Does it "hurt" the car to go 5,000 miles between changes? Is it provable? Do driving condition matter? What breaks down faster, oil or rubber?
Do DIVING conditions matter? How can a "one size fits all" service policy be accurate? A divemaster in Cozumel, doing fairly deep dives in saltwater, on a daily basis has the same service interval as a weekend warrior in North Texas who only dives the quarry to 40 feet of fresh water--according to the warranty. Wouldn't time under water be a better indicator for service intervals? Why do annual service on a reg that sits in an air-conditioned closet for 350 days a year?[img]smileys/smiley15.gif[/img]
