All good to know.
I think I have had the same can of MMO for 30 to 40 years. I think my grandfather gave it to me.
I did buy a new easy pour plastic bottle about 15 years ago because it had a cool looking bottle and was on sale. I don't think buying 1 quart in 30 years is going to break the bank.
5 gallons of mineral oil would probably last me 100 years. But thats just me.
Remember the teflon coating you could pour in your engine to make it last longer. I am mostly sure that was snake oil too but they convinced me to put some in my 1986 4 cyl Jeep. It still runs like a top and burns no oil.
