With the colder temps coming on, was curious about something. Assume I'm running B100 (which I am ), and now it's about to get seriously cold overnight. If I go add some regular diesel to achieve a more "cold-adverse" mix, how long do I need to run the truck to have the new mix in the fuel tank make it through the fuel lines and injectors ?

Thanks,

Not long. It will mix as you're putting it in the tank. I'd say a matter of minutes based on my observations mixing a little two cycle oil into the fuel.

 

It can't get THAT cold in Houston.......... I blend down to B-80 and don't have a problem to about 10 deg. If I think it's going below +10, I mix it down to B-50.
