I used to have a Subaru Justy that called for 75W-90, it was thick as mud when it got cold! When it was below zero you almost had to slip the clutch until the tranny got warmed up, not the motor mind you but the transmission! I went with Amsoil 75W-90and never looked back. It's about the consistancy of 10W-30 Dino-oil, gained about 3MPG! Now I use it in everything with a manual trans Cars, trucks & motorcycles, for almost 30 years now & nothing has failed yet and shifts are smooth as butter hot or cold!
