Fluids / SAE 30 mineral oil

Thermal conductivity of SAE 30 mineral oil at 40 °C

A single published state at 40 °C. This library carries no temperature curve for SAE 30 mineral oil, so there is one value here rather than a chart — showing a flat line across a range nobody measured would suggest a constancy the data does not claim.

Treat this as a room-temperature figure and nothing more. Every property here moves with temperature in reality; this library simply has no table for how.
