there is definitely a demand for this!I took 6 cases of NOS metal wolfs head quarts to the Hershey car show this past yr and didn't sell a single one to a petro collector. @ $9/$10 a piece the old car guys gobbled most of them up and every single one of them wanted to use the actual oil in their car. The funny thing is I couldn't give away nice old metal Esso quarts- everyone called it junk oil! I guess it all comes down to zinc content?
