Reuse model a oil in another vehicle w oil filter

[Henry's Lady's Man]

Ok, this sounds a little wierd, but we don't like to leave unfiltered oil in the Model A for very long, thus we have recommendations to change it after 500 miles or maybe 1000 miles.
My assertion is that the oil is still good for an older vehicle which will filter out stuff relatively quickly, rendering a cleaned up and circulating oil that still has its viscosity and properties. I just drained a gallon of Shell Rotella 15w40 and am thinking it's still good; just needs filtering and keeping in mind the recommended oil type for the next vehicle.
Any takers?
