Nope...if this is a dumb question i apologize in advance, but the people that switched to the full synthetic motorcraft stuff, did you guys add friction modifier?

After 15K on my MT-90, I have horrible diff whine at low speed turning under any weather condition. I'm going to try the Ford synth next.
The best fluid is Motorcraft Full Synthetic Manual Transmission Fluid. The part number is XT-M5-QS. Most Ford and L-M dealers have it in stock. Not cheap, but worth every penny.
It probably has been mentioned already, but what is the fluid change schedule for say "towing"?
fyi, I checked with Mazda about using this fluid in the transmission, as I was concerned about violating the warranty. They told me, after they spoke to Mazda, that the dealer cannot use this and they, Mazda, do not condone using it. However, the dealer also told me that if I were to fill it myself, they would have no reason to ask any questions about it........but......it still seems to me that if one were to use this stuff, and then the box went bad while it was still under warranty, then you might be up the creek without a paddle in getting Mazda to fix it. Ya just have to weigh the likelihood of something going wrong.
