I sat a jar out of B50 last night. it got down to 14 degrees and I could see some cloudyness in spots. I have a full tank of this in my truck, Is there anything I can add to it to keep it from gelling

I'd siphon out 5 gallons and replace it with Kerosene.

Everything I've read says that you can add either Kerosene (#1 fuel oil) or Diesel (#2 fuel oil) to help.

You could probably also use a small portion of unleaded gas if you wish.

Kerosene would be a lighter oil than #2 Diesel which may have benefits.

I don't know the proportions, but you will have to make sure that it is well mixed as pouring one on top of the other in the tank isn't sufficient.

Some kind of heat exchanger would also help.

Just dump in the Kerosene and drive the truck around a bit. That will mix it up just fine.

I had room in the tank for another 3.24 gallons. I added dino to top it off. I figure im at about B44 currently. I'll have to siphon some fuel out tonight and check it as this morning it is 2 degrees. Man it never gets this cold. I just worry about it being water in the fuel. I find this to be odd. I have a jar of B50 sitting outside and it is cloudy currently at 2 degrees. Then I have a jar of B100 sitting in my garage and it just barrely has a haze at the bottom of the jar the rest is clear temp of 34 degrees. you would figure the B50 would have a cloud point of a lot lower temp.

At 18F my b-100 was solid and my b66 looked pretty good... I mixed 1/3 with #2 D

B-100


B-66
