The new Post-2007 engines REQUIRE USLD. That does not mean they can't be improved by the additives apparently. I ordered a gallon of Optilube XPD and will use it this year. I have good baseline data and the only changes will be the additive.
We plan on over 10,000 miles towing in 2013, so I will let you know if it was a waste of money.
Herk, I've been using Stanadyne for sometime now and I must say it has helped increase my fuel economy by about 1.5 mi.per gal. I always hesitate to tell people about the increase in mpg; some just never believe it.Quiet honestly I drive like I really want good fuel economy. I just don't push Max. all that hard. OPTi-Lube XPD looks good as well. By the way I use Stanadyne in my 27HP. Diesel tractor as well and my old 18 hp yanmar tractor. . Just me.

I see they have four different formulas. Which one do you use? I am currently using Power Service but would like to give the Stanadyne a try.

I found a great price on the Stanadyne. They are offering free shipping and 10% off today. Works out to be about $5.90 per 16oz bottle (case price). I went with the Performance formula. After reading about the different formulas it seemed like the most complete one.

I'm interested to see your results. I haven't done any true testing, but I feel it helps with MPG and regen's.
Herk, I'm thinking your gona need more than a gal. I use DK grey bottle in my 03 7.3 Ford every top off. I think (cant remember) it calsl for about 8oz for my 38 gal tank. I'm not that exact on the quantity I add but havent had any injector issues, yet. I don't have a base line of before/after results, I just use it. I don't believe it to be snake oil.

1 gallon treats 512 gallons of diesel (1/4 oz per gallon). At 12 mpg (what I get now towing) is 6144 miles. If it works out in 6000 miles (I should SURELY know by then), I will buy the 5 gallon pail.
