58 PPM aluminum in oil analysis

[yamacheetah]

I recently did an oil analysis for my 2017 WRX. Full bolt ons, IAG 600 short block, flex fuel running e45. I wanted to see how long my oil life could be extended but most concerning is the aluminum content of 58 PPM. I will be monitoring knock/oil pressure per recommendation, but I haven't noticed much driving. Idk how much knock I could get with e45 fuel and a protune from yimisport. I have emailed my tuner, but just seeing if anyone has any feedback in the meantime?

One data point is useless. You need to watch the trend over time.

Has your tuner replied yet?
Get your oil changed at the scheduled number of miles your manufacturer recommends and forget about what the dashboard indicator says you have left in oil life. That indicator is not based on actually testing the quality, cleanliness, viscosity of the oil. It is based on an algorithm which probably looks at time or mileage since last change. I don't think ther are any cars that need to be changed every 3000 miles. Most can easily go 5000-7000 miles depending on the oil used (I recommend 100% synthetic)

what are you thinking the aluminum is even coming from?

I mean keep it in context, 55ppm is 0.005%
If you let a single drop of anti sieze fall in that oil that would probably make .005%
