Well, the MTX doesn't always need it. I changed mine at 50k and the oil was in good shape. A bit dark but not bad, no contamination worthy of note. I too went with the Redline and like it, but I could have easily gone to 100k on the MTX oil without a problem.

On the other hand it IS cheap and easy to do, so why wouldn't you on a reasonable interval? 50k miles ought to be fine for that interval though.

If you're having to swap it at 30k mile intervals IMHO you're being pretty rough on that gearbox and might want to rethink that.
