I just put in 19 galons of low instead of ultra low in my 08, the sales rep at ford said to just keep toping off the tank until i burn out the low sulfur. Has anyone had this issue and is there another fix besides draining the tank? additives?
I actually got into a spot a couple times with the low sulfur (500 ppm). I believe the book says damage to the DPF will ocurr if using any fuel higher than 500 ppm. I haven't had any emisson related problems. It does make for a better smoke screen during the regen.
