Standard vs Premium Fuels

[MY95]

GTi6s are likely to notice a *bit* of difference...

They do have a knock sensor, so it SHOULD give you a bit more timing.. But I'd put money on them being calibrated for 95RON - unless it's gronky 95 then you're unlikely to notice a performance increase in honesty.

Some cars are just calibrated to run on 98 (mostly Jap, remember they can get like 103 at the pump!!) - most French stuff just isn't.

Thanks for the reply, I think I read somewhere they best run on 97+
What are they calibrated to run at does anyone know?
