She didn't have them, so they said they wouldn't honor the warranty. She took it to another car dealer and traded it. No oil analysis, and yes I know what it is. It is performed on airplanes all of the time, I just think it is a waste of money for a car.

Of course timing belts are a different story in a zero clearance engine. My Supra can toss a belt and no damage is done so I'm not changing it until it fails or gets very bad. You get my point though. You change your brake pads every how many miles or do you change them when they need changed? What about your rotors? Wiper blades? Tires? Light bulbs? Alternator? Battery? I could go on but you get my point. I don't understand people who ream me for doing the same thing with my engine oil. You don't change out every bulb in the car every 6mos so why should I change out my oil every 3k miles on a naturally aspirated passenger vehicle that sees light duty use? Makes little sense to me too.
