Here is my second UOA when using Castrol edge black bottle.

UOA has no surprises. What will your OCI be once you are past engine break in?

With Mobil 1 you can actually extended the oil change intervals to 5k or 7k
First UOA was factory fill of course. This one is Edge black bottle 5w30. My next UOA will be with Edge 5w30 gold bottle 2.5 qts and 2 qts of edge 0w40. I was surprised the black bottle edge did not shear down to a 20 weight like some people said it would.

<span style="font-family: 'Verdana'">I'd be worried about that copper and aluminum. And I disagree with Blackstone; I think 9.06 is too thin for a 5W-30. </span>
Its a new motor and the copper is going down so im not worried. Aluminum is only 9 ppm why would I worry about that?

Even though you're still breaking it in, it's kind of odd that there was an uptick in aluminum so just keep an eye on it. And be careful following Blackstone's (or anyone's) advice on OCI's. They will not offer Powertrain Warranty coverage in the event of a failure.

Thanks. My first uoa was only 1300 miles so thats why the aluminum was less on the first uoa. I plan to use 0w40 from now on as well. The viscosity was still better then the factory fill at only 1300 miles as well.

I really enjoy doing these UOA's though and seeing the results. I plan to do one every oil change on this car.

You'd be better off with a 0w40 with the engine being that hard on a 30 grade, especially since its turbo-charged.

Sealants are silicone, not silicon. "Silicones, also known as polysiloxanes, are polymers that include any inert, synthetic compound made up of repeating units of siloxane, which is a chain of alternating silicon atoms and oxygen atoms, frequently combined with carbon and/or hydrogen. "
You'd be better off with a 0w40 with the engine being that hard on a 30 grade, especially since its turbo-charged. I wouldn't bother with half 5w30 half 0w40, go with mobil 0w40. It has a viscosity of 12.9 CST @ 100c, which is just above the max viscosity of a 30 grade (12.5 cst). Should shear down to a mid-30 grade with how hard that engine churns the oil.

Hope this clears some things up.
