Selection of BAKLUCK Group I 120 Bright Stock can be grounded in three visible source-table entries: kinematic viscosity at 100 °C of >20 mm²/s by ASTM D445; viscosity index of 85 by ASTM D2270; and coking tendency, maximum of 0.5 %. They define a specific 120 Bright Stock profile within this solvent-refined mineral base oil family and help separate the grade from nearby alternatives. Likely screening work includes grease and heavy gear-oil base-blend studies, while viscosity-building trials in high-load industrial lubricants offer another technically relevant formulation path. These are screening directions, not certifications or finished-fluid guarantees. Run full formulation, compatibility and performance testing for the intended service, and check the current BAKLUCK TDS and batch-specific COA before committing to production.
