anyone getting new fuel leaks after using ultra low sulfer diesel in the 6.0? I have several friends that are having problems with their 7.3's?

 

How old are their 7.3's? The older the seals, the higher the risk of fuel leakage.

I'm on my third tank of ULSD and no problems. But then again, my engine is still pretty new.

 

i'm only on my second tank of ultra low sulfur..... but i swore it woke up at least two of my injectors my truck seems to have more power by my butt dyno...but i think its just me

 

I have almost 70,000 mi on my 6.0L and have been running ULSD for a number of months with no problems. I do add a shot of PowerService in with each fuel up, but I have done this since new.

 

one unit is 2002and other is 2001 both around 100,00miles, but I have seen lots of talk in the 7.3 forum about new leaks. hope we do not get them.

 

We have been using it in Canada since April of last year. Government had our refineries change all on road fuel over since then. Haven't heard of any problems yet.... We aren't using the same pumps stickers as in the US. Some pumps say low, some say Ultra, some say nothing at all. It is all supossed to be ULSD though.

 

The new fuel is not causing the leaks in those 7.3's

 

so admin is there another explanation?

 

Age of the truck!

Absolute coincidence!

 

I totally agree . Seems some folks just need something to bitch about. Must be ULSD turn. This too will pass in time.
