How are you breaking in your GP engine?

How are you breaking in your GP engine?
Just curious if anyone is hitting it hard instead of go slowly.
Engines and lubricants have improved greatly over the years but generations-old advice has not. - See more at:
http://mototuneusa.com/break_in_secrets.htm
http://www.indiandrives.com/ways-to-...rsial-way.html Here are some of the many links out there that suggest you not go gentle because of reasons below and because this was the old school way of thinking because of technology at that time.
Fact? You decide. Engine Cylinder Walls Piston rings don’t rely on their spring tension to seal against the cylinder bores. Instead, combustion gases work their way between the rings and the piston and force the rings outward. During the first few minutes of engine operation, it’s important that the throttle be opened pretty far at lower rpms to provide this high pressure. Otherwise, the rings won’t burnish the cylinder walls properly, and the engine will have high volumes of blow-by—which means excessive oil consumption and shortened engine life.
I am just curious to who is doing what and not looking to start any arguments. Maybe by this thread you can monitor what each has done and then we can see what if any failure out there were do to how it was broke in.
We can also see who burns oil and who does not.

I'll be a guinea pig. While I'm not running the motor up past 5000 rpms, I do tend to give it full throttle for brief periods on occasion, usually in second or third gear. I'm also doing plenty of heel-toe rev-matching on downs (more out of habit since I'm a road racer).
I've done this in the past with BMW engines without incident.
GP mileage to date: 80.

3000 rpm Max., easy on the brakes, and don't let the engine labor. Will keep to this for the first 500 miles then go to 4000rpm for another 500 miles. Change the oil, then over the next 1000 miles bring it up to speed, after that let's motor !!

2000 Toyota Tacoma 3.4 v6 s/c with fuel management upgrade and water/meth injection. Broke it in with dino oil running it wot to 4500 rpms in 2nd and 3rd with a lot of engine braking (redline is 5.5k). Changed oil and filter at 400 miles to Mobil 1 5/30. Changed oil and filter again at 3000 mi.
2005 Toyota Sienna 3.3 v6 - babied it until 800 miles. Changed the filter and oil to Mobil 1 5/30. Changed again at 3000 mi.
I only did city driving for both vehicles during the "break in" period.
I put about 6000 miles on my truck in a year, so I do the oil change once a year. I only use oem Toyota oil filters either made in Japan or Malaysia. I do the oil and filter change 2x a year for the Sienna.
My Tacoma burns less than a fourth qt. of oil a year. The Sienna burns about 1.5 quarts of oil a year. Therefore, I'm adding about 1/4 qt. every 2 mo. My Tacoma has 72,000 mi. and the Sienna 80,000.

I'm keeping mine under 4k rpm, and making sure the engine is warmed up before driving, and letting it idle down and get fresh oil through the turbo before I shut it off. But I am putting some boost and load to it here and there, making sure to vary the RPMS.
I've heard the theories on the running it hard before and can't say their wrong, but can't say their right either.
I will change the oil about 1200 miles, then every 5k after.

Yeah, it falls off a bit around 90. The torque curve is pretty good IMO. You really don't need to spin it up much past 5000 RPMs to get it to really go.
I'm still loving the car but still do shake my head at the lack of keyless start and cruise control. If they left out the seat heaters, I'd be less perplexed.

Up to 950 miles, took it in yesterday and had the tires changed to the Continental run flats - not the ideal choice, but better than the Kuhmo's, runs a lot smoother. I also had them do the first oil change, now ready to explore the 4000 - 4500 rpm rev band for a few hundred miles. Loving every mile, seems so much more fun than my Clubman JCW.
