Mercon V is a snythetic fluid. I actually changed the fluid myself just a few days ago just to get the experience of doing it. Real messy, next time I think I'll just have the shop do it, but that won't be for another 30k. I just got the cheapest fluid I could find, I think the key is more like changing it on a regular basis. There was a bunch of little metal particles around the magnet in the pan. I'm wondering how they're going to change your fluid, whether they hook it up to a machine and purge the whole system or drop the pan.
Dropping the pan only gets out half the fluid, but you can change the filter and clean out the bottom of the pan. That doesn't happen when they hook it up to the machine and do a purge.
