Just found out the local Loves has biodiesel. Has me wondering if a little in the scar test was good would running it straight be better. But
this say
That has me thinking it would be a bad idea in the winter. How could they sell the stuff to truckers or anyone in the winter if it causes problems at freezing ?
I've learned a little about this topic, still have lots to learn though. Suffice to say, one of the realities of ULSD is that the lubrication property of the fuel is not the same.
You'll find various opinions on how to treat ULSD (ranging all the way up to flamewars, on other forums); IMO the key things are:
1) Recognize the problem.
2) Do enough research to begin to understand
what is appropriate for your vintage of diesel. As a safe place to start, good quality products like Stanadyne have endorsements from major OEM diesel engine manufacturers.
Ex. - if you live in California, and drive a 2013 diesel, the solution that works for a Manitoba farmer may have you replacing REALLY expensive emission components the next time your diesel is tested.
I think biodiesel
can be a good solution, IF you have a consistent good quality source AND don't run really high % Bdiesel right out of the gate. (Biodiesel tends to clean out normal deposits in a fuel system; done too rapidly and you plug a fuel filter).
For my older 7.3, if/when Biodiesel becomes more common here I want to start out with B5 in the Summer.
For lube, some guys just run a good quality 2 stroke oil. Again, you likely won't get into too much trouble doing that on a 1970 era diesel Ag tractor; a late model Ford, Dodge, or Chev diesel p/u might be another story,
esp. if you have strict emissions testing in your area.
Another popular solution that did well (from memory...) in that test is Opti Lube XPD. If I was to move from Stanadyne to anything else, that would be it.
