Specifically oil specs for the power steering gear housing and power steering reservoir. According to the specs the power steering gear housing calls for ESEN-M2C94-BA, ESW-M2C28-BA or M-4864-B and the power steering reservoir calls for ESEN-M2C92-A or M2C41. From what I have been able to find ESEN-M2C92-A (power steering reservoir) is a 10W-30 hydraulic fluid and I think I have found a few sources for fluids that meet that spec, including Pennzoil. Any additional info. on this spec would be helpful. The bigger problem is power steering gear housing (ESEN-MC28-BA), I haven't been able to find a fluid that meets that spec or what sort of properties this oil is. I think it might be a 90 weight gear oil, but I'm not sure. Any help would be appreciated. Edit: I meant to post this in the hydraulic fluid board.
