If you do not break in your engine, it will not fail, it may be less efficient and may have more oil loss.

Here is a good article on why breaking in an engine is a good idea, it's all about temperature and heat tolerances. Even Chris Harris broke in his new GT3 for the first 1000 miles, did an oil change and off he went.

Not a need, per se, but breaking it in and doing a an early oil change may help with engine longevity which may help whomever winds up owning the car after the warranty period ends. I do it even if I don't plan to keep the car because I want to be considerate to the next owner and it costs me nothing to do.

Everyone is very focused on engine. You're breaking in everything... transmission, suspension, brakes... not just engine. What's the damn rush? Don't want to do 1,800 miles? Ok, do less. Procedure is more important than duration. Just don't pound on your car as soon as you drive it off the lot.

Also, don't listen to your dealer or SA. They are salesmen, not engineers.

Does Porsche recommend a 1000 mile oil change? I didn't think so. You'd think they would, if being overly conservative about the break in period.

There a lot of people out there that will buy this car and never put 1800 miles in an entire year. For that bunch of people I can see how running an engine in may be an issue. What do I know though, I have never followed that guideline and my cars are usually well over 100k mi by the time I trade in. Never an issue. YMMV.

Without getting too deep into it, I think most people (not you or anyone specifically) who don't consciously, actively break in their engines experience more oil consumption. Most people read break-in as "take it easy for 1000 miles" where in fact that's the worst thing you can do. If you don't want to rev it past a certain rpm that's fine, although if done methodically with time to cool down and not create hot spots it should be fine, but yeah. Break your engine in. Don't be passive. However you decide to do it, treat it as a procedure. All of my cars have had excellent compression and oil consumption. Far less oil used than the reported averages by other owners

OK, so exactly what happens at 50K or 100K miles? Do tell.

I agree, I use a progressive approach, first 1000 km up to 4.5K rpm, next 1000 up to 5.5, then next 1000 few runs up to redline, then after 3000 km let her rip when warm, no science, just what I do

I've posted this elsewhere but this was my experience:

Picking my car up at the Leipzig factory, I spoke to a Porsche engineer and a former Porsche driver and they both suggested not to go over 4k rpm too often during the break in period. They continued stating that getting your car up to temps gradually is more important.
Going over 4k rpm during break in from time to time is a-okay.
