Shell Gas Compressor Oil S4 PV has been specially developed as a versatile cylinder lubricant for reciprocating compressors handling a range of hydrocarbon and other gases. It is based on polyalkylene glycol base fluids and is fully approved by leading gas compressor manufacturers.
Shell Gas Compressor Oil S4 PV has reduced hydrocarbon gas solubility to provide reduced viscosity loss in comparison with mineral oil-based products, improving piston ring and packing lubrication and helping to extend
service intervals, reducing maintenance and downtime costs.
The low hydrocarbon gas solubility and associated low viscosity loss results in retention of a stronger lubricant film
on the cylinder wall, piston rings and packing components, delivering low levels of corrosion and cylinder wear.
Lower cylinder feed rates are possible compared to conventional oil due to the higher levels of wear protection
and lubrication provided improving reliability and reducing the oil carryover into the compressed gas.
