Sorry i know its not allot to go off so a bit more details:
Car is a 306 1996 mk1 (so it has the engine of the 405mk2). 1.8lt 3dr hatch-
the thing that struck me was it was great for the ammount of kms i was getting on the first full tank and then it went down - its still better but not as good. example - i got a bout 650kms per 50lt first run, then about 550.
so was wondering if anything could have caused it to lower in econnemy after being good....
again sorry for the lack of details,
