We are mostly US folk. Our ITR are designed for "premium" fuel as defined by the US compromise octane computation method, minimum 91 US "pump" octane.
The UKDM cars are also designed for high-octane pump fuels, but I can't remember the method for converting USDM pump/compromise computation octane to UK octane.
I think youi guys are still using the RON computation method.
