[V6-12v] Service indicator warning

[Lt.Kubosh]

I don't know about some environmental regulations, but they may exist in the
western Europe. "Longlife" oil in gasoline cars is bad step and VW is
comming back to classic (longer but fixed) intervals.
Those 9300miles (1mile is 1,60934km) is most common interval. While the car
is used for short distances (in town) it is recommended to shorten it to
~7500miles
It is because oil in gasoline cars is degraded by acids. Pour point is lower
and protection abilities are degraded.
In new cars have several sensors which are monitoring oil quality. In case
the oil becomes "bad" change oil warning comes. It has been advertised that
31000miles is the new longlife interval (better to say "up to"). Longest
distance I have seen was something about 15500 miles. The 31000miles
interval can only be achieved with diesel engine.
All my friends with new cars have switched to classic interval.

Only the car what really needs special oil is VW 1.9 turbo diesel engine
with PD (pumpe dusse) technology. Oil with certification VW50501 should be
used because of really high pressures on the camshafts.

I think it has to do with the oil filter. As far as I understand it,
there are some environmental regulations in Europe making it quite
expensive to discard oil filters. Thus, you see many of the EU cars
with long life oil filters (the ones by Mahle for example).

I've seen long life oil advertised on TV. Don't know what the
difference between that and normal oil would be. Maybe the viscosity
changes less over time or something for the long life stuff...
