That's not DTE Light. That's "DTE 24 Hydraulic Oil". The stuff recommended for turbines is "DTE LIGHT Circulating Oil".

It gets confusing because Mobil uses the terms Light, Medium, and Heavy to indicate viscosity ranges for a number of their products.

Click on the following to see Mobil's Product Data Sheets:

"DTE 24" is one of their DTE 20 Series Hydraulic Oils, which is recommended for hydraulic equipment:

"DTE Light" is one of their DTE Named Series Circulating Oils, which is recommended for turbine applications:

The specs are similar and the hydraulic oil may work, but I'm looking for the stuff that's recommended for turbine applications. I'll have to check with McMaster-Carr since they are the only ones that show it available in gallon jugs.
