For the more knowledgeable than myself. I have a three year old 2.2 Antara 163 hp. Has done just abt. 16,000 miles from virtually day one the display has informed me my avgr. return is 33.3mpg.
I set off today and the reading was showing as 24 mpg it crept up and the best I recorded for the rest of the 90 mile round trip was 29.3 mpg. NO difference in any conditions, driveing etc. stumped. Any ideas.
