Nonsense?

Welcome Maineman, my advise to you on your pride and joy...enjoy her for what she has in her. If you are not planning on tracking her and simply want to enjoy time on the road, go with what the factory recommends. These cars have a lot of fun built into every engine and model and following proper care and maintenance you should have a lifetime of enjoyment from the car.

Changing the oil chemistry of such an expensive engine with additives is not something wise for the amateur.

There are seal materials, viscosity, flashpoint and other things to consider and I'll bet using such products would void your engine warranty if you had one.

Just stick to the Porsche approved oils list and you will be fine. Adjust viscosity slightly for your local conditions.

As far as the magic chips go, if they are really good, you'd hear about it in these forums and nearly everyone would have one.

I think there may be some in the ~$1000 price range that could help you if you actually have done some serious performance mods and you need the ECU
to take advantage of additional air/fuel flow to increase the power.

The cheapo chip effects are typically nulled out by the existing ECU as it attempts to restore the effects back to its programmed parameters.
