Gear oil for hydraulic and turbine systems

Miles Lubricants MSF1303005 is a synthetic gear oil with ISO Viscosity Grade 68 for hydraulic, turbine and circulation systems. It operates between -10 and 215 degrees Fahrenheit with a viscosity index of 112 and a flash point of 460 degrees Fahrenheit. The yellow fluid comes in a 25 lb bottle and carries no NSF rating.

Suits maintainers needing ISO 68 synthetic fluid

This product fits technicians servicing hydraulic, turbine and circulation equipment that requires ISO VG 68 synthetic base oil without additives. It is not for operators who need an NSF-rated lubricant, a different viscosity grade, or a fluid approved for food-processing machinery. Buyers requiring specific OEM approvals not listed here should verify compatibility first.

ISO Viscosity Grade 68 defines the application

The single specification that decides fitment is ISO Viscosity Grade 68, which matches the viscosity requirements of the target hydraulic, turbine and circulation systems. Using a different grade would alter film thickness and flow characteristics, risking equipment damage or inefficient operation. Confirm the equipment manual calls for ISO VG 68 before purchase.

Questions about this item

Will ISO VG 68 synthetic gear oil mix safely with the mineral oil already in my older circulation system?

The fluid is a synthetic base oil with no additives, so compatibility depends on the existing fluid; a full drain and flush is recommended before filling.

How can I confirm the oil is performing correctly once the system is running?

Monitor reservoir temperature to stay below the 215 °F maximum and verify the fluid remains clear and yellow without foaming.

What comes in the container and is any extra hardware needed for installation?

The 25 lb bottle contains only the yellow ISO VG 68 synthetic oil; no fittings, pumps or seals are included.
