Mobil SHC™ 832 and 846 Ultra are superior high performance turbine oils designed for use in steam turbines, gas turbines, combined cycle gas turbine (CCGT) and turbo compressor applications under the most severe operating conditions.

Modern stationary gas turbines operate at high power output and severe operation causes thermal stressing of lubricant that can result in bearing deposits, filter plugging, servo-valve deposits and valve sticking or short oil life.  Mobil SHC 800 Ultra Series have been specifically formulated to provide exceptional protection against thermal/oxidative degradation and outstanding keep-clean performance with specific deposit and varnish control.

Mobil SHC 800 Ultra Series also feature the exceptional interfacial properties, in particular steam and water separation, required for modern high performance steam turbines. Mobil SHC 800 Ultra Series strong anti-wear performance is designed to meet load-carrying requirements of geared turbines.
