    It gets the job done!

    What can I say, if you are looking for mineral oil-based aircraft hydraulic oil that fits the specs of your aircraft, this is it. It does what it says and I have been using it since the beginning. Not saying that the competitors are bad, I just know personally I have not had any issues with this :) Pick ya up some and give it a whirl, you will not be disappointed.

    Marine Steering Hydraulic fluid

    Use this instead of sea star brand. Has the same specs at a much lower price and the red color is a plus to find leaks quickly in the future.

    Great for Seastar Hydraulic Boat Steering Systems

    Posted by Fred M. on Mar 06 2017

    I bought this to fill a Seastar hydraulic steering system on my boat. A gallon of AeroShell Fluid 41 was within a couple of dollars of the the same price as one quart of the Seastar brand hydraulic steering fluid. The packing was superb and the can arrived without a dent. The only negative I can think of is that the can is not resealable (possibly out of concerns relating to moisture contamination). So have CLEAN, resealable containers to transfer the fluid to. I recommend something around a quart size for ease of handling and pouring. Note: Seastar previously specified MIL-PRF-5606H as an acceptable fluid for their steering but now specifies only their fluid ($28/quart at a national chain boating store). According to people who should know, the fluids are the same, save for the red dye that's added to the MIL-PRF-5606H fluids.

    Transaction was easy. Shipped quickly and well packaged. Product was exactly what I ordered. I will use and recommend PSC in the future.
