Ari, I have a few questions.  I just got off the phone
with the Mobil tech line, and he actually had
reservations about me using SHC50 in my tranny.  Me
said its viscosity equivilant is 90 weight.  He
thought I might have problems shifting when cold.  He
suggested that Castrol makes a product that fits Audis
specs. exactly.  SynthLube or something.  Can you
believe that?  Anyway, here are the questions.

1.  How cold are you talking about?  You are in
Greece?  I always thought it was warm there.

2.  Have you noticed any problems shifting when it's
cold?

Thanks for the input
