IIRC the northstar engines have a higher compression ratio than the supercharged 3800 yet the supercharged 3800 does need premium. Are you saying that the 3800 also does not need premium fuel? If you are, we've ran 87 in our 00 SSEi and it'* a dog with it. Fill it back up with 93 octane and it drives like an entirely different vehicle. Octane does matter.

Yes you do....the fact that I can even squeal tires is wonderful.
I did a few burnouts in my driveway today though. Put some water on the ground, lit em up on a cold start. Went to 6200rpm while spinning. WOOT.

luckily there'* a 400lb difference between the 95-99 V8 Aurora and the 01+ V6 Aurora. It feels much lighter. In fact, our 00 Bonnevilles feel much heavier when you're driving them. The aurora feels nimble in comparison.
