Can anybody give me some advice?
to another Mopar owner. We may be the last generation....
What engine in that Caravan? I'm assuming a 3.8 or 3.3. My first guess would be to check out the PCV system and make sure its not ingesting oil that way. 2 quarts per 4k OCI is a quart per 2k, which by the "rule of thumb" is not excessive... but a Mopar 3.3/3.8 v6
should do quite a bit better than that. If it were a 2.7 I'd attribute it to the quirks of that engine, but I don't think they put them in minivans.
I know you said there's no leakage, but look to see if there's just a thin film of oil on the underside. Slow leaks can blow away and coat the underside without causing many drips.
A slightly thicker oil *might* reduce consumption, but I wouldn't try that until I'd ruled everything else out, or even tried a different brand.
