BMW X1 2015 N20 PZ EURO 5W40 5300 MILES

[KEVINK0000]

Sample 3 is Pennzoil Euro 5w-40.

1 and 2 was the QS 5w30 FS I took incoming fire on. BL is the QS VOA 5w30.

Was expecting much more fuel, I think this sample is skewed a bit, as it sat for many months after the change before being mailed in, I think the fuel evaporated once the sample was opened. Yes, I believe this is a thing.

Surprised about the metals since the oil "held up" better.

Maybe the change in chemistry had something to do with it. Do a second UOA at similar mileage with the same oil and see if it settles down.

It'll settle down on the second sample.
Viscosity held up so that's all that matters.
