So it looks like after this 3rd report that all is well in my engine. All levels have come down except for a trace amount of fuel. My daily commute has increased significantly from the ~6miles/day, to 80/day now and there's a fair amount of track days on the engine now. It actually all looks to be very healthy for it.

At the bottom under "Properties" it lists antifreeze percentage. Dunno why my first two reports show '?'.

I looked at my analysis from 3 years ago. Looks like the only difference I see is that your Aluminum content is almost double mine and double the average. Wonder if this is cause for concern.

I'm not an expert, just reading.

Here was mine:

CU 3
FE 53
CR 3
AL 5
PB 1

Mine had almost 4% fuel. Which is high but not uncommon.

EDIT: it looks like others have had that high as well.

I'm not sure what the higher aluminum in the oil means. The block is iron but the pistons are aluminum, perhaps there's a slight amount of piston scrape? Could this be due track abuse? Is it a cause for concern? Would be nice to know.

I am not sure that it is a cause. I'd say if it were a lot higher it might be, but I wouldn't worry since others have seen it too.

I thought all Ecotecs were aluminum blocks?
