Welcome to the new look VWWatercooled
After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.
Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before.
We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

Octane Booster Use (New gti onwner)

All the Chips are designed around 98 fuel (the ones I've seen).
some have an option of 95 fuel.
Stock on 95 should be fine here and there, but the car was designed to run on 98.
I ran out of fuel 2 weeks ago (well, needle below empty). Put in 10 litres of 95 to get me where I was going and next time I put in a full tank of BP98. No issues. I personally like using a petrol treatment every few thousand kms as well, used the Redline one last time, seems good.

They do not like 95. In Brisbane it was very hard to get 98 for a month or two mid last year (refinery problems after a fire). I had to fill up on 95.
I used octane boosters - they seem to bridge the gap OK.
I keep some in the car in case I cannot get premium.
