This is a good deal, especially if you need more than 5 Qts. If you don't, you have some for top-off or the next change. There is a measuring window on side, so you have to do a little reading on the package.
Paper companies pay for used cardboard as it is easy and cheap to recycle, but it has to be clean (you can't recycle a greasy pizza box either). So if part of it gets oily, tear it off and recycle the rest.
Most plastic is not recycled, and oil jugs are at the bottom of the list as they have to be washed first. Too expensive versus new plastic so not economical.
Have a blessed day!
