Lead in oil

[Michael McLaughlin]

Hi everyone. I have a question about lead in the oil of my 2002 Passat  
V6 (it's the closest thing I have to an Audi at the moment). I got the  
car about a year ago. Because of my long commute (I've put 25K miles  
on the car in a year) I've been running Mobil 1 and getting oil  
analysis done by Blackstone Labs in order to maximize oil-change  
intervals. In both reports I've gotten back, the lead levels are a bit  
higher than average -- Blackstone says the universal average is 2 ppm,  
while the Passat's levels have been 7 and 6 ppm. Blackstone's report  
said this could possibly be a sign of extra bearing wear, but might  
not be. Is this something that should concern me?

Thanks,
