oil is all good for spirited driving as long as it doesn't end with the number 30. i drove 4 k miles in the past 2 weeks... now topping 196 k. original owner was 10w40 then 15w50... I went a few dozen thousand miles of very abusive driving on 0w40 before finally changing to 0w50, with a splash of 15w50 in the summers. rarely changed it all these years out of pure disdain. still can't get the damn thing to burn oil or blow up. in the end, how many miles somebody got ain't a scientific poll. but, the endless numbers of junked cars [8 junked for every one still going?] balance out the propaganda.
under extreme rpms there's oil starvation to the number two rod and the guys need to stop revving the sons of bitches... anyway the thicker oils grease the bearings a tad for those crucial milliseconds during oil starvation which is sure to come but it saves them from exploding.

Like many of the others have said. It all depends on how well the car has been taken care of. My '84 has 245k miles on it and aside from a few minor oil leaks, mechanically it's been pretty damn good in my opinion. Electrically, now that's a completely different story.
Mind you, I have it on good authority that all three previous owners took very good care of the car (aside from one or two very questionable fixes, such as my shifter being welded to the linkage). I drive the car more often than my "daily driver" in the summers and, on occasion, really push the old girl.
All of that said, if they're properly maintained, and if you're not constantly beating the hell out of it, they'll go for a long time beyond 200k miles. Then again that argument could be had for just about any car. Except maybe a Pontiac Fiero.

I've used Rotella T6, Valvoline VR1 and Rotella TripleT in my 256,000 mile well-running 1988 n/a, and each worked well but with differing characteristics.
All three contain at least 1200ppm of ZDDP.
T6 for the dead of winter: quick starting and good (3.5-4.5) bar oil pressure in mid-teens F temps.
VR1 for the heat of summer: smoother/quiter flat tappet operation, good pressures.
Rotella TT for spring and fall: low-cost/good quality for temperate weather, good oil pressures.
I ran the synthetic for 7,500+ miles and paid for a Blackstone Oil Analysis.
Metals, TBN and TAN were still within good ranges.. could've gone another 1,500 miles.
To the OP, I had feared a 944 engine with 225,000 miles but 28 months of near perfection convinced my that these vintage engines are indeed robust.
A friend in Florida has over 550,000 miles on his original engine.

I have 210,000 miles on my '86 N/A with no issues. Runs really well. Switched to Royal Purple 20/50
synthetic at around 180,000 miles. I expected to see some leaks, but it's been fine. Wouldn't hesitate to track it again either.
