Show Me Your Lube Shelf

[CoalCrackerAl]

My lube is a 75% synthetic motor oil 25% ATF. I keep a can of rem oil in my range bag.

"35mm film canister of Cotton Picker Spindle Grease"

Tell me about the uses for cotton picker grease... I have about a 1/4 of a 55 gallon drum under my shelter...

I have a needle oiler with free sample gun oil squeezings from foil packs. I can't remember the brand but its a light oil. Then a syringe oiler with Rotella 15-40 on the other extreme. I have a little bottle of Slip 2000 Synthetic that I save for special occasions, like when I strip and clean a AR15 bolt. I like Hornady One Shot for a spray lube and rust preventer. Moreso than RemOil. I'm convinced that the One Shot gun lube and Case Lube are the exact same product.

For grease I have a little tub of Slip 2000 EWG.

Boring lube drawer. I've used Redline and Mobil 1 oil, but then my guns smell like an internal combustion engine. Quit!

One thing I discovered by accident is that MPro7 and Mobil1 mixed approximately 50/50 makes, initially, a very thick oil. This thick oil (which I liked pretty well as a gun oil) has gradually continued to thicken to the point that it has turned to grease in the bottle in about four years. Also, during this period I have added more and more Mobil1 to the bottle, and it has still continued to thicken over time.

On the general topic of lubricants and mixing lubricants... for a few years I had a friend and business acquaintance who was one of the world's top authorities on lubricants and fuel additives (among other things, he ran Chevron's R&D labs when they invented Techron). He told me once that when you start mixing oils, such as engine oils (which all have their own additive packages) with off-the-shelf oil additive products, you have no idea what the result in the crankcase will be BECAUSE the additive packages can do funky things when mixed together. He strongly recommended against doing that kind of thing (putting additives into your engine oil). When I saw what happened when mixing the MPro7 and Mobil1, it brought to mind what my friend the lubricants expert had told me.

Follow-up on this. There's probably no useful information here for anyone else, but it's an account of what happened with the M-Pro 7 and Mobil 1 mixture.

The approximately 70/30 mix of Mobil 1 and M-Pro 7 (that's my estimate of the mix ratio that started out as 50/50, but I've since added more Mobil 1 due to continuing thickening) has now gotten so thick that it comes out of the nozzle on the bottle as an extrusion of grease. It has continued to thicken over time. I decided to thin it further with Mobil 1 and see what happened. Below are some related photos.

It got thicker and thicker towards the bottom of the bottle. It was so thick that you pretty much couldn't shake it up in the bottle. (For anyone who might possibly be familiar, it reminded me a little bit of the old cotton picker Spindle Lube that was used to grease the picker bars back in the day. I don't know if that lube is still used today or not, but it's thin grease somewhat the consistency of cake icing.)

NOTE that some Amazon reviews have claimed that the original M-Pro 7 product would thicken over time without anything being added to it (like I did when I added Mobil 1). With those reviews as reminders, I seem to recall that's why I added Mobil 1 in the first place -- the original product got too thick to use as an oil. Therefore, I'm not sure what role the mixing with Mobil 1 may have played in the thickening, but it's interesting to me that it continues to thicken over time even when diluted to about 70% Mobil 1.

I diluted the approximately 70/30 mix by adding a lot more Mobil 1, to the point that I believe the current ratio is about 88-90% Mobil 1. I would estimate the room temperature viscosity to be about 75 weight.

NOTE also that recent reviews indicate that the M-Pro 7 formula has recently been changed (someone said the company was sold) to the point that it is nothing similar to the old stuff like I had. Apparently it's now white-colored and it stinks like some offensive-smelling petroleum product (not the good-smelling ones).

Sorry this is probably a useless post.
