Not too sure on this one, have been told by 2 different dealers, 2 different things on this.

if you are detonating in a 1.8T then you must have some REALLY low octane or a big problem...
9 times out of 10 the knock sensors will pick up detonation and retard the timing on out cars before there is even a chance of it causing damage...but when the knock sensors retard the timing there is a big decrease in power

i didnt know that about our cars...thats good to know. so basically if im reading this correctly even if you put non-premium in your car it will be okay or no?

EDIT: so you will basically loose power but your engine will be safe?

I have a story about using premium gas.
I use to use premium gas from Mobile. For the first few months of my car, everything was going fine until my CEL came on.
I bring my GTi into the shop and they say that I"m using the wrong gas!!! I didn't know you have to use a specific brand of gas in your car as long as it was premium. They give me my car back and tell me I have to use chevron gas only!!!!!!
Isn't that something! http://****************.com/smile/emthdown.gif
