My e30 325e is not economical

I have a 1987 e39 325e and I get 390km/tank of gas.
The fuel consumption indicator goes to the extreme when I accelerate and goes to zero (sometimes) when I let off the gas. put in a new O2 sensor. Would changing the cluster fix it. Does anyone know what controls this operation. Vacuum system?
