Brandon King: Apparently liquid gold for Miata transmissions.
Works well! I think?!

ShopperShopper: After trying Redline, Royal Purple and other products I tried this on my 1990 Miata 5 speed and could not believe the results. Much less notchy especially in cold weather. Since then I have used this on my 1995 NA and 2006 NC with great success. At the 60K change interval on my 2014 Mazda3 I put this in my 6speed and could not believe the results. Should have made the switch sooner!

lrcox: I used this lubricant in my 2008 Mazda MX5 with 172,000 miles, after reading many positive reviews. In many MX5 FB groups this is known as unicorn tears due to the price. I was quite surprised by how much smoother my transmission worked using this product. I never had any complaints on how the car shifted, but there is a marked improvement with this lubricant.

Dylan Lewis: My first experience with the magic of this fluid was in my 1991 Miata 5MT. The car was super low miles when I bought it in 2012 (36K miles) and all the major mechanical parts were as good as new. Initially, I opted for redline MTL in the transmission and got a noticeable improvement in shifting when hot, but cold shifting into 1st and 2nd was still overly notchy and inconsistent. If you're really ripping it and doing rev match downshifting at high rpm, it would occasionally grind into 2nd.

After getting fed up with it, I did further research and found tons of folks singing the praises of this fluid. It's relatively pricey, but most Mazda manual transmissions rarely take more than two quarts so it's about 50-$60 upgrade, which is cheap in the car world. After buying some and changing out my redline fluid with 10K miles on it, the difference was IMMEDIATE!

Shifting into 1st and 2nd cold was absolutely buttery smooth. Rev-match downshifting at high-rpm is perfect with no grinding or excessive resistance. I eventually put 35K miles on this Ford fluid and it was good the whole way through. I changed it again in 2018 and I can say that shifting has always been a joy in...

David Coulter: I used this in my 6-speed manual transmission in my Mazda MX-5 NC. It did help smooth out the notchy 2nd gear shifting when cold, though it didn't completely alleviate it.

Christopher Lundy: This is the right stuff for my mazda 6 speed (mazdaspeed miata)
It shifts better cold than it did with the expensive aftermarket synthetic, and similar when hot.
