What Oil is used in Alon A2 Nose wheel and Main Gear Oleo’s?

Main gear could be 5606 or Dot 3 or 4 brake fluid depending on if the gear has the o-ring or cup seal installed by STC. O-ring is 5606, cup seal is brake fluid.
Nose strut is 5606

According to the service manual available from Univair both take MIL-H-5606 AM2 or equivalent. Even though the manual is pretty sparse I'd suggest adding it to your tool kit.

I’m going over an Alon A2 that is relatively new to me, and will soon be topping up the Master Brake Cyl and the nose gear and Main gear Oleos. My question is do they all use the same fluid?
If so, I presume that would be Mil Spec, 5606?
Is there a brand or specific type preference to buy? Thanks and Happy New Year to all!
