Hacaroa3 Pack Plastic Engine Oil Jugs with Lid, 1 Gallon F-style Storage Container with Ergonomic Handle, Black Empty HDPE Bottle Jug for Motor Oil, Bleach, Detergent, Lubricant

I wish I would have bought these many years ago. Make fluid exchanges so much easier. I don't have to wrestle with empty containers constantly. You only really needs 3 to have enough container buffers space if you will, but so worth the purchase.

Used one to ship back a faulty container's worth of content for return to FCP Euro. I filled it up, tightened it and did the dip test with no issues with leaking.

Good quality and good price.

I would like if it had graduation marks indicating capacity.

Spare waste oil jugs. Yeah, no markings to know how much, but you can do that manually.

Great Value

They are cheap. They held oil (granted I didnt try flipping them upside down or really moving them much at all once filled). They're easy to transport.On the downside, the material is thin. It's stamped for a suitable plastic but the quality just doesnt align. I wouldnt use for long-term storage but they're good for a quick fluid change.

Got these to store nutrient solution for semi-hydroponics. The opaque plastic is good for preventing algae growth in the container. There's a translucent stripe at the front showing how much is left in the container—I just store these jugs with this side against the wall.I'm disappointed to see that the lids are not child resistant at all despite being advertised as such. They're just normal screw-on caps but with the tamper-evident bands still attached—they don't make for very good tamper-evident bands as they stay stuck to the lids.
