Mark, the M-1 product is a -new- lithium-based high-temp wheel bearing grease. It's a GL-2 rated grease, but lacks that 'long fiber' attribute that's often discussed around conventional wheel bearing greases.
For grins sometime when you have the kitchen to yourself, stick the candy thermometer in a little pot of your favorite grease and see where the slump fails as it gets warm. You'll be surprised at how little heat it takes.
When you tried the synthetic stuff and say that it was runny out of the cap, was there any left in the bearing cages? Roller bearing lubrication does actually depend on getting some warm flow from the lubricant to maintain a film on the roller faces. Point is that you can consider still having a stiff soap structure a failure at full temperature, since a stiff pack of grease isn't flowing to the roller faces. For those who still depend on that 20+yo grease in the front bearings, you can pull a cap cold and see if it looks like the old stuff hasn't been flowing in a while. Got a pink sort of cottage-cheese look to it? Time to replace.

It seemed to all just liquify and run out of the bearings. there was little left in the bearing area. I did this with amsoil grease too. I think it was just too runny. with the standard stuff, it gets thin under temp, but seems to leave a film over all the surfaces, and let me tell you, the mess with the synthetic was no fun cleaning up.

You know, this thread helped settle an argument I've been having with my wife this past week. It seems her trusty Mercedes parts guy sold her some moly grease for use in her front wheelbearings. I told her the regular red stuff I'd already used from the local store was fine, she said no I want the fancy stuff, I said I ain't cleaning out perfectly good grease from her bearings etc., back and forth, back and forth...
Then this thread comes along- PERFECT TIMING! I just showed her Mark's post. She says OK the bearings are fine the way they are.
I owe a you guys a beer!

I would LOVE to have a wife that would engage me in that kind of argument. But good on you for stomping her down with Rennlist tech

So the patholigist and the urologist were arguing over the dinner table... About the kids's sports schedules, right?
I don't wish for ANY arguments with K. If I ever want to be right about anything at all, that is.

Not "Why isn't that already fixed?" or "Didn't you just work on that?"

Here's the picture of my front wheel bearing that was run on moly grease fro less than 2000 miles. It was adjusted correctly. The other side which had LM grease in it was fine.

Don't know why the picture didn't show, but you can see it here:
