Well according to the government site:
E10 is cleared for use in all petrol driven Ford models sold in Europe since 1992 excluding:
- Ford Mondeo 1.8 SCI from 2003 to 2007.
But currently I only do a few thousand miles a year (done about 7k in past 2 years total) so don't fill up often but really don't want more expense. Fill up on monthly trip to Costco, sometimes that's just a top up though and if more than half still there just leave for another month.
