I bought one of these large syringes, and use it for everything. I suck oil from mowers, gas from small tanks, and I use it to refill gear cases, etc. It comes apart and I clean it with brake cleaner if I need to. It’s called the:
Mityvac MVA6851 Fluid Extractor

I’m kind a bias as far as my bottle goes but I
have the extractor in my eBay watched items.
Putting in gear oil was always a pain.
I was thinking I could put a hole for hose in
the cap of a gear oil bottle. If I put the hose
all the way to the bottom I could push the oil
out. I don’t mess with cars much anymore but
I’m going to try it on a gear case. Could be
another good idea that ends up in the dumpster.
If it does I’ll have one of those before its time
to change the gear oil in the motors I run this
year. Thanks for posting.
