Picked up a Crosman 1377 pellet pistol a few months ago. Couldn't get the Crosman recommended Pellgun Oil anyplace . Gotta do some oiling after the first 250 shots and it's getting there soon. Poked around on the web and some folks say they use Kobalt air tool oil, available at Lowes. They claim it does the same thing and is also beneficial for seals. So I picked up an 8oz. bottle for a little over four bucks. Label says it's for all oil lubricated pneumatic tools. Now that I bought this I see some places now have Pellgun oil back in stock. Should I just use the Kobalt stuff I already have? Anyone have any experience with it? Just curious; here's the Kobalt :.. IMG_2110.JPG
 
I have been using RWS silicone chamber oil in my Daisy pump guns and they really seem to like it. Also the long oil needle is nice to get in tight spots and put the oil Right where you want it and get very controlled number of drops.
Having said that, the current street price is $15 for a small bottle, I have heard that 30w non detergent motor oil is Really good for pump guns and a quart is pretty much a lifetime supply. I am going to try it and see if it's as good as my chamber oil.

I thought so too. It turns out that the MSDS supplied by Crosman says Pellgunoil is 8430 Monolec GFS engine oil- which is a straight weight SAE 30 motor oil distributed by Lubrication Engineers, Inc. It’s interesting that this oil is described twice in the MSDS as having “detergency”.
 
I've never use pellgun oil. I use 20w oil over 40 years never had any trouble..Please dont put to much oil on your seals this will also destroy your Air Guns..Keep Your Barrel CLEAN
 
I'd like to thank everyone for all the input. Probably gonna just use the air tool oil I already have. Sure won't use any 3 in 1 oil or other type stuff. I also have a .22 cal. Benjamin Trail rifle with the Nitro Piston gas system. That one calls for Crosman silicone chamber oil that I already have here. Too bad I can't use that in the Crosman 1377 but they specifically call for Pellgun oil. Good to know that there's a lot of suitable substitutes out there. Few months ago that Pellgun oil seemed to be out of stock every place I looked.
 
Mac1air sells secret sauce for $10 a bottle. Should last a long, long time. Great for pneumatic pump guns.
 
Really any light weight motor oil is fine.
As is mineral oil.
Your be shocked at what everyday stuff is repackaged,a new name tossed on it and sold for huge mark ups.
Look at Coleman fluid for stoves and lanterns...in reality it's just unleaded gas for $12 a gallon.
Gas line treatment?....non colored kerosene at about $3 a half pint that's pretty expensive kerosene...makes it $72 a gallon.
 
The generic substitute for pneumatic pump guns is 30wt non detergent oil. Crosman has the sds on what they uses, and of I recall right, the brand is monolec.

Tim McMurray at Mac 1 air is a 3rd (what I've read) generation airgunsmith. His secret sauce is a repackaged oil that he's extensively tested with great results. I guess pellgun oil gets crusty over the years and can be tough to clean out.

I guess the big thing with pneumatic pump guns is that you want to keep them well oiled, not just for the seals and wear resistance, but it's also a part of keeping it clean on the inside. Flushes out contaminants as long as you are using them a bunch.

No that is not true. Camp stove fuel is NOT unleaded gas. The whole BS of the old AMOCO white gas is not correct. White gas is not the same as gas for a car.

https://pimproductmanuals.coleman.com/documents/ColemanAU/Camp-Fuel.pdf
 
I remember reading about some speculating Mac 1 Secret Sauce is repackaged compressor oil. There is no charge for this wonderful information.
 
A search of the interweb, shows so many hits on Pellgun oil and it never seems that it has ever been establish if it is indeed any different than some other oil. ATF or Snake oil?

Guess is is another Marvel Mystery Oil!?

On the other off topic. generic camp stove fuel( aka white gas) can be used instead of Coleman brand, but it is not non leaded gasoline!

Now onto what is the best gun lube!:eek:
 
Pellgun Oil is supposedly LE Monolec

Not sure what brand, but secret sauce blurb....

"Secret Sauce is an AW (Antiwear) class 30 weight Hydraulic lubricant that has been tested extensively by Mac1. It all but eliminates wear in single & Multi-Stroke Pnuematics and can also be used on pivots of springer systems. NOT suggested as a chamber or spring lubricant for spring or ram powered Airguns."

It's $10 for a 6oz bottle. That's a lot od oil for a long time.

I have Crosman Legacy 1000 and Pellgun oil definitely restores pressures. I shoot mostly BBs and with 4-5 pumps, I am shooting essentially flat at 25-35 yards punching through soup/tomato cans.

Here is a chance for you to take on another "project" !:)

Determine exactly what PellGun oil is? and what can be substituted. Is it just some 30W oil??
Are there any real chemistry tests out there on the web./ I can't find one that has any proof.

Well, I am a BioChem major drop out who eagerly wanted to join the Army (Did finish college after my stint) but I did get all A's during college years (Chemistry, Calculus, Physics, Biology, Psychology, Computer Science CompTIA A+, etc.)

When I was going through physical therapy for my back and couldn't go shooting, I bought several pellet rifles to shoot on our property. I managed to get around 1" groups at 25 yards and sub 2" groups at 50 yards.

I did look into alternatives to Pellgun oil and on various airgun forums, silicone oil was suggested and I bought a bottle from local Home Depot. I would say if you had nothing else to use, silicone oil would be an "OK" temporary solution but it is thinner than thicker Pellgun oil which does a MUCH BETTER job of sealing to produce pressure.

This is interesting as Pellgun oil is the same red color as ATF without the odor and in recent years, AFAIK have been silicone based.

If you think about it, automatic transmissions have A LOT of O-rings and seals and I would not hesitate to use if I couldn't get Pellgun oil.

The myths must be verified.:)

What's interesting is the application. Consider that OP is using a multi-pump pneumatic air pistol

And Pellgun oil states:

"For use with CO2 and pneumatic airgun
seals, moving parts and pump action.

CAUTION: Petroleum based oil
Not for use with break barrel or
Pre-charged pneumatic (PCP) airguns"
​
So for higher pressure break barrel and PCP airguns, use of flammable oil can "diesel" (Ignite under pressure boosting pressure) so use of non/less flammable oil like silicone is recommended. BTW, MSDS for silicone oil - https://www.finarchemicals.com/msds/silicon oil.pdf

But for OP's application of Crosman air pistol and my Crosman BB/pellet rifle, "dieseling" is not a concern due to lower pressure and design and could use different oils as long as they don't break down the seal.

And here's MSDS for Pellgun oil from Crosman website - https://help.crosman.com/material-safety-data-sheets

Pellgun oil MSDS - https://f.hubspotusercontent00.net/hubfs/8151552/msds/SDS-PELLGUNOIL.pdf

MSDS states Pellgun oil is Monolec® GFS Engine Oil 8430 -
https://products.lelubricants.com/v...hts-sae-30/monolec-gfs-engine-oil-8420-8450-2

"Lubrication Engineers' Monolec® GFS Engine Oils are a family of SAE 20W through 50 straight-grade engine oils formulated for extended drain service in on-road, off-road and marine diesel engines."​
