The first time I ran ULSD the many tanks before averaged 18.35 ( hwy mpg) with LSD and with the ULSD my mpg dropped to 15.8-16.04 mpg and with the high prices we have to pay I would like to have that 2+ mpg back.

Another one here getting less power and mileage with ULSD.

Gee, I get less power, less fuel economy and I pay more for it! What a deal!

I took a trip to Ohio pulling my enclosed with 2 atv's not much weight, about 7000lbs. In Canada we only get ULSD and on the way down I averaged 10.5 mpg. Filled up down there with #2 LSD and 13 mpg from there on back to Canada untill I filled up with ULSD and BAM 10.5 average again.

Just odd stuff that new diesel seems some of us are getting less mpg with it,I do add Lucus to it..

Btw in my Dodge book it says they prefer u to use #2 diesel...go figure.

I switched to K-1 with motor oil mixed in and I get the same mpgs as with ULSD. (offroad of course) K-1 is $3.25 a gallon vs $4.79

No real difference that I can see. Of course, I'm driving slower and driving less these days.
