During extensive testing, the oils – in viscosity grades 32, 46 and 68 – demonstrated the ability to deliver a high degree of protection against wear, rust and corrosion, even under extended drain interval periods.  

In addition, results showed how the oils can maintain compressor cleanliness by helping to minimise sludge, varnish and deposit formation, which can occur when compressors operate in extreme load and temperature conditions. 

“Mobil SHC Rarus Series synthetic oils are uniquely capable of helping companies to maximise the productivity of their equipment and generate valuable benefits such as reduced oil usage and disposal up to 67% when tripling the oil drain interval versus other synthetic compressor lubricants,” said Rainer Lange, Mobil SHC brand advisor, EAME, ExxonMobil Fuels & Lubricants.
