Change it again at 30hrs.
Although I agree with the concept of changing oil more often than the manufacture recommends I am not sure that it is a good idea with a new engine for the first ‘run in’period.
Engine technology has changed over the years and a modern engine is virtually ‘run in’ when you compare it to an engine of 20 years ago. However the manufactures still uses the initial run in period to lap in some components and to condition some of the wearing surfaces.
It is hideous looking at an oil sample from a new engine but it is all part of the manufactures grand plan, let’s face it, to avoid a warranty issues the manufacture wants the engine to be as reliable as possible and if changing the oil at 10 hours would help he would insist on it.
Bear in mind that warranties are generally getting longer and so are service intervals, no manufacture in his right mind would offer this if he didn’t have increased confidence in his product.
I know someone will come up with a specific exception to this but as a general rule I believe it to be true
