Our "family boat" has a SeaStar hydraulic steering system, and after sitting all winter, the system needs to be bled [annually]. Well, this year, its time to buy another quart. The problems, in addition to costing $20/qt, is, there is no place to buy it locally. Their site lists a few alternatives [aviation fluids -- not like I can find them locally, either!] I'd hate to order online, and wait, and pay shipping. Can't I run out to NAPA and get something off the shelf?? Right??? Like what????
Thanks in advance,
jim

You would think something like automatic transmission fluid would work. Or even hydraulic jack oil for that matter.

Unfortunately, I dont have specs on the system, but its not high pressure, and not really any heat.
I DO THINK that hydraulic fluid of, well, any type, would be fine, but I'm no mechanic, and everything I've seen online from the manufacturer REQUIRES their product. On our small lake, its not like it could leave me stranded out too far if it ever failed...

If they only said how or why it was necessary, or, is it just for their profit?
