My fuel economy has stablized somewhat. Still getting over 20mpg running 75mph but around town mileage is still down. Also noticed a difference in economy between the different brands of ULSD. My best is with Murphy (Walmart) and the worst so far is with Chevron.

I live in Kansas, and the new ULSD Diesel fuel is here at every CO-OP, BIO Diesel is 34 miles one way to get. My 01 Dodge 3500 has had 3 tanks of ULSD and so far no problems. My ? is why does the pump say not to run in anything older than 07 Engine or it will cause engine damage.

According to OOIDA as of October all fuel feed lines had to be 80% ULS. It takes a while to flush out the lines and tanks, so they can't advertise the new stuff until it is pure.
My N14 lost the better part of a mpg in the last month or so. The mileage is worst at Flying J (ipoff)

I think it is winter blends causing the drop in MPG, but I can't be sure yet. Every year we see people complaining about a drop in MPG this time of year and they blame it on everything from batteries to airfilters. It is the blending of the fuel to keep it from gelling (at the pump) that changes the fuel to lower the MPG.

check out prices noted at start of this thread.... $2.79 vs current $4.09 in tulsa. this is on top of mileage drops..
have switched to running 50% motor oils, my power is up and mileage is back up.

I have been using Lucas Upper Cylinder Lubricant and thought it was a great product. I read a new study on Lubricity Additives on dieselplace.com and think I may be wasting my money. Anybody have any comments on that study? I have never even heard of Opti-Lube XPD but am thinking of trying it after reading this study.

I have been obtaining 21.1 to 21.2 hand calculated for the last couple 400-500 mile tanks. Will fill up in a few days and advise if the Opti-Lube is all it is cracked up to be. It does seem a bit quieter...

My truck hardly ever sees ULSD unless I'm really low and don't think I'll make it to the truck stop where I get LSD. On the few occasions I have filled the truck with ULSD the truck DRINKS it. I have not calculated the difference but it is noticeable just from how fast it disappears.

opti-lube and stanadyne additives (among others) have a high solvent content, and some believe that additives with a high solvent content will cause long term damage to injectors and pumps. BTW increased fuel mileage is not necessarily a good way to judge the quality of an additive, because a product with lots of acetone will give you better mileage, but too much acetone can damage your fuel system.
