Break-In Questions

[C-Pierce]

2.7 CIS, finally running and timed up great. runs like a top.

What are the general beliefs about break-in driving techniques?
Fresh complete rebuild
I know it has been covered many times but give a a guy a break..

thanks

Congratulations. I know you are relieved.

Here's a recent thread on the topic.

For a more in-depth, self-absorbed, but probably correct writeup, take a look at motorman's site.

I pretty much followed Wayne's and motorman's recommendations and can't complain.

Best of luck,
Mike

I second motorman's site. Drive the piss out of it with non-synthetic for at least 1000mi (or longer if you want). Verify that the rings are seated well with a leakdown and compression check. Then you're free to go to a synthetic. Use a good filter- either a Mahle, OE Porsche, or Mobil 1. Don't know what oil is good, read here http://www.lnengineering.com/oil.html

I really hate to bring this up..but after all I have read and I think fairly recently Porsche is recommending Mobil 1 0-40 (for all applications) and some people are using 10-50 I think it is in older 911's....on all oil attributes I know of synthetic comes out on top..so I use synthetic. I used the Wayne book break in method. I probably changed the oil a couple of times more than I should have before I changed to synthetic.

I'm like you, I've changed the oil/filter 3 times since the rebuild (about 1200 miles ago) and plan on switching from dino oil to synthetic on the next change. That was probably overkill but ...
