V's Tri-Tip Marinade

This recipe came from recipezarr.com. I was looking for a tri-tip marinade and found this one. Sorry I don't know who V is : )

1/2 cup fresh lemon juice
1/2 cup canola oil
1/4 cup white sugar
1/4 cup soy sauce
2 tablespoons black pepper
1 tablespoon garlic powder
1 tablespoon salt
1 tablespoon onion salt
3 tablespoons minced garlic
1 tablespoons minced dried onions
1 (2 lb) tri tip roast, trimmed

1. Mix all of the ingredients except for beef in large mixing bowl to make the marinade. Place trimmed tri tip in a plastic container and pour the marinade over. Let stand in the refrigerator for at least 6 hours. Heat grill to medium temperature.
2. Place tri tips on grill at a 45 degree angle to establish grill marks and cook about 35 minutes, or until cooked to desired doneness. remove the tri-tips from the grill and let rest about 2-5 minutes before slicing.
