Sorry - no can do. Your tag probably looks something like this -

Label includes (since 1998 at least) the date of MANUFACTURE, but not installation date. Many installers mark the install date in felt tip pen on the tank end or above the label and/or on burner fuel pump (if it was put in at same time and has not been replaced), but not all and not required, so the actual install date could be a as much as years after manufacture date - possibly MUCH later if it was a used tank when it was installed.

Might also be on a maintenance tag on the furnace, showing tank install or replacement date.

If your area requires permits to install fuel tanks, if you go to your local building inspection and permits department and ask to see all the past permits for your house (have proof of residency like driver's license with address, some require something like a recent utility bill in your family name as proof of ownearship) it might be in there.

If it has an oil delivery company name on it, give them a call - ditto to your current/previous owner's oil provider, they might have account records showing when installed, especially if it belongs to them (if leased tank, as is commonly the case).

If in a state where oil storage tanks have to be state registered,, check with that agency - like NY Department of Environmental Conservation or CalEPA in California, for instance. If not real old should also have the state (if required) tank ID tag showing initial installation date, and dates of inspections with inspector ID number.
