I love Redline products. I've used it in every manual transmission I have owned from my Yaris up to my race cars. Always delivered outstanding results.
My wife and I are a rare stick couple. The best manual transmission fluid I've used is Motorcraft XT-M5-QS. I have it in my GTI. It's a PAO synthetic and made in Germany. Not cheap however.

+1, the hands down winners
Winners at what? Not Mazda, VW, BMW, GM, Ford, etc. I use a ot of Amsoil transmission lubes but they don't work the best in every application and Redline certainly doesn't. You cant shift a VW 5 spd into 2nd with Redline in it under 32f, its horrible fluid in these units.
The Cheap Pennzoil synchromesh works as good as anything you could ask for. It 100% does matter what application its needed for, there is no best for all. Pentosin MTF-2 is a great fluid I would put up against Redline or Amsoil any time for some vehicles.

Although not spec'd for it, I put this fluid in my Crossfire (MB SLK 320) tranny this morning. Only drove it for about 10 miles, but the 1-2 crunch was gone and downshifts seem smoother. A year ago, I tried Amsoil Synchromesh (see link) with initial improved shifts, but it degraded quickly, and the tranny reverted to it's prior bad behavior.
Interesting that this Ford syn fluid is made in Germany, distributed by Ford Dearborn MI and has label instructions in English and French. Vive la difference at least for now. We'll see how this fluid holds up, particularly when it gets cold.
