Chuck, My experience with Bio Diesel was not good.  Took on a tank of it in Wisconsin, a couple days later fuel filer was clogged with gunk and shut me down, guess Bio loosened up all  the crud.  Got much better mileage that tank but in the future I won't use BIO.

I'm guessing we are dealing with extremes here. If ULS diesels has less lubricity, instead of a engine going one million miles before needing a rebuild, it might only go 900,000. I doubt that the miles most of us put on a motorhome will be enough to require supplemental lubricity. IMHO

But didn't it make you feel good that that crud was no longer in the system? ;D  Did you have to change filters more than once?

Hard to say for sure but I expect you're right as far as the combustion section of the engine goes.  I'm having a hard time seeing where the reduced lubricity of ULSD would make a whole lot of difference for cylinder walls and rings.  However, when the man on the other side of the counter says "that'll be 3200.00 for your new injector pump" well that's a whole other issue.  I've replaced several on Cummins powered pickups with relatively low mileage, engine far from worn out.  (I certainly did not pay 3200.00 for my rebuilt pumps for the 6b, I'm guessing at what the cost would be for an 8.3 Cummins, new pump.)

I use bio all the time. It is only at 10 percent but it does clean out the system.

Had to change fuel filters twice after using BIO.  And reman injector pump on 8.3 was 1500 bucks plus labor, also have replaced lift pump twice.  Hard to say how much was due to ULSD, but injector pump failed at about 90K miles.

My breakdown is;
1. cold fuel
2. Lubricity
3. bugs(aglea/fungus or whatever!)
-------------------------------
#2....Lubricants to me seem really important/even if I do not know what it totally means...( I want my engine to be lubricated.)
#3....I use Biorbor now since 1985/so 27 yrs. successfully.
NOTE: I have been a 'cruiser' using fuel from most everywhere on the East Coast of the U.S. and Gulf of Mexico and 5ooo miles of rivers from Moblile Alabama up to Kentucky and both big river of Tennessee. Also 7 years of crusing 3rd World Countries.

That said. Using 2 cycle Oil and the best oil, Dello 100 for break in/400 next and now Mobile 1 Synthetic...
-Double Magnets inline(not sure if anyone has gone there or wants to)..I'm happy!
-BiorBor (bug stuff)

I use a double Racor #500 filtering system I devised/to not only clean fuel as it was needed but to clean it when we sat at the dock(another issue)
I use a 2 micron filter as the FIRST one then have a back up of a 30 Micron filter if I ever have a problem and have to "Shut down" or shift FAST.

20 years now, my fuel from maybe 50 sources in 7 countries with probably 12 sources. have ONLY required me to change out a filter ONE time....and that has been a 2 micron filter!!

I am stating this because, "We" could not call Good Sams if we had a problem......we might die if things went bad.....
