Super Unleaded - i cant see the point - who runs it?

My gauge hits empty after 280/300 miles, but when I fill up, I can barely get 30/35 litres in. Ford gauges for the fail. I get pretty good economy considering I have a heavy foot.

My clio gets better though, like 360 miles on 30 litres when i rag the car everywhere, got almost 500 out of it last week on the motorway :p
 
My makes Mk5 Zetec S Fiesta always sounds like it's running rich with little pops in the exhaust. Sounds nice as standard, as did the other two he had. Maybe they all do to some degree?
 
Have had my Mk5 GTi from new (could have got a 760 :eek:) & have covered 30ishK, 20k with super & the last 10k with normal.

The end result? Cannot perceive the slightest difference...
 
Most ECUs will have passive knock monitoring.

They will run the preset ignition advance unless they detect knock, if knock is detected they will back the ignition timing off.

Kinf of similar to what you said, however they aren't really looking to advance ignition. Unless we are talking about the BMW M5 V10 engine which uses spark ionization to detect the knock threshold and actually run at the maximum possible ignition advance :cool:

Or you could have a '94 Trionic5 Saab 9000 which does the same thing.
 
no difference at all on my Speed Triple, used both with the right hand pinned and not one ounce of difference, as far as i remember theres 1 BMW bikes thats designed to run on it but other than that its pointless.
 
The Renaultsport Clio's are meant to be run on 98 ron.

I use v power in mine, as mine is mapped to run 98 ron too. Ive only put 95 in mine once when I couldnt get super.
As Ive only ever used super, I cant really tell if there's a difference, but tbh I fill the car up once a month usually, so the extra $$ is bugger all :)
