NY Taxi cabs routinely go 300,000 miles or more before either retiring them or rebuilding the engine. Why such great longevity? Because they never get cold and the oil is changed at regular intervals. 80% or more of engine wear takes place upon cold starts.
So, with our 993's, I try not to use it for short trips - unless the car is already warm. I've ridden with owners who "red line" their engines right out of their driveways. I always drive gently until the oil temp. gage moves off the bottom peg.
Other than this how do you drive? I don't "lug" the engine. Try to stay at 2000 rpm or more, generally near 3000 for most driving. But it seems to me if you habitually drive in the upper rev ranges, you have to be wearing the engine out faster than if you don't drive this way. It seems pretty basic. The more rpms, the more the mechanical parts have to wear.
What do you all think?

I am with you, I don't redline the car out of the driveway, and I will drive at the lowest rpm that gives me the power I need at the time. Engine wear definitely occurs faster at higher rpms. I have read about people who drive on the freeway in 4th gear, but why?
Cold starts are harder on engines, and I am also much more inclined to make short trips in whichever car is already warmed up.
That being said, I do like the run the heck out the car when the road conditions are safe to do so!

I drive around 3000 rpm. If I get below 2500, I'm downshifting. If I have to put any load on the engine (incline or whatever), I want to be closer to 3k than 2k.

Depending on where you live and traffic conditions there is no advantage to owning a Porsche or a Veyron over a Camry when in traffic, you are ALL going to go 50mph. Might as well let the car take a break. I don't jump it off of speed bumps or run over curbs either.

static warm up=bad
red line out of driveway=bad
short trips sometimes=not so bad
short trips all the time=very bad
driving the car under 4k to get the oil up to temperature and proceeding with long spirited drives=very good
and not forgetting the gearbox needs warming up too, sometimes takes longer than motor to get up to temp=good

Drive it like any other car?
Street cars, I can't imagine the guys who live closest to the Arctic Circle really ever get their cars warmed up. But do you guys hold back?
At the track, sometimes it's a cold morning and you're out first session (amazing how the fastest run group often goes first), no time to let it sit there and idle forever, so you just go. Basically by lap 3 you should know pretty much all you're going to know, absent suspension changes, it doesn't make any sense to hold back. Can't say I've pulled any of my engines apart and seen undue wear. Robust doesn't even come close to describing the drivetrains of these things.

So Ken, at what oil temp on your track car do you start pulling more than 4,000 rpm?
On a street car, of course, you usually have the luxury of being able to do a gradual warm up.

Whatever the oil temp is at pit out on the 1-2 upshift? Likely it's at least 100F, I mean even on the coldest days you'll have time to let it idle 10 mins or so as you're checking lug torque, fiddling with tire pressures, and getting yourself belted in.
My posts aren't attempts to be cavalier on the subject, just that when you're presenting yourself in the hot pits to go on track you'd better have your stuff in order and ready to do business.
