Good data! Thanks for posting!

This explicitly shows that oil analysis is the only way to know what the appropriate interval for your oil is. Not guessing, not the color of the oil, not what the advertisements say, not folklore. Science.

I love the recomendation for a 14,000 mile interval next time. And it will probably increase from there.

So, to put this in perspective Redpoint5, what is your driving cycle like? You're in Salem, OR so the climate is relatively temperate = good for oil life.

Oh, and for the curmudgeons, what did the Mobil 1 look like at 11,900 miles?
