Product overview

BAKLUCK Group III 250N Base Oil occupies a distinct 250N position within the hydrocracked mineral base oil range. A reported density at 15.6 °C of 0.841 g/cm³ by ASTM D1298 provides one reported property reference, with kinematic viscosity at 100 °C of 7.36 mm²/s by ASTM D445 and kinematic viscosity at 40 °C of 45.81 mm²/s by ASTM D445 showing how the grade behaves in other selection dimensions. Formulators can investigate it for mid-viscosity Group III engine-lubricant studies, or compare it with neighboring grades during industrial-formula trials needing a higher-viscosity Group III component. Evaluation should include additive treat response, low- and high-temperature performance, materials compatibility and the intended finished oil standard. Use the values as an initial technical screen and request the current BAKLUCK TDS plus the applicable batch COA before approving supply.

Frequently asked questions

Which formulation trials suit the viscosity of Group III 250N Base Oil?

The 7.36 mm²/s 100 °C viscosity entry places the grade in a useful range for mid-viscosity Group III engine-lubricant studies. Treat that as a screening direction, not an approval claim.

What should a formulator request for Group III 250N Base Oil?

For Group III 250N Base Oil, ask BAKLUCK for current technical data and the relevant COA, and state the finished-fluid specification and test program.

Final specifications are subject to the current TDS and batch COA.
