with modern oils and manufacturing processes (including the factory engine run) break in changes are going to be recommended in the manual if they are needed, if its not there no need to do it. i ran the challenger to 5k with the factory fill, got the first change done for free, then at 10k i changed over and put full synthetic in it. First full run after that i went by the oil monitor light, and sent the oil in for analysis to verify the accuracy of the light, checked out with a fair bit of life left in the oil when the light came on. The light on the challenger was running about 10k between changes when i was driving it every day, and modern synthetic oils are WAY more than capable of doing their job for that long(hell mobile one is advertising their yearly change oil for 20k miles, their legal department wouldnt allow that to fly without the data confirming that its safe), anyone changing synthetic oil earlier is wasting their money, with one exception, do NOT exceed manufacturer max change interval unless you are willing to give up your warranty coverage, in that case and in that case only could changing it earlier make sense. note:this is talking about street driven cars, if you track the car then you will have to do oil analysis to determine how frequently to change it.
now remember you will need to buy the more expensive filter to get the 10-15k life out of full synthetic oil, or do a filter change mid life, the standard filters would start leaking on me at the seal about 5k into their life, brand independant, went to a purolator pure one 10k mile filter and have had 0 leaks since.
i happen to have alot of this information from someone who works in the lubricants industry designing the oils that go into you cars, but its your choice if you want to listen or waste your money.
