I’ve been experimenting with different lubricants for a year now because a lot of the firearm “oils” are 99% marketing and 1% oil at a premium price. You’ll notice that how to lube a firearm is a religious argument for many and I’m not going to get into that.
After doing a lot of digging, I bought two different types of automatic transmission fluid (ATF) (Dexron III and ATF+4) and Mobile 1 Full Synthetic 5W-30 engine oil. I then loaded up a bunch of squeeze bottles that have needle dispensers on them, labeled each and proceeded to try them out.
Here’s the big secret – they all work. Of the three, I like the Mobil 1 mainly because it doesn’t have a red color or the smell of transmission fluid.
I’ve now used it to lubricate my AKs, RPK, Uzi, POF-5/MP5 and PTR PDW and am very happy with the results. It works just fine and a quart will last you forever.
I still prefer Tetra Grease where sliding parts are involved. As the old saying goes, “if it rotates then oil it. If it slides, then grease it” has always worked for me though I do admit to reading armorer manuals to see their recommended lube points.

The Right Dispensers Make a Huge Difference!
Regardless of the oil you use, having the right dispenser really helps. Growing up, we used engine oil out of the tried and true cans with the finger squeeze pumps. I really don’t use that type of dispenser on firearms but do when I work on cars and what not where a large volume is needed.
With firearms, you’ll notice that you often need to get the right lube to the right place. In the shop, I use the squeeze bottles. The dispenser pens are something I take in the field as they don’t leak and will not make a huge mess if crushed — let me assure you the bottles will do just that so that is why they stay in the shop.
You can get both of these dispensers very easily off Amazon. Be sure to read reviews as some brands leak and others don’t. The ones I am listing next are what I currently use. I use the 25 gauge needle especially for reaching down into fire control groups and lubricating pins and their attached parts such as triggers, hammers, selectors, etc.
