Liqui Moly Hypoid Gear Oil (GL5) SAE 140

Worth knowing

The name and the table in the data sheet give different grades. The title of the Liqui Moly document says SAE 140, the description says SAE 140W, and the SAE J306 grade line says 85W-140. Below that comes the Brookfield viscosity: not more than 150,000 mPa·s at -12 °C, which is the limit of the 85W grade under SAE J306. The figure of 27.7 mm²/s at 100 °C lies within the range of grade 140, so the discrepancy concerns the cold limit. The data sheet asks you to follow the viscosity grade set by the unit’s manufacturer, so if a seasonal SAE 140 is specifically required, this line is worth confirming with Liqui Moly.

The table of figures otherwise matches Hypoid Gear Oil (GL5) SAE 85W-140: 375 mm²/s at 40 °C, viscosity index 100, pour point -24 °C, sulphated ash 0.09 %. The codes are where they differ. Here the specification block has only API GL-5 and MIL-L-2105D; there, ZF TE-ML 16D and ZF TE-ML 21A with ZF number ZF005974 are added. The ZF entry exists only in the neighbouring data sheet, and matching figures do not carry an approval across.
