I have only ever used Howes and Power Service due to easy local availability. Seems like Power Service does a better job at preventing gelling than Howes does. I had no issues during our cold snap last week with wind chills close to 30 below; I did double up on the amount of Power Service I normally would have used. I know of at least one pickup and one tractor that gelled up using their "normal" amount of additive.

I would like to give the Stanadyne treatment a try.
