Wash and pat dry the wings, then place into a big bowl.
Drizzle oil onto wings, then with your hands, toss to coat.
Repeat with chile rub, making sure that wings are coated well.
If you prefer a spicier wing, then place wings in the refrigerator and allow to marinate in the spice mixture for two hours.If not, then proceed directly to the grill.
Place each wing directly onto the grill and monitor, turning as the skin colors.
Cook to an internal temperature of 165 degrees F -- approximately 15 minutes depending on the heat of the grill -- then remove from grates onto a clean platter.
If desired, squeeze the juice of half a lime over the wings before serving.
