recently (about 10 months ago on analyzing my fuel economy i noticed that it seems to have increased dramatically by about 30 % measured over many fuel fills (at least 10) whereas on most forums they talk about 16 to 17 litres/100 km and my own experience being about 16.7 litres/100 km, it is now about 21 litres/100 km.
on a caravanning trip 2 1/2 yrs. ago i was getting about 19.8 litres/100 km now worse without towing one (recently when i towed that had shot up to 25 litres. /100 km.

any answers??

if you are going from 16/17 per 100 km to 21 per 100km then it's worse not better. scan for codes and check fuel pressure with a gauge. also check for a vacuum leak.
