Other mistake: The canister that Wrangler knocks over when he taints the Champ's fuel supply starts spilling oil onto the ground. A puddle can be seen being made from the spilt oil and is shown spreading across the ground just before the scene ends. When the oil puddle is found the next day, it is virtually the exact same size as it was the previous night when the scene ended, even though the puddle was in the middle of spreading across the ground.
