A friend of mine recently sent in this sample. The only problem indicated is the silicon. My fried read somewhere that there is a problem with the gasket on the intake manifold that allows a small air leak especailly in the winter and we are suspecting that is the cause of the silicon. Also he swapped the oil filter half way through the oil change interval, wix filter used both times. Thoughts?
Comments from Blackstone:
Silicon was the only element reading out of line in the first sample from your Toyota 1.8L. As it
doesn't appear to be affecting wear, we doubt it is from a harmful source. All wear metals looks good,
reading at or close to universal averages. Those averages are based on 5,000 miles, so your 8,058-mile oil
run indicates your Matrix wears better than most. The TBN read 2.0, showing some active additive still
remained. A TBN of less than 1.0 is too low for extended use. We think you could easily take the next fill up
to 10,000 miles. Nice first report and nice engine!
