I like to get all that extra Silicon out a new motor that factory fill has, early. Silicon can be a wild card on new motors it seems to vary a fair amount. I don't think anyone here likes to see high Silicon numbers in UOAs. Do a search under UOAs "Factory fill" you will see what I mean.
As much as newer vehicles are any more I change factory fill out under 1000 miles. Why roll the dice as to how much Silicon you are circulating around all those nice new engine parts?
Many years ago when I worked in a engine remanufacturing shop for a couple years I got to see 1st hand a couple examples of what dirt ingestion (Silicon) does to cylinder walls over many miles. You would be surprised how many miles a motor will go with no air filter on it. Most here would not try it but those high Silicon numbers in a factory fill is along similar line. Silicon is nothing I want in my motors for very long.
Sure early OCI of factory fill might not have an effect one way or another. But I feel much better about getting rid of factory fills sooner rather than later.
