The Lubrizol article says that bio is a magnet for water, and there is no regulation on making it. There is also no federal standards on diesel fuel like there is on gasoline. You could be buying 35 cetane fuel because alot of states require no posting. Where I live in Pa. some stations post and some don't.

 

I have been driving Over the road since 1983 and I will attest to the fact that OTR trucks do in fact have gelling issues, since some are fueled down south and head into the colder regions before needing to be refueled.
I have been adding a fuel anti gel addittive on my old truck and my new truck as where I fuel. I get the dear in the head light look when I ask if they have a winter blend. Once diesel Gels it forms a wax, We used to mix 5 gallons of gas per 100 gallons to disolve the wax and get it to ungel. Not sure I want to try this on my new truck but if worst comes to worse I just may do it.
I also believe ULSD has a huge part in the gelling problems being seen currently,However you could NOt get an honest answer from anyone in the diesel refining industry on this. So Yes even though I am fairly confident where I fuel it is a winter Blend. I still used the Power source white bottle everytime I fuel and as of yet NO troubles with gelling. It has been -12 here and been starting just fine without plugging it in. just My 2 cents worth hope this helps.

 

I think it's the bio content moreso than the ULSD. Regardless, it still s/b the responsibility of someone, supplier, station, whatever, to supply a fuel that will work in the local climate. As far as the problem with buying fuel in the South, then heading North, well, that's been a problem as long as there's been over the road trucks. The driver should plan on additives. JMHO.

As my profile says, I'm South of you in Bloomington. What does "get a chapter going" actually mean?

 

I don't think that it's the ULSD, but alot of stations are getting fuel that has more & more biodiesel mixed in. This definately will raise the temp at which the fuel gels at.
