[Vwdiesel] 0w30 Mobil 1

On the side of the 0w30 Mobil 1 container it says, "Exceeds warranty
requirements for gasoline and diesel engines and performance requirements of
BMW, MB, VW and Porsche"

This is a clean running new TDI engine that maintains consistent high speed
daily driving. The extra 5 mpg is good enough reason for me to use it. The 0
weight gets lubrication to it very quickly at start up.

Is the viscosity all that important on the newer TDI's or isn't it better to
have superior lubrication?

For the record, all my previous 6 diesel VWs (except TDI's) and current '82
Vanagon diesel use Castrol 20W50 in summer and 10W40 in the winter. I have
exceeded 200,000 on all of them but the Vanagon with zero engine problems. I
change oil regularly at 3,000 with them.
