Discussion
Is it just me? But i cant say i notice any difference what fuel i put in, ive used 95 ron from the co-op 97 ron from BP 99 ron Tesco and ive even put in 100 ron when in germany and i honestly cant say i can tell any difference, the car runs well on all 4 of the above, ...........perhaps its me.

Nope, not just you! I've been reading this thread with increasing alarm. I thought I was fairly sensitive to car performance and set up in general - I used to do a lot of set up work for race teams - but I'm buggered if I've been able to sense any difference between any of the 'Super' grades in ANY of my cars. Even bunging in 95 if I've been stuck only seems to have had a very, very marginal effect (smooth running mainly) and even then only on a couple of cars.Edited by Pugsey on Friday 29th August 13:30
Modern M machines are designed to 'cope' with 95 octane fuel but not designed to run on 95. If you drive a fully loaded ( 4 people and their luggage ) M car and use big throttle openings and/or travel uphill when using 95RON, you'd hope the ECU's knock sensors were working properly to sort the ignition timing, otherwise......detonation is likely ![nono](/inc/images/nono.gif)
We should defer to the people who developed the machine and use 97RON ( or more ) if that's what's specified.
