Basically the manufacture is going to go to the extreme to cover themselves - they aren't paying to have the fluids replaced but they are covering parts if they wear prematurely. So its really in the best intrest of the manufacture to have the fluids replaced before they are questionable.

That being said - is there any evidence that these fluids need to be changed ahead of schedule?
You know, engineers design things to fail. Sound crazy? If things worked 100% at all times, there would be no need for our services.

My friend's father works for a company that designs light bulbs. He was told that a light bulb his team designed had a lifespan that exceeded the limits. He had to make the light bulb more prone to failure. If they produced light bulb's that lasted forever, they would go out of business quickly.

That same mentality exists with all companies engineering teams.
