BAKLUCK Group I 40A Base Oil gives lubricant developers a property-led way to assess a 40A solvent-refined mineral base oil. Its source data shows kinematic viscosity at 40 °C of 51.28 cSt; separate entries for kinematic viscosity at 100 °C of 7.16 cSt and acid number of 0.022 mg KOH/g help distinguish it from lower- or higher-viscosity alternatives. The profile warrants investigation for circulating and enclosed-gear oil formulation studies, with industrial-lubricant trials requiring a medium-heavy Group I cut as an additional formulation possibility. Actual suitability depends on the additive package, base-stock blend, elastomers, operating temperatures and target standard. Compare laboratory results with the current BAKLUCK TDS, and use the batch COA—not these typical values—as the batch-specific commercial reference.
