Preheat grill on high heat. Clean and reduce heat down to medium.
While grill is preheating make the rub. In a bowl, combine the chili powder, brown sugar, smoked paprika, and ground cinnamon. Mix well.
Rinse and dry off the pork tenderloin, place on a plate. Then pour the grape seed oil on top of the pork tenderloin. Sprinkle half the rub on top, rub seasoning all over the pork tenderloin then flip the pork tenderloin over and use the rest of the rub on the pork.
Once the pork is fully coated place on the grill. Cook for 20 minutes, flipping once at the 10 minute mark. Internal temperature of pork should reach 160 degrees Fahrenheit. Slice and serve immediately
