So the directions on the HobbiCo oil itself and the after run maintenance in the Traxxas owner's manual somewhat differ. The manual says to use WD-40 in the opened carb and the cylinder head (or if using after run oil follow their directions). Well the HobbiCo oil only says to use it in the carb venturi (opened carb if I'm not mistaken?) but doesn't mention the cylinder. Do any of you guys use it and if so use it in both or just the carb?
