Very interesting and some good data points. It should be put into the borescoring & IMS sticky as it also provides oil analysis (at 240kk) from both Blackstone and Speed Diagnostics.

Looks completely legitimate to me.

ATX_Native

Bruce has almost 200k on his 997.2.

Sporty

yes, but we already know that the 997.2 is the "golden child"

DesmoSD

Looks legit, it's from San Diego. In SoCal, you have one season (nice) and many roads to explore. PCASD has many driving events so seeing over 200K is not shocking.

looks legit to me as well and hopefully more of the norm rather than what gets discussed here. also, seems to support the argument that 911's from warmer climates are more desirable. frequent oil changes and drive it! funny to see the comments in BAT. I too drive my 911 from home garage to work garage. Wouldn't have it any other way.

misterdega

A well driven car. Good to see it.

Comments from the seller say the prior owner commuted 70 miles round trip 5 days a week. Assuming you work 48 weeks per year, that's about 14 years worth of commuting. Seems plausible, especially in SD where the weather is it's perfect 99% of the time.

have you seen the attached blackstone report in the ad? It's a first report so who knows how many actual miles on the oil before the analysis, but no indications of high alu content. Would the high copper content indicate rod bearing wear? Also, the high moly content seems to indicate this guy may have regularly used some kind of moly oil or additive.

Sporty

The oil has about about 4400 miles on it with no oil added in between? Plus, the Moly is actually low, not that high? Not sure of your point with reference to those items. The other wear items (which are actually higher in the SD report) are in the normal range per the Speed Diagnostics report/results which is supposed to be the superior analysis.

This is a very relevant data point we have here - two oil reports at that mileage, i.e., no outward/apparent indication of bore scoring and big bearing IMS reliability (which always come up on BAT) . Plus the fact that someone is offering 25k at this time for the car.... That being said, the car lived in an ideal climate and was driven frequently and for long distances each time .

Waiting on Groove to chime as this is "evidence/proof " of his hypothesis that he has been touting all along re higher mileage and the 3.6 vs 3.8 re bore scoring - but please Groove , no more pictures of you pristine 125k miles cylinder walls.

Not sure what to make of this. It could lend some credibility to the notion that if an engine is a ticking time bomb for either of the two reasons it will more than likely happen long before this kind of high mileage. And to what extent does the fact that this car's mileage was mostly accumulated with highway commute driving as opposed to stop and go city driving, a lot of cold starts and/or tracking contribute to the problem free 240K miles?

2009 C2S 188K miles

Ah, morning Illy coffee.... time to ruminate....

Back when I had my 2000 Boxster S and I frequented Porsche Pete's Boxster Board, there were a few of those M96 engines that went well over 200K... one guy got to... IIRC... almost 300K miles and he changed his oil only with Mobil 1 and according to Porsche's schedule. Look, these discussions about a good or bad engine is silly. We humans have a hard time getting our head around statistics... some go fast, some long. It is like our own health... we all know smokers who lived into their 90s... etc etc. etc.... Your particular engine, like mine, is a mystery until it isn't. I for one am not going to tear it down to inspect its internals just so I can feel better.

Beware rules of thumb... some are good such as change your oil early at 5K miles and add moly. Others are not so. I had the 2nd highest miles on the new M96 engine my dealer had seen and when I asked the shop foreman about the robustness of these engines... I had about 46K miles and they were failing all over the place and that is not hyperbole... he said something like "if yours went 45K miles, it will last forever". Well it blew the next week on a trip to Atlanta from Philly (the new crate engine lasted 150K miles). So.... I flat out reject most feel good rules of thumb. Even those that appear to be logical. Remember, for logic to work, it has to be based on truth... facts... axioms.... not assumptions or beliefs. Mr Navarro, Raby, Baz.. these guys have provided facts so we tend to listen to them... a good thing.

Anywho.... sure that car could have gone that long with the original engine.... and it could have missed oil changes... and on and on... it is what it is. Why is this a surprise? Mine at 188K is a golden car? Hardly... am I just lucky? Is it normal due to a better designed and tested engine? I dunno. I suspect that it is a better designed and tested engine but like we all spewed for years now, all that means is the statistics are shifted. So when we compare platforms, sure, my emotions say that the 9A1 is good and the M96/M97 is bad.... because I had two blow and this 9A1 hasn't... proof? No.

No matter what platform you own, or the age of your own body... just take care of it and you will (may?) shift the statistics. I see really only three items that "work": 5K oil changes, add moly, let it warm up before you go hard. I gotta stop, coffee cup is empty.

Peace
Bruce in Philly (now Atlanta)

plpete84

There is a 40AE 996.2 rolling around with close to 500k miles on the original motor. I even believe the owner is using Mobil1 0w40. Goes to show that if you drive and maintain these cars they do and will go the distance.
