I used to use it in my IPSC competing days.
A heavy training session involved 500-600 through my 2011.
Most gun lubes would cook off and dry halfway.
Since I had discovered Mobil-1 synthetic 5W30, a decent amount (as in not overlubed) would keep the gun wet for the entire session.
Was incredibly dirty afterwards.
But did the job quite well, shot a certain 2011 in the 70,000 round count and remained tight until the day I sold it doing this.
And that my friends... is what I like to call the 'definite answer'...thread ender LoL.
Thanks BTW
