I switched to Amsoil a couple years ago and I've experienced some light chatter when cold going around corners. Always goes away after everything gets heated up. Thinking about changing it to another brand sometime.

Stick a bottle (or half) of Fords best eau de parfum (friction modifier) in it

so i have a gt premium with 3:15 gears and did my fluid with amsoil in whatever the stock weight is called for but i didnt use friction modifier. In the book it starts you dont have to use it, so if your tracking the car and want a tighter lock up with the diff don't add any . if you want more street friendly use the modifier. now mine is a 19gt with a10 and its driven all year round , i never felt any difference not using ford friction modifier.
