UOA on factory fill at 1200 miles Ford V10

[Whimsey]

Considering it's a brand new engine with 1200 miles on it when this UOA was done tells more about the importance of changing factory fill oil at less than 1,000 miles rather than judgement of the oil. There are other UOA's of "broken in" engines using 5W-20 in engines spec'd for it that showed good wear #'s if the OCI was not stretched beyond manufactures recommendations.

The UOA is posted over at the Ford Trucks site. Thought some of the BobisTheOilGuy folks might find it interesting: http://www.ford-trucks.com/forums/showthread.php?s=&threadid=180206

Where are all of the factory says to leave it in for the recommended time people at?. The most wear is when the engine is new. Same with the differential 's' and transmission.

Here I am!

My '03 Accord's factory oil was left in for 3864 miles (3 months). The first oil change was with Pennzoil 5W-20. This oil was in the vehicle for 3670 miles (5 months this time). Here is the UOA for the Pennzoil:

Not bad for leaving the factory oil in for almost 4000 miles, eh?
