i was looking at an older tin can Coles gun grease that I have for a while and was wondering if I could find something equal to if off a shelf locally. It’s blue in color and was thinking some sort of marine grease possibly.
I picked up some different ones and tried them for a while to see if any compared to the CG grease. My testing was done by sight and feel alone. Nothing scientificky about it. Used on an OU pivot areas.
Coles went in and stayed put but after 150-200 rounds felt like it was in need of a re greasing.
Stp marine grease was one prettiest in color I tested but lacking in stiction. After about 100 rounds it felt like it needed more. And when I disassembled the OU you could tell that it was much thinner and not Much left where I put it.
The best one Ive tested so far was the Lucas marine. Kinda blue/greensih in color. It felt like it was still there after 300-400 rounds. The gun still opened and closed smoothly And when I took it apart there was quite a bit still on the pivots.
I put some on a card after testing to contrast the colors and was kinda surprised by the oil “creep”. oddly or not the creeping aligns with what I found out in the prior weeks. Lucas stayed put followed by Cole’s and then the STP.
1st pic was at the time of applying it to the card.

I’ved switched to using the Lucas marine grease where needed and Lucas gun oil where needed. Going to run that a while and see how it goes.
Again not scientific. YMMV. My observations only. Just thought I’d share.
