Opti-Lube Soda Block Grease (1 Carton of 11-12 Blocks) Approx. 48 lbs.

This is the #1 choice of steam railroad operations throughout North America. Customers frequently comment on reduced bearing surface wear, cooler operating temperatures and less grease consumption. Our block grease includes special wear reducing additives and is very hard (above NLGI-8), although it's still malleable enough to be pressed into grease sticks.
