Has anyone measured if there is any economy or drivability benefit of running a Twinair on higher octane petrol such as Shell Optimax, BP Ultimate or Tesco Momentum?
I'm just wondering if it would make sense to try switching to something like this on a long term basis with this engine or whether its unable to see any real benefit.
