ok, the answer is 15 degrees F is the critical point where things get bad. 32 degrees F is where it STARTS to gel but probly wont be a problem. had to call good ole dad (read chemical eng.) and get the answer. grant
I started both my trucks last week at 0 degrees without any additives. So even if it does gel at 15 degrees I don't see it to be detromental. I then added some additive just so I don't have any issues.
i should have put this in there... we looked at the numbers for summer #2, not cold weather or extream weather #2. they are lower. my concern was that i will be going to AZ next month for a couple days and it is getting to be 28ish at night. didnt want to pull into town with a low tank of summer #2 and have it gel up on me.

It also depends on the quality of the fuel. If you buy your fuel at a truck stop that moves alot of fuel it should be beter. If you buy it at a small local gas station It could have set for weeks or even monthes and stands a beter chance to be contaminated with water which would couse it to jell closer to frezzing point.:doah:
very true. this was just off the MSDS that my dad pulled up. im sure a low quality fuel will be a higher temp. grant
