There is always going to be some wear metals in the oil, more before it's broken in. The only way to tell if this is normal wear is to compare to samples from the same type of engine. I run Amsoil synthetic in a Powerstroke and the numbers usually show slightly higher wear than normal (normal meaning oil at 5,000 miles). I run it 10,000 miles and the metals come back slightly higher than 5,000 mile conventional oil, meaning lower wear. I also use a bypass filter on it, Powerstroke injection systems need really clean oil to work right. If you can, find an analysis service that has built a database of what is normal for your engine, might try calling different ones to see if they already have an extensive database.
