Yea, but I think people automatically assume that when you floor it like that, it's not gonna be economic, E70 X5 or not.

Unless you are in a Tesla roadster...then people might not know what happens when you floor it....

Yeah, I think so too but i considered it before ordering the X5. I think equipped in a similar way the Porsche is quite a bit more money, they option you to death more than BMW does. Free service is a big plus for sure.

I have the 4.8 and have been enjoying it since Dec 11.

The best I got was 13.? and that was after a 1 hour trip on the highway.

Now I am down to 12.6 all the time.

After the factory recommended break-in period, I would very higly reco changing the oil after break-in.After this, take the engine up to redline many times. This is as important as loading the engine correctly.

Hey Vin, I have lots of respect for you and have learned much through your posts, but this procedure you describe seems pretty extreme to me. I've had many new vehicles and have never broken the engines in this way. For my X5, I just followed what the manual says and didn't do the redline or the up-hill in high-gear thing. My MPG seems to be on par with everyone else's and she doesn't burn a drop of oil after 34k. I'd say the rings are probably seated just fine and I fail to believe it's a stroke of luck. If all this really made a difference, I'd say 99% of all BMW owners would be having serious problems with their cars as I'm guessing it's less than 1% of owners who actually do this.

Ask any engine builders how they break in fresh engine, street or race, and they'll tell you that it only takes only a few miles to break-in an engine, done properly. I said to wait 1,200 miles before redlining because I knew that few, if any owners would accept doing so otherwise. An engine may not burn a drop of oil and still not have optimal performance. This would show up in a compression and/or leakdown test. Then again, the engines may already be broken-in at the factory. It's not common these days though, since most engine plants now cold test engines without combustion. Here's a pretty good article about proper break-in.

best I can figure is he is reccomending this technique:

it is very controversial, but this is always recommended w/i the first 50 miles, not after 1200 miles as vin is suggesting...so not quite sure what his theory is based on.
