I have an opposite opinion on the M/B green synthetic grease. I don't like the stuff. It is a high temp/pressure lube, maybe too much so. I've seen plenty of low mileage wheel bearing failures with it and I attribute it to the green grease not "flowing" as mentioned earlier. It stays sorta waxy and once pushed out of the path of the bearing it doesn't "melt" enough to flow back into the bearings. The result is that the bearings essentially run dry despite grease being in very close proximity. I prefer good non-synthetic grease that will "flow" once the bearings are up to temperature.
