Default 4.0 break in time

I would like to canvas the RL'ers here for some of their recommendations regarding the initial break in period on the 4.0 engine/tranny etc.
Is it the same as the .2GT3RS, ~ 2000 miles at under 4500 RPM, and no bouncing off the rev limiter ?
I would tend to believe that some of the 4.0 owners here, that live to the south of Canada, are well into and or past the mileage/break in period by now.

TIAFS

Driving my kid around for his hockey tournament in and around Sorel since Friday evening could have taken care of the break-in already.

Get off this forum and drive!!

For a few hundred miles: avoid redline, run thru all the gears, vary RPMs. I changed oil at 1200 miles, then started tracking it.

dont bounce off redline. vary rpm
if you dont exceed 4500 rpm for 2000 miles, rest assured, you will have the slowest RS in the world.

I followed Pete's procedure but just limited my rpms to say 7-7.5k rpms for the entire break in period. Plenty of second gear pulls etc and a track day at 1000km followed by a flush of engine and gearbox oils... Oil consumption is minimal and she runs a treat....

Thanks so much for pointing me in the right direction on the break in.
