How often does everyone change the fluid out and who uses regular ISO 32 vs the Green Marine biodegradable stuff? The reason I ask is I had a cracked hydraulic line (failed sitting in my driveway covered up) and decided to flush my system. After watching video's of all the sludge in peoples reservoir's it made me question the recommended hydraulic fluid. JL Marine is awesome and sent me everything I needed to repair mine free of charge but I'm not sure if I want to use the Green Marine fluid again. My Blade worked fine other than the blue hose cracking in the driveway. The reservoir was full of sludge and the two screens were just about plugged from the sludge when I pulled it apart. I have never lost or added any fluid and no water intrusion unless its through the vent on the cap (humidity) when the pump is running. After watching videos it seems like this might be a common problem. Curious how many here have actually pulled the reservoir off and seen the same sludge issue.

I have always checked my level and greased the bushing thinking that was enough. If I do go back with the biodegradable stuff I will just change the fluid out every year. It must be the price you pay to be environmental friendly.
This is after some cleanup. The new screens and O ring are on the way thanks to JL Marine.

I decided to go with ISO 32 this time and see what it looks like after one year of use. I will definitely change the fluid every year now that I know better.
