I use the Power Service white bottle in the winter. Seems to work well.
I'm sure there are quite a few that do the job, I use the PS because it is readily available and fairly inexpensive. If you do use it make sure you read all the instructions. It talks about the mix ratio, but then goes on to say if it is getting extra cold or if being used in a pickup vs a big rig to double it. I fell victim to that in my IDI van I used to drive.
Now I just always mix it double to be safe.
Tractor sat in its tent for 3 days in below 0*F temps. Went out the morning of the first day it was over 0* and it fired up/ran with no issue.
