I thought it'd be the oil pump thing. When they entered my car in the system they also threw on a maintenance point that Porsche is apparently telling them to do--put some washers on the exhaust hangers. Apparently people have been reporting noise due to that.

Well, funny enough, after they did that, the sounds I was hearing went away! They didn't even have to try to troubleshoot the issue any futher. Good for me, good for them!

So yeah--take it in!

I have passed thsi info along...many thanks.

One of the more credible tests of M1 and Amsoil indicated that they were shot at between 10-12K miles, depending on oil comsumption.

That did it for me.

I was raised "Old School" on changing oil...every 3K miles. Hard habit to break even with the reaseach and development, testing and specs. provided by companies like Mobil & Amsoil. The Z with a 3.5 liter only holds 5 quarts with the OE pan...6 with the APS pan and I change that every 3.5K.

I 'll have to find a happy medium that I'm comfortable with for the Boxster. Right now 7,500 is sounding acceptable....given the volume of oil for the displacement of the engine. I just don't think I can trust it for 20K miles on a long term daily driver though...especially one I'm not driving. I 'll ask her to keep an eye on comsumption and engine temps ...maybe slice open the filter when we change them out to see whats going on in there.

No need to go to the effort of cutting a can open - the Boxster filter cartridge is a paper pleated element that fits inside a permanent housing. You'll easily see what is on the filter when you take it out.

The fluttering noise was diagnosed as "an oil pressure refief valve" that was manufactureed too short. They replaced the part with a longer one and the sound is gone.

No oil change performed on this trip.

Thanks for the helpful replies.

That's good news! Not a huge deal.

You should change that oil.......
