Gulf - Yes, have been using Mobil 1 5W30 for many years (10 at least) on all semiauto pistols and shotguns. Lifetime supply for $5. Works great with no downside that I can determine. Still use CLP on AR, however. Just habit, I guess.
You're not crazy, it's a fair question. I have been told by several that the Mobil 1 product is equal to if not superior to other traditional gun lubricants. Just curious about the experiences others have had using it.
I have often wondered if some vendors just rebottled motor oil and sold it as their own brand/formula gun lubricant. I'm not saying there is anything wrong that, but it would seem to be a great way to make money.
If Mobile 1 was so great on firearms, the US Military would
use it. They don't!. They use Militec was which was originally formulated
for use on the Gatling gun. To my knowledge, no testing lab has tested
Mobile 1 on firearms. The FBI lubricate tests indicated that FP-10 was
superior to other luricants tested. They did not include Mobile 1 in
Miltec means nothing except it was spec. Started out as a private here and moved up- undergrad engineering degree, so not without some information here- so forget that logic about miltec- it might be speced for varying conditions but always automatic rifle firing
The oil tested in that one report I cited was straight 30 weight- I know wolfheads has been used for racing but dont know if it is a synthetic or what
Next someone asked about repackaged used oil- funny you asked- I mentioned using STP to a very well known shooter- next thing I know he buys a 55 gallon drum of the stuff and mixes it with some lighter oil and sells it in these little applicator bottles
Now shotgun lubrication for over and under or signle barrel trap guns is not rocket science- you want something that will adhere in all weather conditions and is slick. I also believe that the oil can float the parts and even out possibly an uneven surface to surface distance along the bearing line
Finally- try some- if you dont believe - just dab some mobile one or some stp on your bearing surfaces
I will guarantee I have done the trick with stiff brownings at gun clubs around the country== a bottle of stp will last for years and mobile one for longer
BTW there was a company that did nothing but lubrication research for additives(99 percent car and truck oil additives) that employed in its heyday several hundred people= right around from where I lived in Ohio- check it out- I think the name is Lubrizol
One small thing to remember your car has a system that keeps the oil circulating so there is fresh oil always being applied. Your shotgun does not. The hi viscosity oil MAY stay in place or it MAY NOT. Firearms specific gun oils usually leave a film of some type (teflon or such)that MAY or MAY not keep the joint lubed after the oil is gone. So I use grease on any metal to metal moving contact points and RIG on anything else to prevent rust.
I use Mobil 1 5w20 and Mobil 1 synthetic wheel bearing grease on my Browning. It gives excellent results. As for gun oil I think you could pizz in a bottle of sewing machine oil and give it a catchy name and sell it to gun owners as the greatest lube ever. It would sell like hotcakes.
Us fisherman also use Rocket fuel to clean our reels and lube bearings.Great stuff,bearing hand spun will run several minutes just sitting on table after treatment.I doubt you could use it on a gun though.It is flammable. LMAO
JFYI, when it comes to lube used in the military, there was a time that you used what they issued to you. In Iraq, individual units would purchase whatever they were convinced was the thing to use. There was also a warning letter distributed, that warned against purchasing certain cleverly named , so-called "milspec" lubes.
There were more salesmen in Iraq that there were terrorists.
MK19's need a specific lubricant, but the majority of military weapons will work with just about anything.
