Hi,
This is the third report on the oil in my car - taken at nine ( 9) months. The testing was commenced six months ago to confirm the oil change recommendations from Porsche namely - 20000kms or 12 months for "normal" use
This then is the third report, nine months after the oil and filter were changed
The oil has survived for 11333kms (7038 miles) and nine months very well. Porsche's recommendations are looking very very good and with a big margin too!!
Ends.
I hope it is of some value even if the oil is now superceded in OZ and not available in the USA
