Break-in period

It's interest to see all the opinions tossed around here, it would be nice if a real Porsche tech rep could be coaxed into explaining the break-in period and the oil change interval...

Hi,

Why? Just like the Salesmen, they drive Hondas. And, they're not gonna stand behind you if their advice is wrong. There are several opinions here which I'd value just as highly, if not more so, than many of the Porsche Techs I've met. Good Luck with the new ride...

The Honda manual actually specifies a break in period and methodology. Does the 987 manual?

The manual has a single page entitled "Break in hints for the first 2000 miles" (p. 19). It's too tedious to reproduce it all here. Quoting some of the key points as follows:

"This wearing-in occurs mainly in the first 2000 miles"
"Preferably take longer trips"
"Avoid full throttle starts and abrupt stops"
"Do not exceed maximum engine speed of 4200 rpm"
"Do not run a cold engine at high rpm either in Neutral or in gear"
"Do not let the engine labor, especially when driving uphill. Shift to the next lower gear in time"
"Never lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period"
etc....

Tre-Oh - How high did you rev it out during your "test drive"

Back in the days of aircooled 911s, the motors were run on a dyno for break in. I believe Porsche still said in the manual there is a break in period but, cmon, if its run on a dyno to red line at the factory, I think its fine.

That said, I have no idea how Porsche prepares/tests the new motors before they are installed. You can't do any harm by actually following the owners manual. So be patient. And enjoy

Hi,

I remember when Porsche did that. But, as you know, there's more to the break-in than just the motor. Synchros, CWP, Wheel Bearings, Ancillary Bearings, even the Rotors, Pads and Tires break-in and establish wear patterns. Observing the recommended Break-in procedure and schedule insures all of these bed-in properly for long service life...
