The technical role of BAKLUCK Group I 20A Base Oil starts with its measured kinematic viscosity at 40 °C of 25.43 cSt. This solvent-refined mineral base oil also lists kinematic viscosity at 100 °C of 4.708 cSt and acid number of 0.016 mg KOH/g, creating a grade-specific basis for comparison rather than relying on the 20A designation alone. Potential development paths include hydraulic and light machinery-oil development and general-purpose industrial-lubricant blend studies, subject to the viscosity and performance targets of the finished lubricant. Laboratory work must verify additive compatibility, oxidation response, seal interactions and regulatory suitability. Treat every listed figure as typical reference data, and match the proposed batch to the current BAKLUCK TDS and COA during commercial qualification.
Group I 20A Base Oil
Within the solvent-refined Group I stock range, Group I 20A Base Oil is differentiated by 4.708 cSt 100 °C viscosity; that makes it a measured candidate for hydraulic and light machinery-oil development.

Frequently asked questions
Why might Group I 20A Base Oil be chosen over an adjacent grade?
The measured 4.708 cSt 100 °C viscosity separates this grade from lighter or heavier options and informs trials for hydraulic and light machinery-oil development.
Which documents apply to a commercial lot of Group I 20A Base Oil?
For Group I 20A Base Oil, request the latest TDS and the applicable BAKLUCK batch COA; confirm additive response, materials compatibility and finished-fluid results.
Final specifications are subject to the current TDS and batch COA.
