Has anyone out there in the northern states had problems with the expansion
characteristics of 5606 hydraulic fluid ? It seems that my up pressure
switch sticks increasingly worse with the decrease in the temperature. Is
there some nice military substitute for 5606 for those guys in Alaska ?  I
would hate to just adjust my up pressure switch artificially high to make
things work for the winter. It might not be so good when I fly to Sun & Fun
and transition to80 - 90 degrees !  The pressure switch is the first
generation 1988 ish adjustable.


Thanks
