I searched and did not find any recent topic on mixing diesel number 1 with diesel number 2 for winter temps. Where I live it can reach -25 degrees below zero! Have seen it colder a couple times. Due to this I use straight number 1 diesel which my dealer says is fine. I was always told that number 1 has less lubrication than number 2 so I put in a supplement for that. I would rather use a mixed ratio of both number 1 and number 2 vs straight number 1. So, who here uses a mix and if so, what ratio do you use and for what temperature do you expect it to work down to? Like #1 / #2 = 50 / 50 or a 75 / 25 mix? I'm thinking for me to be safe at -25 degrees it should be a minimum of 60 /40 or 65 / 35? If it matters, skid steer is not kept in heated building. I did a google search and there are so many variations I just wanted to check here. Thanks!
