I'm confused
 

I've searched about the break-in for the Z. Everyone seems to say 1200 miles.

The dealer told me to not go over 4500rpm until my first oil change which is at 3500 miles due to the possibility of metal shards in the oil from the new engine.

So which should I follow? I'm afraid that if I keep driving my car like a grandpa until 3500 miles, it's not going to seal well or perform well in the future

I'd follow manufacturer's recommended procedures.

I think your dealer is confused !!!!!

don't want to sound like an idiot, but are these in the manual?

I'd just drive it hard from the beginning.

the proper break in procedure is in the owners manual

yea, what the people on the site suggest is what the manual says.you can check it out if you want it shouldn't be hard to find.

Manual says under 4000 RPMs for 1st 1200 miles.

I didn't read anything after that.:)

:icon18:

Just drive it the way your normally going to. Unless its a track only vehicle it will be just fine.

It's actually 5000 RPM now for the 2007 model.
