Just had an oil change

[Uncle Bob]

I'll get mine done next week when they do the oil pressure relief valve repair. http://www.renntech.org/forums/index.php?showtopic=8166
I checked the build date, it's 5/05 on my car. Close enough to a year for me.

oil changed once a year. I only drive approx. 6500 a year.

What about the 987's? The manufacture says you only need to do oil change every 20K miles. Are they full of it?

In a word, yes. Now to qualify, if I am going to keep my new Porsche until warranty end and then sell it, then by all means, I am fine about 20K changes with top off.

However, if I am going to be financially liable for this car at some point, then, no way is 20K OK.

Even AMSOIL would tell you that you need to start changing oil filters around 10K to keep the synthetic oil OK.

Several credible tests on M1 suggest 12K is pushing it, w/o changes in oil filters along the way.

To me, a 7500 change is fine IF I am on the hook for the engine.

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

As usual, Jim is dead on. The guys at Porsche who dictated the every other oil change rec. clearly know NOTHING about oil.

Isn't Porsche leaving themselves open to huge liability if their recommended service schedule is "madness"?
