I recently sold my '06 Jetta TDI DSG (127k mi) and bought an '06 Miata Touring 5-speed (19k mi). The Jetta's DSG started slipping, and it seemed to be in danger of needing a very expensive replacement transmission. I've wanted a Miata for years, and now I have one!
On the Ecomodder forum, I've seen lots of
really interesting experiments and experiences with manual transmission oil. However, I haven't seen as much discussion about thinner
differential oil. Has anyone done any experiments with this?
I wonder if something like GM Synchromesh or Volkswagen G52 could be used in my Miata's differential?
I don't drive the Miata hard at all...my favorite thing about the Miata is that it's incredibly fun to drive without driving fast or accelerating hard.
