This may be a tad off topic but does Porsche still say their coolant is a lifetime antifreeze? If so, I don't buy it, just like I don't buy Mobil 1 should go 20k miles. Additives break down and contaminants build up.

Another example from another manufacturer is Volvo says their ATF is a lifetime fluid and the only maintenance required is visual inspection. Give me a break, everyone who knows Volvos knows the documented transmission failures and they know it is important to flush the ATF. With regular flushes (at least every 50k, ideally 30k) the Volvo transmissions last a long time (speaking of Mobil 3309/Volvo 3309 ATF here).

I guess my point is don't just blindly follow the manufacturer's suggestions, take it with a grain of salt (as most of the manufacturers own mechanics probably do), and look for other advice, if you study it you may find that there are better products and better advice out there (such as in the case of the Volvo ATF needing regular flushing).
