I have this 2004 grand prix since 08. I have never been impressed with the millage on the highway. It has always been around 23-25 and that is running around 77-80mph. I really like the power it makes.
In the city it seems that with my wife driving it we maybee get 250 out of a tank ?
It has 90k on it, i run AMSOIL 0w30 SSO with a drop in K&N
any ideas would help ?
thanks,
Steve
