Was in the teens here last week and I had no problems with B20. Will definitely help if it's specifically blended for the winter temps though. A couple guys I know run B100 year round and have been just fine down to about -10, hasn't gotten any colder than that for them to find out how low it'll go.

I really depends on what the biodiesel portion was made from. I don't think that at B20 you'll have any trouble down to 10... I know my B100 from waste oil isn't good much under 40 (I don't trust it anyways...)

What you can do is put some fuel in a jar and leave it sitting on the window ledge outside...then you can get a good feel for how that fuel reacts to different temps.

throw a quart of Power Service white bottle in with each 30 gallons, never have a problem.

Here's an article out today from NBB on the topic.

Do they have fuel pressure gauges to verify it's flowing well at those temps? Do they have fuel filter heaters? If not, they are waxing their filters. All B100 clouds at those temps. Canola based fuel has the best cloud point.


As for the B20 of the OP...if it's quality bio mixed with winter #2 you'll be fine.
