Can you mix oil weights?

The trick is to thin it with AvGas when you shut it down.

Won't the gas all evaporate out the breather tube if you pour it into
the filler neck of a hot engine?

How much gas are we talking about here, anyway?

My Cessna 185 has a factory option for an "Oil Dilution" system. There is a
table, seconds of OD push per temperature.

This was very common in the bush, and before reliable engine preheating.
Once the oil warms up, the gasoline evaporates.

Best,

So it should be added to a cold engine just before start, then?

Great discoveries are not announced with "Eureka!". What's usually said is
"Hummmmm... That's interesting...."

Nope. Gas is added to the warm engine oil, just before shutdown. That way
the oil is diluted and thin for the next cold start. Pretty common on
radial engined aircraft.
