel injector pump that my Dodge has. Keep IT happy, and the rest of your engine should be happy, too.

Like most things that change so do assumptions on how to "adapt" to the changes. All post are intended in good spirit and helpfulness. But, the fact remains if you read your owners manual regarding the new diesels and the new low sulfur fuels they say no additives should be added to the fuel. I have a friend who is the local Chevron distributor. He told me Chevron has additives to the low sulfur fuel that more than compensate for the lack of sulfur. Ford is the only truck (GM,Ford,Dodge) using the new piezo injectors. chevron says "motorists can expect a 2-3% decrease in fuel economy with the new low sulfur fuel". The fact of the matter is fuel changes by the seasons. Winter or colder climate cause engine fuel milage to drop. The fuel blends that have been used in the winter have for many years caused a slight drip in mileage. I kept track of a fleet of trucks for 25 years. The fuel economy dropped about 6% in the winter every winter. GET THIS....regarding dielel and gas blends the industry slang, there are more than 600 different blends of fuel used in the US. Each reagion, city, weather change,etc. Fuel additives in spite of what some say rarely do much except drain your wallet. I KNOW>..We tried them many times.....only result was we spend more money to get the same MPG. Service is the key.....clean filters, oil etc. Sometimes additives will clean up injectors a bit......if they are clogged. But injectors will not clog if good fuel and good maintenance is used. Water is the biggest enemy of diesel. You can't let diesels set around for months on end and expect them to run well. You can't store diesel fuel for very long without issues. A good friend of mine has a cherry and peach orchard. He cusses his 7.3 ford diesel. It never did run right according to him. Of course HE has a thousand gallon above ground fuel tank and the fuel sets in it all winter. He uses it for his tractors and his 7.3 liter Ford. He has more problems with things than HE admits. He buys fuel in bulk to get a discount. It sometimes sets in the tank for 6 months or temps from below zero to HOT. HE traded his Ford diesel last summer for a chevy. GAS. He brages now that the chevy runs fine...HE buys the gas at a station. NOT from a tank on his farm..NO wonder. Some people just find ways to have problems.

With the sort lived 2007 ford 6.0L psd (i think may). The new 2008 will be a little bigger, 6.4L Maybe from the loss in power with ULSD the larger motor made up for it. More HP means less steping on the gas = better MPG. I think the only thing we can do is, do the p.m. and drive the truck.

I've noticed a 6% decrease in my fuel economy over the last several tanks of fuel. I've changed my fuel filtors, and drained my water seperator. My driving patterns haven't changed. I'm not sure if it's the new diesel or something else. I've just turned 30k miles on the Excursion, and was hoping for an increase in my mpg, not the other way around. Oh, I was getting right at 16mpg in town, and now it's under 15mpg.

Tom, we run very similar rigs (X 4x4, 34 w/so). For reference, I just drove down to FL (without towing) and got about 17 mpg on the highway, although around town is probably closer to 15 mpg. On a recent cross country trip towing, I got about 11ish mpg. My X has about 75k mileage. I have not noticed a change with the low sulphur blend.
