I have a 2000 B5 Passat, with the 30v V-6, it currently has 33k miles on it. I have changed the oil myself since the dealer provided oil changes stopped after the 2yrs/24000 miles. Besides the dealer oil changes, I have used Mobil 1 0w/40 exclusively, and have changed the oil between 3k-5k intervals. I finally had an oil analysis done on the last change and got back that the oil, with 5087 miles on it, had a lead reading of 15, the universal average should be 3. The iron level though was 8 and 18 is the universal average. All the other readings were in spec and nothing was out of the norm. My question is this: They said in the used oil analysis notes that the bearings do not appear to be heavily worn (previously) but are wearing heavily (currently). I then e-mailed them back inquiring if this is due to lack of lubrication or to see what the cause of this could be. I was told it could be that the bearings are not being lubricated properly, but if that was the case other wear metals would read high also. They also said it could be from excessive idiling or racing, neither of which I do. I don't run this motor hard, but I do commute in the car daily. Btw, the motor is running perfectly, no roughness or unusual noise. I'm not sure what to do, as I'm concerned the motor is self dustructing. What could the cause of this reading be and what should my next step be? I have an etended warranty, will VW look at the motor just by an oil analysis report? Thanks for any help you can provide.
