oil can collectors here?

I've come into a bunch of cardboard oil "cans" that I'd like to display in a vintage service station display rack.
My cans are still full. Does empty or full have much bearing on collectible value? I'd like to use the oil.

 

That depends on what each collector wants. What do you want?

 

First of all, I wouldn't expect much from any additives left intact in that oil. The molecular consistency of the oil itself would have to be subjected to laboratory tests, unless you're using it in an old lawnmower.
If the collector wanted the can empty, he has the option of emptying it himself. If the can isn't opened with one of those vintage triangular openers, that could reduce the value or even neutralize any collectability whatsoever.
If the oil is still sound, you still shouldn't use it in a modern engine of which the manufacturer's recommendations call for an oil rated at a higher API index than what's in the can

 

All above makes sense.
After doing a little research it seems the oil does indeed break down in far less time than these cans have been around.
I've got nearly 50 cans so was hoping to use some of it but doing so would be false economy.
Full and perhaps collectible they shall remain.
Now, who has a service station rack for me?

 

Ask Old Fox. He said he had a station.
This is one of the openers we used to use at work:



This is the other type:

 

Oh, yes, the slice-dice-julienne spout, and the church key.

 

I have several variation of those spouts around here somewhere, it's a(sales) display rack I'm after.
