Mobile One Grease Melting?

[ScottL4619]

I have a tube of Mobile One grease that I use on my front end zerks. I leave it in the grease gun between uses. I was cleaning the garage and noticed that the gun is leaking liquid grease all over the place. It isn't that hot in there.

Is this common or possible a bad tube of grease? It's only a year old. I would think the pockets that hold the grease underneath my truck would get at least as hot, if not hotter. So does that mean the grease in my front end is also turning into liquid and dripping out around the rubber boots?

its not melting bud its just separating.. its like a ketchup bottle... but it is kinda hard to shake a tube of grease... wrap a rag around ur gun... thats what we do on the shop at the bowlin alley
