2002 cab auto 330ci low mpg problem

Hi All

Ive owned in the past a 330ci coupe and 2 M3's ive since bougt a house now and gone back to the 330ci.

I have noticed i'm only getting roughly 20 max MPG. Ive just bought the car and noticed im using quite a bit more petrol than i did in the M3.

The car has done 70K and on aftermarket 19" wheels so i would expect to use a little more.

I'm wondering if I chnage the spark plugs, air filter, fuel filter and possibly ran some RED EX through it would it help me in any way ?

Many thanks, Ben
