Why so long?

Range Rover Blues:
Cringe,  
NOooo.

Not on a V8, especially with the oil cooler.  You've more chance of moving the muck somewhere it can do real harm to the engine.  I've always used oil flush in the past but a mate who's been in the trade for years has recommended definitely NOT to use it in the Range Rover.
Besides, I'm changine the oil (any that hasn't been used) after about 3,000 miles anyway.  See if an oil change cures the problem.

If not keep using the magnatec as it will stop any excess damage during start-up.
Incidentally, is it worse in the winter than the summer?

RRC:
The problem has only occured in the past three weeks.

And it hasn't been particularly cold down here in Bournemouth. Oil change it is then.

nzrover:
When you change the oil use a good quality 20W/50.  I'd use the Pennzoil one but I understand that it's not readily available in the UK.   Don't use 10W/40 Magnatec or the like - it's a wee bit thin for the Rover V8 which can have trouble picking up oil pressure at the best of times.  The other thought is that the anti-drain valve in the oil filter has a bit of crap holding it fractionally open causing the filter to drain when it sits.  I'd suggest a quality new filter at the same time as the oil change.  And don't use engine flush for excactly the reasons others have stated.

Range Rover Blues:
Later V8s were recomended to use 10w-40 and at this time of year I wouldn't suggest a thicker oil, perhaps in the summer if the engine is worn then use a 20w50.  I use 20w-50 because our engine was rebuilt quite a while ago now and for racing so it needs a thick oil.  I top it up with 15w-50 which I think is a good compramise.

Xtremeteam:
i use halfords 20/50 £4 for 4.54 litres & a tin off wynns oil adative to make it a bit thicker,works great,used to see the oil light all the time & wouldnt go out till 2500 rpm,now not seen it in 6 months even after being reved to 65000 regularly
