How cold is to cold for B20?

I ran it for close to 2 years in Ohio, we had 1 real cold winter and 1 that was normal. Used it in about 32F/0C, all the way down to I'd guess 20F, whatever that breaks down to in C. I always plugged it in when I was running it for at least an hour for the engine block heater, and never had a single issue.

It really depends on the base stock used to make the biodiesel. I have had B20 wax my filters with temps in the 40*F range and I have known people that were able to run B100 down to 0*F and below without any problem.

Yeah, put a location in your profile so we know where you are. If you're in Fl you're good all year. If you're in Canada you're probably not.

I don't know what else to add. Check with whoever is selling the B20 in your area and see what they are experiencing. It is often hard to find out what the biodiesel is made from in many cases.

The people I know running B100 at 0* and below are running home made bio from canola oil stock. The commercial bio that I used to be able to get here had a fairly high amount of animal fat and PHO base stocks.

Go here and read Chapter 4. Might be helpful.
