I don't see any point in flushing at all if the engine has been well maintained with a good fully synthetic oil (which will tend to keep it clean anyway). In fact flushing, if anything, will very slightly degrade the expensive oil you're just about to put it![]()
If the engine has unknown history then that might be another matter :chin:
Totally agree with Argonought on this, back in the day before semi and fully synthetic oil I suppose I could see the point of flushing, but if the service records for the car show it's only ever had quality synthetic oil used then flushing could actually degrade the new oil.
