I can't believe they let a car out that would need an oil change that bad. I've drove my vehicle 5-600 miles over recommended change and no trouble at all, let alone a oil light coming on. If it was due and Hertz rented it to these guys knowing they would bring it back in 10 hrs or so, I'd say thy took a chance. Besides, part of the rental agreement is for rental co to provide a properly maintained and safe vehicle.
