For those who still think that running the engine hard during break-in falls into the category of cruel and unusual punishment, there is one more argument for using high power loading for short periods (to avoid excessive heat) during the break-in. The use of low power settings does not expand the piston rings enough, and a film of oil is left on the cylinder walls. The high temperatures in the combustion chamber will oxidize this oil film so that it creates glazing of the cylinder walls. When this happens, the ring break-in process stops, and excessive oil consumption frequently occurs. The bad news is that extensive glazing can only be corrected by removing the cylinders and rehoning the walls. This is expensive, and it is an expense that can be avoided by proper break in procedures

When I see such language in the manual of the people building the vehicle, I'll believe it.

And FYI, my user's manual does not recommend any break-in, and recommends oil changes every 15000 kms, almost three times less often than for you guys. Does that mean I'm damaging my car, or do you guys pay for unnecessary oil changes ?

I just don't get it. Patience is a virtue.

I think I had 1200 miles on mine in like 3 days. I just couldn't get out of the car and HAD to get it past that break in point to see how she pulled. Man, what a sweet surprise !!!

The manual says to wait 1,200 miles, I broke loose at 800. I still apologize to my car to this day, but... Consider that these motors are pre-ran at the factory. They just want to avoid as much warranty work as they possibly can. Of course, if you go full throttle at 200 miles, you're not being good to your Z.
