Grease Guns

Recommend one that doesn't leak all over the place

Mine only leaks when it is hanging on the wall. I have enough grease in it to last me for 20 years or 'US' for 10 years. Hint, hint, hint.

My understanding is that grease is essentially oil suspended in a soap or other filler base and over time tends to separate from that soap. Grease guns, as long as the spring loaded plunger keeps the grease under pressure force the oil out of suspension over time. So most grease guns are going to leak unless the plunger is released to relieve pressure.

Some greases are worse in this than others but absolutely one of the worst, although I still like/use it, is Amsoil's Racing Grease.

 

Other factors affecting this "oil sweating" are age of the grease, type and storage temperature.
