Currently I've got Redline MTL and MT-90 mixed in the Jetta 50/50 but I'm thinking to switch it to all MTL this fall. The MTL is a little thinner and should shift easier in the cold. The factory VW stuff is very thin and can be noisy in older cars. The mix wasn't bad last winter but would be stiff for the first couple shifts at below zero temps. I want to change again because the stuff that came out last fall was nasty and smelled bad. I've put 15,000 miles on the car and the trans is way quieter now...
