Racing Dan, you are totally correct. I worked in underground mines with drifts in the 3 -4,000 foot below the surface where we dewater constantly and blasted everyday at mid shift, maximum water and where rock fragmentation is our business, and in smelters with constant blistering temperatures. We spent a lot of money on preventative maintenance products. Companies like Lubrication Engineers make greases for the hard rock mining industry that seal much better to prevent the entry of contaminants and are extremely tacky to help with water washout, but $$$. Nothing close to that severity exists in cycling even with the daily commute my daughters do in Portland, OR or I see on our desert roads. I have long ago given up logging milage so am out on a limb but empirically my $$$ tubs of grease I have offer little if any advantage in my or my daughters cycling or to the typical cyclist in anything near a routine PM program. That said, yes a 4 oz. tube of Park grease at 12 times the price per oz of the above shown Walmart special in an abused and neglected hub I expect is far superior.
