However, you up in the colder regions of the country have nothing but praise for it...
So here is my theory on dino vs. synth: Synth is okay in colder climates, where the thickness of cold oil can make up for the slipperiness of the synth stuff. But here in hot weather, the oil gets thinner and the same slipperiness does not allow proper gear synchronization....

And I did the switch on a tranny with 150,000 on it, which is WAY after you're supposed to do it.

If you use a synth gear oil in a 5MT, should you, or do you need to add a friction modifier? Same goes if you have the VLSD, since the lsd isn't mechanical, should you use a friciton modifier anyway, or are you better off without it? :-\

Redline is a notch better than Mobil, but both beat all the competitors hands down.
Redline 75W-90NS in the manual 'box, shifts very smoothly in hot and cold weather - M1 lags little in extreme cold. Both have the friction modifiers in them already. Redline make a 75W-90 for non-LSD diffs, which would be good to use in conjuction with an autobox.

I use valvoline synthetic in the front diff because subaru suggests something a bit thicker than 75w 90 in the front differential. I forget the weight, 85w 90 or something similar.
I use regular ATF fluid because it is cheap and I hate my transmission.
