[V8] Manual gear oil (transmission)

[too many quattros]

that makes sense.  but usually a newer designations works with older and
newer.  this requires some research i think.

i CAN state that i have run and am still running EITHER MTL or MT-90 (based
on where and how the car is used) on about 10 vehicles (work and personal)
for the last 10-12 years.  they have logged WELL over 1 million miles and i
have not had a failure of any kind as of yet.  my highest mileage rig (an
audi 20VT 200q) has about 270K miles and it is still shifting great.

i do change the fluid every 30K miles.
