The refined oil that makes up most of every lubricant — typically 70–90% by volume, the base additives are blended into.
API Group I to V, in solvent-neutral cuts — from solvent-refined Group I to true synthetics (PAO, esters).
Its quality — how well it resists heat, oxidation and thickening — sets the ceiling for the lubricant made from it. Classified into API Groups, with higher groups commanding a premium for cleaner, longer-life oils.
Quoted as SN 150, SN 500, Bright Stock, with viscosity index, pour point, flash point and sulphur the key quality markers.
Key applications
Petroleum ProductsAutomotive lubricants
engine oils, transmission and gear oils.
Industrial lubricants
hydraulic, turbine, compressor and circulating
Engine, transmission and gear oils — the fluid base of finished lubricants.
Hydraulic, turbine, compressor, transformer and metalworking fluids.
API Group I–V, from solvent-refined to true synthetic — Group II hydrotreated is mainstream; Group III high-VI markets as synthetic; PAO and esters for demanding duty.
