Good question. The goal is to put together a "profile" which helps all of us understand how this was triggered. And your question should be part of that profile.

I wonder how many will admit to not breaking in by the book.

The car was broken in, by the book, from 10/14-1/15 . Started tracking it in Feb. 15 only at Sebring.
Drive the car to and from the track 200 mile round trip and have done 43 days on track. Almost no other street use. Using Mobil 1 0W-40.

Bronson is right. If you are limiting it to just GT3 seems you are good but it wasn't entirely clear since you also have some RS responses and can be interpreted as seeking RS responses too.

Okay good point Waxer. I will tweak my OP. Thanks for pointing that out.

1. No Issues - Prior to engine F 03048
2. Overall mileage - 13,050 miles
3. Track mileage - Between 150-200 miles
4. Engine mods - None

September-October build with November 2014 delivery, model year 2015, engine F 0100x (that's early!).

Break in by the book. Uses almost no oil. Smokes occasionally on start. Tracked two days, driven hard on the road. No track book included with my manuals package.

Maybe it is... but the other way around: most failed engines were broken-in by the book.

I would be very interested in reading whatever evidence you have about your assertion. Please post for our benefit the source of your findings.

I'm not sure what engine I have, but it is a 2015 GT3 built in December of 2014.

Approaching 9,000 miles, approximately 4,000 track miles.

No issues. I switched to Motul Xcess/Xclean after 1500 miles, have done oil changes at approximately 5,000 and 8,000 miles.

Car has been rock solid.

You would more than likely have the early F engine. Great to hear it's been rock solid.

And who 'asserted' anything? Guess you went right by my first word: MAYBE. Somebody said maybe the failures were due to no recommended break-in. I simply said maybe it was the other way around. There's no evidence either way. Capish?
