2006 or 2007 fuel? What is better for 2006?

[Jeepinjason]

My local QT carries both fuels. Any ideas on which is better for the 5. 9L? Any difference in MPG?

Low Sulfur Diesel (LSD) will give you better mpg and lubrication vs. the Ultra Low Sulfur Diesel (ULSD). ULSD is the new stuff. I would definitely use the LSD.

everywhere I go around where I live has started selling the ULSD, and, i've notice about a mile less per gallon of fuel, compared to the LSD. I was getting 19 M. P. G. , now I am getting around 18-18. 25. Short and sweet, if you have a pre-07 and have the ability to buy LSD, it's more bang for your buck.

Thanks for the help guys. I think that most of the truck stops still sell the old stuff if you fill at the big rig pumps.

I can't tell any difference.
