Hi I want to change my gearbox oil in my A4 1.8T just out of routine maintenance really.Looking in my local motor factors they had Comma semi-synthetic GL4 or GL5 in the Haynes it says GL50 plus all the usual sae numbers ect.Can I use either of the two Comma oils or am I better getting the exact one from Audi? many thanks in advance...
