Was the 91 unleaded actually E10 though? A lot of service stations now
sell
E10 and put that price up on the main price board instead of the actual
standard ULP price, and some don't have normal unleaded at all (usually
independents, etc. that I've noticed so far).

I reckon it's because you're getting fuel that has ethanol in it, perhaps
unknowingly because your normal outlet has substituted it for regular
unleaded?
