Walmart has Shell Rotella grease and gear oil now. Seems interesting the brand name is enlarging from diesel service (LongLife coolant and of course the oil) to something that anyone (with a zerk) would use.
Shell's Rotella website http://www.rotella.com/ makes no mention of this product. Strange, but I guess it isn't strange that once again website information maintenance is one of the last things they are getting around to!
