But most of the time I've owned at least 2 and once 4 at the same time!
I bought my 2001 Boxster new more than 5 years and 55,000 miles ago....

If you go on Google and simply type in "piston speed engine longevity" you will find tons of different data to suggest that overall, increased engine piston speed kills longevity.
The engineers can verify this quite easily.
I am NOT telling you not to drive your car hard, simply suggesting you not justify it with a "its good for the car" story.
It is not.
Where is Minn Jim when you need him?????????????

No issue with the piston speeds, but most wear is caused by the first 30 seconds after start up, in comparison very little wear occurs after that.
Also I have read oil studies that show that new oil causes more wear in the first 3000 miles, after that wear levels out.

Hi,
" I try to get out, but they pull me back in..."
Nowhere is it written that it's good to intentionally abuse machinery. The harder you use it, the faster you'll use it up!
An engine and drivetrain is a symphony of moving parts. Step up the cadence, and you inevitably shorten it's lifespan. There are only so many cycles that these various parts are designed to achieve, push beyond this threshold, and the machine will breakdown short of the anticipated life cycle...
Happy Motoring!... Jim'99

My point all along is that it is better than leaving it sit, flooring it when cold, and shifting at low rpms. My way works or I am the luckiest Porsche owner of all time.
And I am not driving the car hard, just they way Porsche built the car to be driven. Try it you'll like it, Porsches are not to be worshiped, just driven.

I certainly never suggested that THESE practices were wise. Nor would I worship any car. I was simply taking issue with the "driving it hard is better than driving it moderately" school of thought.
As I said before, drive it like you stole it.if you so choose. Simply don't believe you can cheat the laws of physics. Stress kills engines!
Also, you CAN change your oil too frequently, but 7500 miles is NOT too frequent if one looks at the used engine analysis that are available. Depending on the oil, some are shot by then.
M1 is usually gone by 11-12K. Red Line will usually make it to 15K but then, why risk it with your $15K engine?

Probably a good idea. That way, when you've beaten one to death, you still have a couple more to fall back on.
Seriously, however, it is a testament to Porsche's engineering that they CAN be submitted to, shall we say, heavy service and still provide the reliability for which they are famous.
