Have just done the change with Quantum 5w30. That's what I had bought so that had to be that. Used your link there and got three results -
Cars AUDI A8 3.7i, -Sport P 1996 - 2002
Cars AUDI A8 quattro 3.7i, -Sport (QG0/2) P 1999 - 2002
Cars AUDI A8 quattro 3.7i, -Sport (QG1) P 1999 - 2002
QG1 seems to refer to flexible service intervals and states Quantum 5w30
QG0/2 seems to refer to fixed serviced intervals and states Quantum Platinum 5w40
The first doesn't specify service type but does say, like the QG0/2 fixed service intervals, Quantum Platinum 5w40.
Just checked on eBay and the Platinum 5w40 is cheaper than the 'standard' 5w30 I've bought. Thought 'platinum' would have been more expensive. Any ideas there?
Oil = very confusing
