Is Over Lubrication bad?

Post by ThePlinkster » 06 Feb 2021, 1:53 pm

Hey guys

Obviously

I know that excess oil/excess grease can damage wood
(And that that is to be avoided at all costs)
(And I do try to avoid that at all costs)

However

Can excess oil/excess grease damage rifles mechanically?

According to this interesting (pretty crazy) real life experiment/test:
https://youtu.be/p9bOT_d60LM
Excess grease/Excess oil does not seem to damage rifles mechanically at all

But what do you guys reckon?

Too much oil will be messy when it leaks out and attract dirt and combustion products to make a 'grinding paste' on moving parts. It will also give no additional lubrication or corrosion protection so it's best not to overdo the oil.

It won't cause damage directly though, even excess oil inside the barrel will be scoured out by the first projectile going through, its accuracy will suffer for it but that's all.

Yes to much oil can :-
1/ Pool under the action on top of bedding and affect accuracy .
2/ Leach into bedding and soften the material and delaminate it .
3/ Leach under bedding material and rot a wooden stock . The bedding can appear OK but under it is soft and no good .
4 Excess oil in the firing pin race can slow down the firing pin in very cold weather and have misfires . Gunk build up and oil can do the same .
5/ Excess oil in certain triggers can make them lighter and more dangerous .
6/ Excess oil on the outside metalwork can travel via barrel threads and insides of the action and leach down into bedding .
7/ Excess oil on the outside can make a gun too slippery and risk dropping it which could cause an AD .
8/ Oil in the chamber can allow the case to back up on the bolt face and put extra strain on the locking lugs because the case body is not gripping the chamber walls as it should . Cases can get dents also from pressure detonation of the oil .
9/ Excess oil in the bore of a high velocity round is very bad as it can cause the bullet to expand inside the bore causing a bulge in the barrel or worse .
That is why I never use oil on the outside , I use grease thinly applied with a short stiff brush and after oiling or greasing the barrel , I run a dental pad around inside the locking lug recess to soak up any excess oil that can pool there .

Go to Beretta pistol site look at most common problems
1 Lack of lubrication
2 to much lubrication
It just something you will learn in time

Go easy on your grease and oil. Here is what German Salazar has to say about bolt maintenance.

Thanks for your advices fellas...

The issue that I have personally myself is that my shotgun's action is very tight
It's very stiff
(It's a break open under & over shotgun)

And I just feel like I just have to spray quite a fair bit of G96 for its action to finally become somewhat smooth and for it to become somewhat workable
(I feel like I just have no choice because otherwise the action is just too stiff)

I was a little worried about "over lubricating" it with G96

However though

With that being said
Whilst I had a feeling that Over Lubrication wasn't ideal
I feel like G96 isn't as bad as standard oil/grease
As G96 is not a thick "gooey" substance or anything like that
So I think I might be right with the amount that I have used

A shotgun is different too the problems faced by a rifle .The tuning is not the same and oil will not affect it as much .
G96 is a thin lube and it penetrates more but it also runs off and dries up way quicker than grease . Use it inside the action but if you store your shotgun for long periods , nothing beats grease in the tube and on the outside . Most peoples concept of grease on a gun is a great lump of grease an inch thick . That's not what you do . Spread a very thin layer with a short bristle brush like a cut down shaving brush and you will be able to get into all the nooks and crannies and it stays put .

For long term storage some use wax based stuff.

Yes it dose a similar job to grease but costs more and is harder to find but can stay on and not need wiping off a bit before use like grease does . You can buy tubs of grease easily and cheap and the wax can't be applied inside the bore as grease can . Also to save money don't buy expensive pre cut patches go to Bunnings and buy a big roll of chux toweling and tear it into strips along the length of each segment . Then wrap it around a wrap style jag . You can adjust the length and width of the strip , pitch of the wrap for different calibers and tightness of the patch .

I have seen over lubricating ruin the pistol grip on an old shotgun.

Yep I have seen oil penetration rot out a wood stock under the bedding . The bedding looked fine but when I pressed it with a screw driver the bedding collapsed a bit .

I did a bit more research

And you guys were correct

As some of you have already mentioned

Over lubrication can in fact cause mechanical problems

Too much oil/grease/lubrication can cause grit, dust, carbon and powder residue to stick to it and that can gum up the insides of a gun, and that can be enough to make a gun stop shooting (Jams)

If you guys watched that video experiment that I showed youse at the start
In that video, it shows that over lubrication will not have an immediate short term negative impact on the gun mechanically
(Not right away anyway)
But in the long term
Over time
Once the grit, carbon, dust and powder residue start to build up sticking to the excess oil/grease/lubrication inside the gun
That's when it can start to become a mechanical problem
(The video experiment didn't show that, the video was a bit misleading as it didn't show the long term negative side effects of over lubrication)

Good to get to the bottom of it
:thumbsup:

In the Military I used Moly , Graphite mix , powder as an action lube instead of oil in dusty conditions . Worked pretty good .
Now they issue something similar . I have seen Police revolvers and pistols that were so dusty and dirty that you could not see through the barrel very well for fluff and dust . Some look after them very well and others don't . Revolvers can handle a lot more crap than an auto pistol .
