Last time I rented a van from Enterprise I had to TALK them into letting me have the oil changed because the oil life warning had been on for a week (had to rent because of junk Ford 6.0 trouble again) IMHO, it's not much of a priority for them-they just figure to unload the vehicles on an unsuspecting buyer, just as the warranty runs out!!!! The "P.T. Barnum" special!!!
