What do you guys do during the winter to prevent gelling? I run #2 and run fuel treatment and have never had a problem. I've been told I need to run #1 and treat it. I've also been told its hard on stuff to switch back and forth from 1 to 2. Along with the added price of 1 and treating it seems much more expensive, do I need to do 1 and treat? I've never had a problem in the past but don't want to have any. What do you suggest?
