That grease is regular lithium soap wheel bearing grease - mobil had started to sell their tube cartridges of this grease, caltex, shell, PSO, FUCHS etc all carry this grease. Call around.
Grease is supposed to liquify slightly at the working temperature, if it remains stiff and the quantity is low - your part will sieze in very short time. Just like when this grease is in a wheel bearing - it actually moves through the bearing.
