Inevitably that loaner was filled up with the cheapest gas possible. Plus, it was a loaner - they get ridden hard and put away wet at best.
Though I do very much agree about the cheezy cost-cutting. I would have rather have paid $500 more for my car and had a lid on the console, the drink cooler, the underhood insulation pad, the nets on the backs of the seats, the rechargable flashlight, etc, etc. I actually have retrofitted a lot of that stuff to my car.
