Had a quick search couldn't find much on the topic..
Last night filling up (again) I questioned which fuel I should be buying, so just filled up with normal Unleaded (97?) as usual..
I watched a video on YouTube this morning that compares 3 cars, a Megane, a Golf GTi and an Impreza, 3 different dyno runs with 3 different fuels with ECU reset each time.
The GTi and Impreza being performance vehicles had big increases on bhp when using Shell Optimax, as the engines were able to gain the increase from the 'better' fuel.
Would the GTi engines also benefit from 'better' fuel and also see performance gains?
Link to the video:
I don't really know how it works other than that the higher octane the less unexpected/planned reactions you get.
