It takes about 4 litres, as I remember.

Yikes!  That's the same as a Porsche, which, of course, needs all the 
cooling it can get from the oil!

>From what I've read in ams, they do.  The average age of the cars on
the road there is even greater than it is here. Especially with
Mercedes, where many people have more than 300 km. on their 190s, for
instance.  Many of these were documented in a recent article on the
190, entitled "Ironman".

If you think about it, the engine is usually the last thing to go in
most cars, and with the improvements in oil, I think it's about time to
get away from the 3K mile interval, making it at least 4 or 5K for
hi-mileage drivers.  Of course, as a lo-miles driver, I change mine
around 4 times a year.

BTW, I was mistaken earlier, the euro-oil-change interval on the S4 is
15,000 km, or almost 10K miles!  That's pretty long for a turbo!
