Clocked 2000km on my C2S.. Had it since April. Hasn't used up oil at all. My question is can i drive it hard? meaning redlining it frequently or will i hurt the engine's life? All this time i've been driving conservatively - only once in a while reaching the redline. Patience is running out!

Would be nice if I could be convinced routinely driving your Porsche engine hard is quite okay. Would make sense for the short term, but if you're gonna keep the car for a while (beyond warrenty) it would seem better to be more conservative with the RPMs.

If I wasn't confident that my Porsches could sustain long-term hard use, I would probably consider a different brand.
In my experience, Porsches endure and thrive on hard use more than any other brand - one of the reasons I'm so fond of them and why they have an unmatched record in endurance racing. Certainly, the GT3 (with its classic split case dry sump design) is more suited to this type of use than most other current models, but the rest should be rather robust as well...

So, given Porsche's current "mass appeal" and sales boom, I'm not convinced Porsche hasn't taken similar cost-cutting steps. Sorry

I guess if one does not take his car out when there are a few rain drops falling.. then reving the engine would be scary too ( no offence)

you posted that you regularly ran your car on the back roads at speeds of "mostly 120's and 130's".
is that your conservative way to make the car last beyond warranty?

The oil gauge was one of the requirments of porsche clients on the 996 if i am not mistaken that considered that this instrument was necessary for a sportscar.

I bought my latest Porsche (997S) assuming ALL mfrgs of durable goods are making compromises these days. It's unavoidable. Economies are shrinking and pressures to reduce costs are on.
I was just questioning the basic premise, paraphrased like so:
Porsche engines are special, you routinely run them to redline and they work even better and last just as long
There's no proof of this. Seems like a shaky assumpotion to make these days.
IOW, the harder you make an engine work, the earlier it's demise, makes alot more sense...

I'm sure that Porsche knows the sporting intentions of its customer-base, and engineers the power-train accordingly. Would be stupid to build a high-end sports car that would fall to pieces if one were actually to USE it like a sports car full-time.

It appears that 993 heads are good for about 100 miles and the the valves are shot! Why? Air cooling.

So, I guess a 90-degree V8 motor would suffer from this phenomenon also, but only 1/2 as big a problem...

I've heard the theory in the past that the lower bore surface of horizontal cylinder engines wear faster, but do we really KNOW that it is true?
I have my doubts that the 1 g additional acceleration imposed by gravity adds significantly to the wear of the bottom bore surface when compared to the much higher lateral accelerations the piston is subjected to during high engine speed operation.
