best way to break in a motor is let it fully warm up first. Then punch it and then coast down through the RPMs creating a vacume. First 4-5 times only bring to 4k, then do 5 times up to 5k. Then do a few at 6k. Then change the oil. Then drive like normal but make sure you let the car fully warm up for the first 1k miles. Thats the best way to wear in the Rings for best fuel eco and cleaner oil.

Thanks how my brother breaks in the new cars at his dealership and has never had a defective motor come in from his dealer.
