[s-cars] AAN oil specifications

[Tom Green]

You should ensure that the 5W-30 and 10W-30 oils carry the "energy
conserving"  API starburst and classification.  Audi service  
recommendations for
motor oil without this designation in these grades is limited to 60F  
and below, and
the additional caution to "avoid high-speed long-distance driving if  
outside temp
rises above the indicated limits".  This would apply to the energy  
conserving oils
above 95-100F.

The 5W-40 synthetic oil that meets the Audi 502 and 505 specs for  
newer models
has an energy conserving designation and appears to balance energy  
conservation
as shown by increased mileage with possible increased engine wear.   
The bulk of
the data is from 1.8T engines, but more users are showing benefits  
for the AAN as
well.

I think you should match the oil with a long life filter as well,  
since the thin-film oils
will need to filter out smaller contaminant particles, and to be a  
true energy saver
you need to extend oil-change intervals.
