Hehehehe... somehow I thought that might be the case. You see, I cannot believe any bicycle parts manufacturer (except maybe Shimano and Campy) will put research and development dollars into a "special bicycle grease", especially when the grease is already being produced for other, non-bicycling applications.

It's just like many other moving, non-fashion/trendy parts on a bike -- the bits are sourced from companies that (a) specialise in producing those things such as bearings and (b) have the economics of scale to supply those at the cheap prices the bike makers want.

It's only when you go to a bearing wholesaler/retailer with a serial number and they say: "Yeah, we've got 'em in stock" that you realise all this. Even more sobering when you realise the same bearings are used in wheelchairs!

But the keys in the quoted bit from Mobil are: "specifically to enhance the performance of..." and "operating at high temperatures".

"Enhance" to me means improve over using ordinary lubricants, and likely means increase longevity; high temps puts us back with the front bearings on the Mercedes Benz

On another forum (a long-distance one, or it might have even been here), a guy who had been in the lubricants industry for many years posted something along the lines that the only differentiation between oils (grease wasn't the specific issue at that time) was in the additives. He concluded by saying he used synthetic motor oil on his chains. Sorta blew the "use bike lubricants only for bikes" idea out of the water.
