Hi all,
Thanks for the input I do enjoy a mirage gear oil thread.
Just a few things:
1. I do the fluid changes myself and this is my only car so my use case is different from those of you with multiple cars / industrial mirage use. ie. to me it is worth it to spend a few more minute / dollars on fluid changes.
2. As I learn more about different options, I have been slowly changing to what is hopefully optimal, not trying to economize on money for fluids but applaud those who do.
3. My gear oil was changed at 6,000km (break in) and 16,000 km and it was clearly still good for both changes, I changed it to test a potentially better product, I intend to run the shockproof for what the manual says (49,000 km for mine).
4. Here are a few citations that I read which motivated my gear oil choices, again, I am trying to find the optimal, and add another data point with this particular combination of products.

5. Will obviously need to follow this post up with another engine oil/filter post because that is the most fun topic to argue about lol.
Thank you all for your expertise and insight, its great to chat with a group who loves the mirage.
