Well, well! Thinking about changing to synthetic at 600 miles or so?
Although magazine articles on oil and running-in in procedures directly contradict each other from month to month, there is an interesting piece in this month's (next month's according to the cover – August issue) T.W.O. magazine. It's sort of saying that you can thrash your bike from new if you want to and then start running it in at some later date, when you are more inclined, or ready to draw your pension perhaps, because, "you can restart the running in process to repair and stabilise the surfaces later on."
Well, anyway, the bit about oil is this (and it comes from 'the highest authority', 'the world leading', The Castrol Technology Centre):
"don't splash out on a costly synthetic oil until your engine's covered [wait for it...] 5,000 miles."
Synthetic oils interfere with running in [because of a chemical process happening in the metals].
"Although you can treat an engine as fully run in after 500 miles, surface stabilisation continues for at least the first 5,000 miles of an engine's life. Synthetic oils actively prevent this from happening, possibly by holding friction surfaces apart. The consequence of using a synthetic too early is your engine will never run in properly. I would even suggest waiting until 10,000 miles before using it in most engines subjected to normal use. Until then you are best to use an inexpensive but branded mineral oil."
Now, what about a thread on 'the Beilby layer'? I'm sure that hasn't been done here before.
