I'd be curious in the final answer... but it sounds like the original fluid had coagilated (sp?) before the MTL was put in (maybe the MTL loosened up the original gunk).

I got my car with 17.7k miles. I put MTL in at 20k, changed it at 30k, and just changed it at 40k. I run it HARD anytime i'm on the road, and also do monthly (sometimes bi-monthly) autocrosses.

So, I'm concerned, but doubtful.
