Hi,

Interestingly, the Porsche Dealer Service Manual (Sec. 03 17) suggests an Oil ONLY Change at 20k mi. without a Filter change. It says:

" Note
· The oil filter only has to be replaced after every second oil change."

To me, this is absolute MADNESS! Probably Good for the Dealer though!

But, it does bring to mind a Caution for those having their Oil changed at the Dealer. Be sure to insist to the SA that the Oil Filter also be changed along with the Oil (wonder if this will affect the Price?). The Change has much more to do with removing the Dirt and Contaminates which the Oil picks up than it does with renewing any Lubrication Qualities. To keep a Used Filter, counteracts this purpose...

Happy Motoring!... Jim'99
