I've got a B6 S4 for which I want to change the oil and filter.
The car had had 2 services prior to my ownership using the longlife oil.
I then had it serviced by awesome who used 'normal' 10/40 semi synth. (which i suspect is the wrong oil?)
I want to change the oil+filter now but dont no what to use.
10/40, 0/30 etc etc
Which oil would you recomend? How much would I need? How much would it cost with a new filter aswell.
