Demon, is that "insolubles" figure what we should look at in terms of air filter effectiveness?

And, did you change the oil filter at some point?


That, plus silicon, a few trace elements I had at 0, and any contaminents which they said were at 0.


No I did not change the filter. It was my second time using the Bosch synthetic media filter (~$4 at Autozone) and I am very happy with the results. I had used only Pure One's before that. (K&N for the SVT)

Being as it is only a small to mid sized filter I was impressed. I would Not have let it go longer personally even though the oil itself showed it could be extended.

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
