What do you think is the cause or causes?

You're thinking along the correct lines. All of these "problems" are not really problems. They are perfectly normal with a new engine. Piston rings need to "seat" (or break-in), machined surfaces need to "burnish" (or glaze), and other factors lead to excessive oil consumption. BUT, this is normal to new engines. After the normal break-in period, and well beyond that in most cases, this oil consumption issue will not continue.

Again, this is not a problem. Unless there are some other mitigating circumstances causing oil consumption. (Usually covered under warranty.)
