Terrific stuff, and order filled and delivered quickly. Use it in my 2010 BMW 535iT xDrive wagon when rebuilding the rear liftgate hydraulic pump. The best!

Q: What is the Anderol Royco 756 hydraulic fluid?

Royco 756 has a 4 year shelf life.

Q: What is difference between MIL-PRF-5606 and MIL-PRF-5606H? H means Hydraulics? or revision code?

MIL-H-5606 is used when the container has a removable top, and MIL-PRF-5606 is in a sealed container. The PRF specification indicates it is "Super Clean" from the manufacturer, and requires that the can stay sealed. We do can down the PRF material to re-sealable containers, but they have to be listed as MIL-H-5606A material.
