I've been driving semi trucks for 18 years in temperatures as low as -25. I've never used air line antifreeze and have only had 2 problems in that time. Both times can be attributed to not draining my air tanks. (Something that should be done daily in a semi, but something that is rarely done)

-50 is a different story. We don't see that kind of temperature dip very often in the Midwest. If we did, we'd probably have different equipment.

And no, Lisa is not a truck driver. She is a pretty face for the camera. If half of the stupid crap I've seen her do and say is real, she wouldn't last driving a truck for me.

 

Draining tanks and servicing the line dryer are two things on the big truck list daily and every-so-often lists. Have seen driers offered for sale with air suspensions (not bags). Worth looking at, certainly.

 

170000 miles on my 04 air bags and never used that stuff.. no problems either..
