Flushing was for the days of non-detergent oil. I used to flush the motor in my MG by mixing kerosine with 20W oil and letting it idle for 10 minutes then drain. It would desolve the sludge and make the the motor smile. This was on a car with mechanical lifters also, and the proceedure was recomended in the workshop manual.

Generally, there is no need to flush the old oil with any flushing product. That is normally an oil flush is not necessary. But if someone added the wrong oil, added coolant to the oil tube, then that changes things.
If you feel a need to remove as much of the old oil as possible the "flush" would consist of doing a regular oil change: If the oil in the engine is sutiable to run the engine with, warm up the engine some, then drain the oil, change the filter, install a new drain plug washer and a new filter housing o-ring, then fill the engine with the proper oil, type and viscosity for your location. Do not overfill.
Then start the engine and let the engine idle for a while or even advancing to driving the car a while -- hundreds of miles perhaps -- and then doing a full oil change again.
Depends to some extent upon why you believe an oil flush is necessary.
In some cases a thicker oil can be better. Depends upon why you think your engine needs a thicker oil.
Generally the bigger the difference between an oil's W viscosity number and its other viscosity number the more viscosity index improvers have to be used.
These can break down and that marvelous 0W-40 or even 5W-50 oil can be not so good if the oil run too long.
Thus a 5w-40 or 10w-40 oil might be better as long as the oil was a quality brand of oil, synthetic and met all of the requirements for use in your Porsche.
(I recently switched to using Castrol Syntech 5w-50 in both my 02 Boxster and my 03 Turbo but since I change the oil at 5K miles I'm not so worried about the viscosity index improvers breaking down before I change the oil.)
Oil additives... Used to be that my belief was that if I was using an oil to which I felt I needed to add an additive I was using the wrong oil.
However, recently I've come around to using Swepco 502 oil improver.
See the info at the link below:
http://www.swepcousa.com/lubesite/lubepdf/j03776.pdf
(I had some analyzed: It contains 200ppm of molybdenum obviously in a form that allows the stuff to remain effective as an anti-friction additive.)
Porsche techs tell me that using this additive helps reduce engine noise upon engine start and is particularly recommended (by them anyhow) for use in engines of cars that don't get driven regularly.
While I use my cars regularly I decided to use this additive. Whether you use it or not is up to you. I would advise you to consult the car's owners manual and if Porsche forbids using it do not use it, of course.
And before anyone jumps up and claims it is Porsche just trying to improve its bottom line a bottle costs just under $10.
Sincerely,
Macster.

Hopefully not to add to the noise...
