    #3? Number three diesel is a distillate fuel oil and seldom used as a motor fuel here in the USA. In fact I was not even aware that #3 was still being refined since it lacks the advantages of #2 as well as the lower cost of #4 diesel; which is mostly used for locomotives, fixed generators and some marine applications. As the numbers go up the fuel becomes heavier and it's flash point rises (though not by all that much) so if you are having problems with #2 gelling you can forget all about the heavier distiliates. #3 and #4 deisels are not desinged to be motor fuels in the conventional sense (cars, trucks, farm impliments) so I would have serious doubts that these could be used safely in a modern diesel engine designed for on road applications.

    Nealry all diesel motor fuels other than #1 will begin to gell at about 30F. B20 diesel (20% bio/80% conventional) will get you down to between 15-20F before gelling problems begin. With conventional #2 you'll either have to blend it with #1 (or kerosene) or add a specialized additive. Based on your location and your occupation I know that you are aware of all of this but I just tossed it in for those who may be reading along for the entertainment value!
