So I just got a SW m&p BB gun. The manual says to lube the co2 cartridges with a drop of RWS chamber oil. The cheapskate in me with a $50 BB gun doesn’t want to spend $15 on a tiny tube that has to be shipped to me. Would either of these products work? Or should I just not be a cheapo?

I can't prove it but I suspect that Pellgun oil is in fact repackaged transmission fluid. In any case, I don't see why tranny fluid wouldn't work just fine. I, myself, use silicone oil or Secret Sauce because I have them handy but in a pinch I'm sure a lot of things would work.

One could look up the mos on pellgun oil. And compare to other stuff.
 
RWS chamber oil is non-petroleum oil (silicone based).

If you're going to use something else, use a silicone based oil.

Why? Well, we don't know what the seal(s) used in your airgun are made from and using a non-silicone based lubricant could be detrimental to them. The Lyman case lube you show in your picture is petroleum based, so don't use it.

Likely any number of other silicone lubricating oils will work. Spot On treadmill lubricant costs $15 for a 4 ounce bottle, for example. Super Lube food grade silicone oil runs about $7 for a 4 ounce bottle. Both available on Amazon.

A 1/2 ounce bottle will run you a long time, because you only need to apply a drop on the tip of the CO2 cartridge, where the seal will mate up to it. A 4 ounce bottle will last you MUCH longer.
 
Pellgun Oil is $15 now..!?
I found it for sale online from WalMart for under $3 a tube. Amazon has it for $4 a tube, but that's free shipping if you have Prime.

Seems like I get 4 or 5 years out of Crosman CO2 cartridge seals before they crumble. Other CO2 guns I have don't have seals that crumble, they just deform until they leak.

All this while using Pelgun oil. One drop for each cartridge and I don't leave cartridges in the guns.
 
Pellgun oil is just 30w motor oil - Monolec 8430 GFS to be precise - repackaged at an enormous markup.

Here's a link to the Pellgunoil SDS sheet:

As you can see, Crosman didn't go to the trouble of making their own SDS, they just provide the Monolec one.

I don't think the type of motor oil is particularly important.

My guess is that Crosman chose the Monolec product because it's red, which looks a bit more 'special' than regular motor oil.

I personally prefer to use Mobil 1 synthetic in my 2240, because synthetic oils are far less prone to gumming up.
