To answer your queries above in no particular order:-
The reference to Halfords is a generalisation as enlarged by bmc.
Most modern oils contain a modicum of dispersants but if you want to go the whole hog use a diesel detergent oil. Many years ago when employed as a mechanic in the local garage I used to look after several travelling salesmen's petrol engine cars and they were lubricated with detergent diesel engine oil and even after high mileages the engine/bearing wear was undetectable. The filters were always full of crap but that is where crap belongs.
To me there is only one generation of engine that counts and that is one of either generation that is in a serviceable condition.
If the engine is in good condition the oil pressure should come up straight away.
As regards my own Minor engine - after the first start any restarting of the engine is carried out in a normal Minor starting manner and the needle on the oil pressure gauge goes straight up to 70lb/in sq almost immediately on idle. So to answer your question the time to raise a useable oil pressure is only 2 - 3 secs at the most.
There is a difference in pressure between the oil pressure warning light being extinguished and a useable oil pressure.
As regards the coil getting hot it will take a long time for the coil to overheat to the point of failure so that is not a problem. As regards your reference to 9 volts for the coil - the minor should have a 12 volt coil and no ballast resister as usually fitted to 9 volt coils.
I hope that has covered it all.

Mend your engine before a rod ventilates the crankcase?

Fit an ignition kill switch between your distributor low voltage lead and say your sidelights.
It'll double as anti-theft device too.

Yeah, well.
What's the likely voltage at the coil when the motor is cranking please?

Do you know of a a 20/50 oil that contains a normal quantity of dispersant please?

No probs

Yes the system volts will drop when cranking, depending on how difficult the engine is to turn. Yes with my competition engines I Always cranked with plugs out before cold starts - had to change the plugs anyway. And yes - just don't pull the choke till you see the light go is the simplest way forward for a 'road' engine.

Who is your favourite engine oil producer please Sir?

For my competition engines it was Castrol - they gave me free cans for displaying stickers. These days Wilkinson/Morrisons is fine for my TR 7 and my warmed up 1098 Minor. Just don't expect it to last for ever!

Free cans, nice
You must have been winning.

Which oil did they give you please?

It is of course 'competition' engines... Using a BlackBerry while in hospital and it does crazy predictive things. XXL as far as I remember. .. It wasn't yesterday........

XXL
There's a blast from the past.

Serves you right for taking blackberries into hospital, whatever next.

People usually take grapes.
Is this a first for the MMOC forum, someone posting from hospital? Get out of there Mr BMC and back into the garage..

Get well soon BMC, hope your oil pressure is spot on too!
