Quick question, I've read lots of opinions on which oil to use in the s4, so I gave my local Audi a call as thought they would be best to advise. But the guy I spoke to said to carry on using what the previous owner used, as changing could cause issues, which I understand. But the previous owner used 0W40 fully synth, Mobil 1. Does this sound correct as I've not seen of anyone else running this oil.
The cars completely standard and on 94k.
Thanks in advanced
