For the chicken rub: In a small bowl mix all the ingredients together and use for the grilled chicken. You can store extra rub mixture in an airtight container for up to 6 months.
For the chicken: Preheat your grill to medium-high heat.
Rub the chicken and its cavity down with the vegetable oil. Season the chicken with rub mixture, remembering to season the cavity. Pour out 1/4 of the beer and sit the chicken on top of the beer can. Place the chicken in the center of the hot grill and cover. Cook the chicken for 1 to 1 1/2 hours, or until an instant-read thermometer registers 165 degrees F. Once cooked, cover loosely with foil and let rest for 10 minutes before carving.
