[A4] Need for Premium Gas in 1.8T quattro?

[Doug Johnson]

I always used 87 octane gas in both of my 20-valve coupe quattros, figuring
that the knock sensors would retard timing to prevent damage from
pre-ignition.

Is the same the case the 1.8 turbo, or do I need to be buying premium gas? 

Please understand that I don't run around at WOT.

Thanks for you help.  :-)
