What grease should be used for grease zerks?

[JamesLond]

I never really thought about it, but I've been using either EP moly grease or multi purpose lithium grease from O'Reilly's Masterpro brand.

The stuff's got a black color to it.

Not to be that wise-guy, but... Depends...

You can use high-temp grease in low-temp locations, but you can't use low-temp grease in a high-temp location.

I always went with a high quality red, high-temp like this one from Valvoline...

NGLI EP-2, 3percent moly Black. Do not use on white metals. Steels only. Thats why theres Red EP2.

Another great one, there. Have used on wheel bearings several times. Always stayed where it was supposed to.

Amsoil polymeric chassis grease, #2

IMO, ball joints should get something with moly in it. Low speed, high load, is a perfect use case for this stuff.

Also IMO, any grease is better than no grease. A dry joint will fail very quickly. I wouldn't get too hung up on it - just grease regularly and sleep easy. I do mine every oil change. ~half pump in each of the fittings. Too much is apt to blow out the dust seals, then you're worse off than you were if you never touched it.

I ended up using the masterpro multipurpose lubricant. On the tube it says NLGI-2 which looks to be the same as NLGI EP-2.
