Charles, I admit i am uneducated about this in spite of my sometimes harsh opinions... I apologize for some of my past harshness...
Questions...
1. They still sell leaded gas?
2. Wouldn't you need to do the analysis with the same gas, same miles, same ambient temps, same overall conditions, driving a similar way to really compare two oil analysis?
I would trust the two results more if EOS hadnt been added to the first sample.
It appears that you had a large increase in iron, sodium, boron, and lead on the first one too... from the 3 tests in 05/06 to 08. COuld any of this been because the oil was in the engine for 2 years? (06 to 08)? or perhaps the gas formulation changed?
In addition the lead wasnt that much higher in the two (20 to 27) and the lead was actually worse with the Redline. Could the 7 point higher on lead be to the 263 additional miles(20%+) and the EOS?
Seems like we really arent comparing apples to apples with these two comparisons.
I am no fan of BP, but I wouldnt be so fast to blame these variables on the oil alone...
