This might be better suited for the oil analysis forums, but given that it concerns change over time I figured I'd ask here: how does one explain the dropoff in Pennzoil Ultra Platinum's boron levels from VOAs (in the 200s) to the used oil analysis (<100)? Is this a good thing, a bad thing, or...
I had the boss for such a short period of time that I couldn't tell you. I'm still keeping an eye on it since it could very well be a fouled PCV valve, dirty injectors or (god forbid) a faulty torque converter. Given that it's under 9,000 miles it shouldn't be anything quite that drastic. Air...
