This year my son and I are moving up to Road Racing our 1.6 Miata in ITA. For the last 7 years I've run Red Line MT90 in the trans, this includes 5 years of Time Trials. Last year I noticed a problem shifting into 4th and a winter teardown showed severe wear on the the 3/4 fork. I replaced it and the 1/2(it had some wear). We just did the Double Driver School at Roebling and I noticed some sloppiness toward the end of Saturday(found a "no man's land beyond 5th) & Sunday(loose going into first). I drained the new fluid and it's blackish with a bit of burnt odor. I was told by a friend whose opinion I respect that you should NEVER use synthetic in a Miata trans.
I'm in a bit of quandry, do I stay with the MT90 or go to Regular 75/90?
Opinions?
Thanks for you help.
