My father owned and operated two Gulf service stations in the 1950's-1970's. He saved numerous items from the stations.
I am currently cleaning out his large barn and we uncovered dozens of cases till sealed of Nitro 9 Marine & Diesel Additive as well as motorcycle additive. Most cases are still sealed and it looks like they have 24 & 48 metal cans per case depending on what type.
I also have cases of Gulf Valvetop Oil and Gulf Tri-Ad in metal cone top cans, presumably from the 1950's or 60's.
Was wondering if anyone had an idea of value?
I talked to someone with knowledge of the Nitro 9 and he told me it has no shelf life, so still good. Maybe someone who races or has hot rods with no catalytic converters?
Some help would be appreciated.
