or better still actually use the car - under 300miles/month is doing more damage than whatever fuel you are using.
Maybe the engine won't get to it's best but at least the other ancillaries will be getting regular use. Swings and roundabouts and not too much to worry about as there is the small matter of a 3 year warranty

Anyway back on topic, my GTI has about 8k now Gizzy, I've used 95,97 and 98 octane and not noticed much difference in every day normal driving. Ragging it would be a different matter maybe but it runs just fine on 95.
