the engine in my 2000 model Opel Astra 1.6 seems to be eating the fuel a lot quicker now than before servicing.
I recently got the car serviced, the fuel filter was okay the guys said and they changed the oil filter, teh air filter, plugs, brake fluids and changed the oil, well - so it says on the receipt they gave.
But now, the last week, the car is only getting about 450 km out of a tank taht used to get 650-700 km (52 litre tank) - not a very big tank but it would get me far enough, I promise.
So, why has it dropped by 200-250km in performance? Any ideas?
