4 Pack Sewing Machine Oiler Oil Dispenser with Long Angled Spout Screw on Cap Extended Spout oil Bottle for DIY Craft, 120ml

They have a large capacity for spot oiling a sewing machine, so I only fill them about halfway. The large bottle gives plenty to hold on to, though, without being cumbersome. The caps seal tight and don't leak if they get knocked over - pretty good for thin sewing machine oil. The spouts are all metal and are not flexible. I prefer a rigid spout - I can be more accurate with it. The spout caps are also metal and screw on. This is much superior to plastic caps that always split eventually. Your only worry with these caps is losing one due to their small size - you are not likely to ruin one.

I got these to hold cutting oil for my drill press, but figured I'd use the extra bottles for other random garage things. I tried motor oil (works great), WD-40 (also works great), and brake parts cleaner (works, but evaporates slowly over time). I tried adding some rubber gaskets of my own to help with this, but the cap that screws on to the tip isn't a sealed surface, so no luck. That isn't what these are intended for, but would have been nice if I could have made it work. As for cutting oil, it's flawless. Minimal mess and just the right amount of oil dispensed. Can't complain for that use case.

really good

Great for oiling a Hammond organ and Leslie

These little bottles are awesome for oiling everything from light machinery to chainsaws. Easy to fill and easy to use.
