RE: oil usage
i assume that you mean 5k miles? i change oil at the 12 month rate due
to lack of miles on both cars. the result is that the oil in my audi's
is "thinner" i'm sure. a good hard run, followed by a top-up seems to
be enough to keep 'em happy.
both cars seem to use mobil 1 at about the same rate. 1 litre every
2-3,000 km's. after frequent early conversations about this sort of
thing with my earlier cars, i have absolutley no concerns about this
usage. i was told by an audi (germany) mechanic that the 20v heads will
promote more oil usage due to the oil feed design/ valve seals etc - the
owners manual talks about 1 litre every 1,000km being 'normal'.
