Mine was the 5 cylinder with 165 hp. There certainly might have been better oils available in Europe that time, particularly if they were using synthetics for those longer intervals. There certainly is a difference, too, between someone actually taking the car out for a drive and the situation that faced my old Audi under the previous owner. He was a lawyer and all he used it for was to putter around town. He barely put 10,000 km a year on the thing, so I suspect there were a lot of short trips. And, you also know our North American habit of putting 10w-30 or 5w-30 in everything back in those days.
Like I said, it wasn't sludged up, nor was it immaculately clean. The recommended intervals, which might have been a tad optimistic on conventional, were likely followed.

It was for conventional. The manual stated to use a quality conventional and that synthetics were not required. There was, however, no prohibition against them nor any recommendation not to use them. As long as they met the contemporary API specification, one was within their recommendations.
Yeah, in the US 5cyl Turbo was little bit weker due to the octane rating and lower compression ratio.
I really liked that engine, although it never had appealing of BMW in-line 6 engines. There was a lot of problems with setting up firing angle on those 5cyl.
In 7 years that I live in the US i found out that sollution for everything is 10W30 or 5W30. When you ask people in oil place they immediately offer you cheapest possible sollution. It is remarkable!
When ever I change oil I always release old oil, put screw back, change filter do some other stuff, and then release again rest of oil that came down the walls of engine. Between two releases of oil passes like 20min. I always release half a quart of oil that stays in the engine. So I never truly grasp concept of 10 minut oil change places.
In one occasion when I was travelling, I stopped to change oil since it was due. So since I was not in my city, I just bought oil in Auto Zone and filter, and went to one of 10 min places. I had to explain to guy how to put filter and how much of oil to put! Even that was a problem, calculatin 4.2 quarts out of 5 quarts I brought!
