Phill,

The average reported gains by customers is 1-3 on gas vehicles but having driven a H-1 for a few months in the past and a few H-2 I also know there is a lot of wind resistance with the Hummer vehicles.
Depending on many other factors including the driver "style", tires,terrain,vehicle use, etc. (Mine was a bit heavy on the throttle) I would think 0-2 more likely on this type of vehicle.

Thanks,

GW
