Interesting information about the 5 classes, never knew that. What class would Swepco 306 be ?

And, how can one tell which class an oil belongs to from looking at the container ?

I've had cars where I have not changed the oil in 50,000 miles and have not had a problem. But i'm sure people would say I am nuts. :D

OK your nuts.
I do run the Castrol 10w40 in the Boxster. All my other cars run the oil called "On Sale".

Porsche has issued two TSBs on oils. One lists a whole bunch of oils by the country to be used in. The other specifies SAE 0W-40, 5W-40 and one or two 5W-50s.

Make sure API SL minimum, and ACEA A3/B3.

I used Motul 300V 5W-40 last year, a Group 5, maybe 4 oil that is very expensive. I'm going to Castrol Syntec 5W-40 this year to save some money.

OBTW LNE also makes a magnetic drain plug that I will be checking with upcoming annual change.
