Wouldn't use anything but 98 ever. Unless caught in BF Nowhere.

Significant power loss even going to 95, yeah the ECU can detect the knock and adjust timing accordingly. But it's a 50k car, why cheap out on the fuel? I don't even do that in my 2006 Polo GTI.


Nearly 20kw at the wheels on our dyno. We can tell cheap fuel from the numbers, without even logging.
