This has been discussed more thoroughly before, but in general weight is not a very significant factor, but your mileage will vary.
Obviously, frequent stop and go driving will be more impacted more greatly by weight, but at sustained cruising, it's an insignificant factor.
Rolling resistance is not affected too greatly with added weight.
For most cars, the biggest drag is aerodynamic.
