After some 400 miles I returned the car for the first service where the oil was drained and the filter changed, as the engine was under warranty. The Service manager attended to the task. He drained the oil, and then removed the filter. He was quite busy so it was well over an hour before the new filter, half filled with oil was fitted.... The hoist supporting the car was then lowered and the engine filled. Given what I had heard and read about the importance of promptly fitting a new filter once the old one has been discarded and then starting the engine, I was somewhat concerned that the pump would not prime.
I mentioned this to him, and he said "that it would not be a problem, if a pump fails to pick up then there is usually something wrong and as such it requires attention". As it would happen he was right. Oil light off, pressure straight away and not the slightest hint of knocking.
Even so, I still like to change the filter quickly, just like I always have.

How can I check if an oil contains ZDDP? The only 20/50 oils I appear to be able to buy locally are Millers Classic 20/50 mineral oil and Halfords Classic 20/50. Do these oils contain sufficient ZDDP - does anyone know?
