First oil change before 5000 miles?
#16
My father was a mechanic and had one simple rule for oil changes "More frequent is better". There are endless debates about whether you should or shouldn't change oil etc with many valid points. The upshot is that as long as you can afford it (ie the $$ are not the issue), where is the harm in more frequent oil & filter changes (just my $0.02)

I always stick to 3K miles (5000Km). Oil and Filter. The cost is minimal (in perspective) and I have never had problems with any vehicle (Lexus or otherwise). It's a pain sometimes but better than having it off the road while it gets fixed

Moly in break-in oil is a friction reducer, by dumping it sooner, you are causing engine to have additional wear than leaving in until OEM's recommendation of change.
After break-in, it is also less engine wear if you let oil age a little. There is an official SAE paper published by Ford Motors Co. and Conoco Phillips. You can Google and find the link for this paper on-line, pay for it, and read it if you don't believe this link.

Engine wear actually decreases as oil ages. This has also been substantiated in testing conducted by Ford Motor Co. and ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119. What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it.

No idea of the source. I am a Researcher by background and reports/statistics can be twisted to suit an agenda.

As I said above. Still not personally convinced even after reading the above but not interested in getting into an endless argument over it. SAE Technical Paper 2003-01-3119 deals with a specific study on "Antiwear Performance of Low Phosphorus Engine Oils on Tappet Inserts in Motored Sliding Valvetrain Test". It is not a definitive test covering all facets of engine wear and all oil types.

If you discount all the evidence above, please present your scientific data to support "more frequent is better" in term of cost, time and resource saving, and less pollution.

I understand the debate about frequency of normal oil changes. Can you guys confirm that the oil in a new engine or car is in fact different than the typical engine oil (i.e. is the oil in the new car an "engine break-in" specific oil formulation?)?

I found documentation on the internet about Honda using break in oil but I cannot find anything on Lexus or Toyota. When I ask the dealer, I get a diff. anwser everytime.

You can compare with any Virgin Oil Analysis and see the spike in Moly content

See this link to explain function of Moly, which is a good friction reducer to prevent metal to metal wear.
