It probably can be done, but the way I attach the lid is just a single crimp. The originals were a double crimp and usually with a sealant applied on the edges to stop any leakage. One would have to unflatten the lip of the can which gets pressed down into the the lip of the lid to get a closed seal when it was originally lidded. If you have seen any quarts that have never been lidded you will notice that right angle lip at the top. I wouldn't want to get into handling oil to refill a can. It is bad enough draining full ones. I drain mine because of fire regulations, maximum of 5 gallons I believe are allowed in residences, plus a lot of sealed quarts start to leak on their own over the years. Also seen the results of a number of full quarts that have fallen from an upper shelf. Not a pretty sight! Cheers, Don.
