A new short fiber sodium soap grease having a high melting point is now being used in production in all front wheel bearings. This front wheel bearing lubricant has been carefully checked and tested under severe operating conditions and has proved unusually efficient. Under no circumstances should it be removed from new cars and other greases substituted.

The following are the specifications of this new lubricant:

Sodium Soap …………….. 15.0-17.0%

Free Fatty Acid (Cale as Oleic). 0.2% Max.

Free Alkali as NaOH ………. 0.3% Max.

Moisture ………………… 0.2% Max.

Mineral Oil. ……………… 82.3-85.0%

Viscosity of Mineral Oil at 100° F. to be 290-310 (Saybolt Universal) and to have nil acidity.

Consistency-Penetration of an unworked sample determined according to A. S. T. M. method D-217 shall be 175-200 at 77° F.
