I needed to find a way to put oil into my transmission and differential which I had just drained for service. Squeezing the bottle was not an option. So I came up with this. I turned my compressor regulator down to about 3 PSI. It seemed so little I probably could have blown on a piece of hose and produced as much pressure.
I drilled a hole at the top of a bottle of oil. Cut the lid off square at an ID just smaller than the vinyl tubing I purchased. I then forced the tubing through the lid so that would make a seal. I trimmed the bottom of the tubing so it couldn't get plugged on the bottom of the bottle. I then used a rubber tipped air Chuck to pressurize the bottle once I had the end of the 2-foot tubing in the fill hole for the trans or differential. It works like a champ. Refill the bottle and pump another quart in.

I just filled my diff and trans with re-tasked garden sprayers from Home Depot - one for each type of fluid. Took the spray nozzles off, keeping the wand / triggers on the hoses. Made filling both quite easy!
I have a hand pump that accomplishes the same thing, but that’s a really creative idea! Certainly one step easier then even a hand pump. Nice!

Both great ideas. I even have an aluminum pump but the openings on it are pretty small for driving 75 140 gear oil. I was trying to make this happen with stuff I already had at the shop.
The only thing is that you have to be careful and make sure the compressor has a water absorb filter on it.
It's only displacing about a quart or 2 of air so I am thinking this wouldn't be an issue. Now if your air hose is shooting water you have other problems.
would any plastic chips from drilling the hole and falling in the bottle be an issue?
In my case with a sharp drill the chips were strings that came out, not in. I also continued using the same bottle and just refilled it each time. Could have drilled the hole a little higher if I'd really thought about it. Was worried about pushing through and hitting the inside when it passed through so I added a little safety margin on that by drilling lower, but didn't really have to.
(edit)
And no, a tiny piece of plastic isn't gonna do anything in there even if some were to get in.
I was using this technique in 1964 when striking down 55 gallon drums of 2190 tep to the main engine reduction gears aboard a navy oiler. Nice to know it still works.

When doing gear oil I'll throw a small 1 gallon bucket of water in the shop microwave for 8 to 10 minutes and get the water good and hot. Then I put the gear oil bottle or bottles into the bucket for 5 to 10 minutes....makes it super easy to pump and flows great. Very important if you have an unheated shop!!

Transmission and differential oil-fill trick
I bought the Amsoil one which works really well.
