I can't argue with that, Saab has been unbelievable to my dad , the Porsche dealer in my hood is greedy and indifferent. My dad's car is in the shop they toss him the keys to a brand new drop top turbo with about 4k on the clock. It's smart business, he has repurchased there because of it, Porsche doesn't seem to care.

I am sure the 12,000 mile interval for 986 cars works great for the typical Boxster owner who never exceeds 4,000 RPM and spends most of the time cruising up and down the interstate.

For those of us that, use our cars it's a different story.

Oil threads usually never reach agreement.

I would say that I have never seen a used oil analysis that would support an interval near 20K on any Porsche.

Just my experience and who would want to risk this on a car that you are going to keep?

These engines are expensive.

I just find the possibility that Porsche would recommend an interval which results in the engine running on trashed oil fascinating. If the 20k oil is inadequate, by virtue of failing objective, widely accepted test levels, it blows my mind that the factory would recommend it. Awaiting a 20k test eagerly. There's bound to be many here following the factory recs, or?
