WW2 Grease vs Post-WW2 Grease

[Rogue5]

Which is better to use on a Garand: The WW2 Lubriplate 130-A or the Dark Post-WW2 Grease?
Why did the military switch from one to the other?

[Smokey]

The later grease is "Plastilube" which might resist washout from water/rain better than "Lubriplate".
I use Mobil 1 Synthetic grease, but any decent automotive chassis grease will do a fine job on a Garand.

When did the military switch over from Lubriplate to Plastilube?

[Smokey]

I think the plastilube may have started being used after WWII.

Try Lucas Red "N" Tacky grease. As a modern grease it is more than adequate for the Garand

[Smokey]

I use Mobil1 Synthetic chassis grease. In practice any decent automotive chassis grease will do a fine job. What is important is to grease EVERY location shown below, including the "optional" ones:
