I only use super premium plus. Not sure what octane it is since I think the German's use a different rating system. If you run low grade gas your PCM will recalibrate the boost to a low setting as a safeguard against knocks and pings I guess to prevent damage to your engine. I would recommend only using hig octane gas. It will take awhile for your omputer to reprogram and re-learn that you are using high octane, but your HP will return. Just my suggestion. I know it's expensive, but it's the only option for our picky cars.

Super Plus, equivalent to US 93 octane.

exactly...

Super Plus it 93 our scale, 98 German scale..
Super is 90 our scale, ?? German scale
regular is 87, our scale, ?? German scale

Can't remember the other German scale ratings since I only use Super Plus...

right now it is 58.5 cents a liter, it was up to 63 cents a liter for a while..

Meh....could be worse. You COULD be paying THESE prices.
That is great. I personally wouldnt add "Octane Booster" it only makes a fraction of 1 octane of difference on a full tank. If you really want to boost octane go buy Toulene or Xylene wherever they sell it over here and get any octane you want all the way up to 114!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!111111!!!!!!!!!!1!!!!!!!

I believe under the German measuring system, the super plus is 98FR

What about that "Ultimate" from the aral suckers?
I believe it's the same as V-power 100 from Shell. 100 octane. But I don't know if that's on the German system or American system, or just straight 100 octane unleaded.
