Tradition is to save it and use it as a wood oil so the wood will not decay after some time on the rain. Absorbs really good, doesn't stink or stick...

Mixed 50/50 with diesel is what I'm using as fence stain/sealer.

Was about to mention that. But you forget to mention the half-and-half mix of oil and diesel to prevent wood rot and insects.

If you got a very thick oil, yeah a mix of diesel and oil is good so it would lose on viscosity and would be easier to get it on and into the wood. But today's engine oils are not really that thick and can be used without any mixing with oil of lesser viscosity such as diesel. Nowadays you can find those very thick oils mostly in tanks (military vehicles) and big machines not your everyday family car.

I mentioned that in particular because the house I'm living has beams that were treated with that mix when it was built, back in the 40's. And the neither rots nor gets infested. But the added fire damage is there.

Isn't this what recently happened in Maui? A lot of tarred and oil treated houses... and a single standing one with a steel red roof?

Could be.

So you’re saying I have to take up an entirely new hobby I have no interest in just to dispose of my used engine oil?

Or just bring it to Walmart.

Can also be sprayed on your undercarriage to repel road salt & water during the winter and prevent rust, though it's not legal in every state.
