I did a complete restore of the SLS after it was removed by the previous owner, been running ISO 46 hydraulic oil from Tractor Supply in it for 2 years now with no issues. SLS gets a good workout since I pull my boat with it. I don't know if it'll mix well with whatever fluid was originally used since I started with a new, dry system.
