Took my car for short road trip over the weekend for the first time and got a chance to stretch my S4's legs. Some nice B-roads and some highways.
The car performed flawless except I have 1 question on the oil temp.

I've bought my 2001 S4 early this year and since then, I've only driven it in the city. The oil temp has never exceeded 100 degrees C, but for the first time over the weekend, I managed to bring the car upto 200-220kmh
at sustain periods (ie 10-15mins) on the highway and I noticed the oil temp rise to and maintain at 120 degrees C. I realize T/C cars generally run at higher temps but is this normal? Ambient air temp was 25degrees C

Appreciate any comments

I would say this was quite normal - you can always fit the RS4 oil cooler, but it sounds like this was a one-off trip and not a regular occurance.

Agreed. 120 is typical when the car is run harder, especially with a 25 ambient.

I once had 140 on the track

140 is severe. I don't let mine get above 120.

Track use does do exciting things to oil and water temps, I have a little cruise round with the a/c on when these start getting high (the extra fan that comes on with a/c helps).

120 on a trackday, 100 spirited road driving. Other options for Oil cooler kits are available and quite a lot cheaper than the RS4 kit.
