Sorry I'm a bit late with the official MG Rover version gentlemen.

You are quite right on that point
Kaiser. MGR says nothing about scalding. You know the old adage; each time a story is recounted, it is embellished in some way.
This is what MG Rover says:
"A significant amount of engine oil is retained in the upper levels of the engine. Should a level check be carried out on an engine that has recently been switched off, a low oil level reading may result. This may mislead dealers and customers into concluding that the engine has consumed a quantity of oil.
A revised oil level checking procedure has been developed and will be introduced into future editions of the owners handbook. The procedure is as follows:
- Ensure that the engine is at full working temperature. Turn off the engine.
- Remove the dipstick and allow the oil to drain down for 5 minutes.
- Clean the dipstick and insert it gently into the tube until the 'O' ring on the handle moulding is about to enter the tube.
- Slowly push dipstick fully home.
- Wait for 5 seconds, withdraw the dipstick and take the level reading.
Should a second reading be required it will be necessary to repeat operations 2 to 5 to allow the dipstick tube to drain down. Similarly, should it be necessary to add oil to the engine, operations 2 to 5 must be repeated.

It is correct, that it is smart to wait a bit after the engine has been switched off ... But more than a minute is a waste of time.

I think that the reason for quoting five minutes may be connected with the opening statement that a
"significant" amount of oil is retained in the upper levels of the KV6 engine. More oil needs more draining time.
