Mate, the oil goes thinner when warm/hot.  The advantages of doing this are numerous, including allowing the oil to drip off internal engine components and drain more freely.  Any possible crud in the oil is in suspension, which is what they're designed to do.  I do a sump plug drain because the flow of hot oil out encourages the purging of any residues in the sump.  Roottoot is right - oil showing the correct specs have to be just so, or they're contravening UK law in trade description.  They could also be liable if someone experiences engine failure because of misleading product info.  I like Mannol as it seems like a very professional company and I can buy 20l at a time.

Six years on!!!   I use Mannol 504/507 at 8-10k intervals.  It costs £50 for 20 litres and it brilliant oil - no issues at all over 60k miles.  I have never changed the sump plug or used a torque wrench on it.  In fact, when I got a slight weep, I just put a couple of winds of ptfe tape around the threads nearest the hex on the plug and it cured it.  Changed oil in cars this way for 40 years and never lost a sump plug or had any engine problems.  Filters have ranged from Crosland to Mann to Bosch and many more - never been an issue.

 

Oh, and I never use a pump - doesn't remove any crap/sludge from the sump.  I get it nice and warm and drop the whole lot out from the bottom!

 

So, I do my changes on my 2008 1.9 PD for about £17 and an hour of my time (leisurely pace).  Don't give the money to the stealers.

 

Whilst looking for some 507 oil to change mine and the wife's cars (using a SUCTION PUMP! )  I came across this link about Mannol oils as it seemed too cheap to me compared to all the others.

Interesting investigation of Mannol Oil claims.  It seems they are not all they cracked up to be:

Just food for thought.

I'm not too concerned as I've run my cars and motorcycles on Mannol oil for the past 8 years and have had no issues whatsoever.  I think the complaint is merely a paper exercise brought by bureacrats in the oil industry.  TBH, one could question the specifications of most oils and whether they're being entirely truthful in their claims.  I'll continue to use Mannol and drain from the sump - which is an industry standard method.
