It appears they are relying on borate esters for the AW/EP's, and the base esters for their FM's.
The correct answer to your question is a definite Yes, with a qualifier. The same happens with a Full Flow Filter, it removes the larger particles, and the bypass will remove those particles down to say 2 micron. A few smaller, but for the sake of discussion I use 2 micron. So theoretically we are seeing the PPM of particles 2 micron or smaller. These are the wear particles. So in general terms I would say the analysis of a bypass filtered oil is just as accurate for wear. Now if you were doing a particle count then the bypass filter would show only particles below 2 micron in that count. (If some larger particles settled out in the pan, then some would be larger in the count.) This is general, and I am not discussing type analysis ect.quote:

The CR of the TDI is 19.5:1, down from 23:1 in the older 1.6 diesels.quote:

A chipped TDI produces boost upwards of 28psi IIRC.
Well your info is fine and dandy but I do not think Mobil designed the Delvac 1 specifically for a VW, modified or not. Do you ?

Mobil designed Delvac-1 for big trucks, not VW's. If they did, it would meet VW 505 specs like Amsoil does.quote:

How do you know Amsoil actually meets the VW 505 specs?quote:

I haven't had my oil analyzed yet. So far I've got about 4000 miles on Amsoil 15w-40. I'll change the oil when it reaches 10k miles and have an analysis done.quote:

Chris, how does this compare to your results, your TDI is chipped?
