Low sulfur fuels
I have a 1993 F-250 7.3L engine. Do the low sulfer deisel fuels cause the o-rings in my fuel injectors to leak? And will it cause other problems? And, what about the ultra-low sulfer fuels for 2007?

I would suggest contacting your local Ford dealer or even better a good local diesel shop to see what their take on ULSD (S15) will be on your 1993 7.3L. Another suggestion would be to see if you can use a biodiesel blend such as B2 or B5. Either of these blends should resolve the lubricity issue, but they could cause a problem with O-rings.
I drive a Jeep Liberty CRD and it is designed to run on S15.
The oil companies have been making ULSD for years in Europe. Don't take my word. Go to the forum at Fred's TDI. Do a search on the subject and you will find tons of good information there. I also have a Power Stroke and a Passat TDI and I'm very please to get the new low sulfur fuel.
To the person (or people) who says ultra low sulfur diesel won't hurt a Ford Power Stroke: By you saying "hurt" I am assuming you also mean dirty diesel dripping all over a clean motor and driveway. Are you sure your getting ULSD and not LSD? Well you better do some research about the current events ma-man. Myself and my family live in Phoenix, and the ULSD is a very recent change to our pumps. My dad and my mom both have 7.3l diesels, one in a 2001 E350 15 pass and my dad has the 2000 4x4 Crew. Both are retired, and BABY thier vehicles. My mom uses hers to run kids back and forth to school,(Its a wheelchair van for disabled kids). Both of their vehicles have less than 70,000 miles. About a few weeks ago in early Oct, the van accumulated a puddle of oil overnight. They took it to Ford, and luckily the extended warranty they bought covered the problem. Apparently the O-rings on the High Pressure Oil Pump leaked. Fixed, and still not leaking. Oct 17th (Tues) Now its a puddle of fuel! Now it gets frustrating. Ford DID NOT pay for the $500 Water Separator. Well it gets worse. Dad discovered a puddle of fuel on the driveway yesterday (Fri). Haven't taken it in yet. I would bet money that this is going to be well known throughout the country quick. My dad had 240,000 miles on his 97 F350 with only one injector leak. I have a VW TDI (2005) and no leaks yet. The logic behind this is simple. All the fuel comes in from one spot in Phx called "Tenders". Both ULSD, and LSD came in simotaneously until the permanant switch to ULSD was made. I feel bad for my parents and everyone else that has weak O-rings in thier diesels. I am also concerned about the hot streets of Phoenix with ULSD leaking all over the ground. I have heard in some of these posts that a 50/50 biodiesel/ULSD could work. Using a lot of biodiesl would get a little pricey. Is it just the fuel in Phoenix? Does someone know what can actually help? What about all of our emergency vehicles? This is an obvious problem we can't ignore. HELP FORD!
If it does, I will get another diesel truck other than a Ford.
What I'm really saying is the spin against ULSD is a bunch of junk..............................
There have beeen some complaints of older powerstroke and Cummins engines having injector pumps leaks from the ULSD.
Most of the problems have been in pre-2000 diesels.
On older (pre-97) 7.3L Fords, with return hoses that weren't in the best of shape, the ULSD has caused them to leak. While this isn't attributed solely to the ULSD, it is something for folks with older Ford diesels to be aware of.
