Im after some oil for my 1998 a4 1.9 tdi quattro.

I know i need "SAE 75 W 90” (synthetic oil) according to specification G 052 911 A".

On GSF i found this '98048A FUCHS TITAN SYN GEAR OIL 75W-90 4 L AS REQUIRED (GL4/GL5 SPEC)'

Is this the right or wrong spec oil, and if it is wrong could someone help me out on which one i need, and where i can get it from.

Cheers

Chris
