What Pump Do Y'all Use?

After my recent fiasco with changing my diff fluid, I figured it's time to figure out a better solution than the cheaply made auto store hand pumps. I know that there are some drill powered pumps out there but the ones I've found are all meant for garden hoses and water so I worry about the pump's ability to handle thick gear oil. The other kind that I've seen are these syringe style ones which seem like they would work fine, although may be a messier due to limited capacity and having to take the hose out of the diff multiple times. Wondering what some of y'all use for these kinds of jobs.

I used one like this last time. It worked ok. Nothing special. A little cumbersome to keep the hose in the hole, but not bad.

Valvoline's flex fill packaging works really well. Looks like Amsoil has started using it too.

Only reason I haven't been using those is because every time I would read gear oil threads (albeit most fairly old) they seemed to be against synthetic gear oils. Have I been drinking the Kool-Aid on that?

Yep. Internet legend. Use whatever you like unless your repairs are under warranty and then use whatever they tell you to use.

I've been seeing a bunch of meme(?) content around using those long tube-style squirt guns to suck the oil out of the container and then shoot it into the diff. Haven't tried but it seems like it could work. The transfer pumps...the Harbor Freight one anyway....seems to be single-use. I've never had one work after sitting on a shelf past the initial use. The squirt gun trick would be cheaper if it actually works.

One of the points of me asking (which I didn't make clear, whoops) was that I wanted to see if there was a less strenuous way to get the job done. Those work, but anything that saves my arms would be better.
I hear THAT noise - pumping those things is strenuous work!

Ok, hit me! I'm giving away freebies today! :ROFLMAO::ROFLMAO:

I've seen those too, was sent a few by my friends when I brought up this issue a couple of weeks ago. I think my only issue is that I'd still prefer to have a hose on the end that goes into the diff for hard to reach angles/obstructions and to reach inside the oil bottle. From the one's I looked at when mildly considering it, It seems that there isn't a great way to attach one, but I've got nothing but time right now so who knows what I'll find.
