Nezar: That is a very interesting occurrence. Are your referring to the aftermarket power steering fluid? Any quality ATF fluid should be OK. As far as tighter and tighter steering after starting, I'm not sure of the exact cause. It will requires some investigation.
Could be degraded/dirty ATF fluid; defective power steering pump; worn/loose serpentine belt; or others. You'll have to go through and check/eliminate the possible causes. You're in a harsh operating condition, dust/sand and extreme heat reek havoc on machines.
I would try changing out the ATF fluid first. It's cheap and easy to do.
