I only use my car at weekends but I still do 1000 miles a month on average - guess an Audi calls you to drive it more

Oh believe me, the call is strong. But current routine doesn't require much driving.

No worries, I did half wonder afterwards if that was the case

There's no scientific answer that makes a difference here.

This is one of those, what toothpaste, what razor, what underwear do you choose.

It is a personal thing, you do what you personally are happy with/want/need/like.

That's a simple question to answer - a tank full of oil weighs 47kg & reduces your mpg by say 1% but that decreases over time as the load lightens, a seat full of wife weighs 57kg & reduces your mpg by 1.2% but that load increases over time as she eats more pies... I'd worry about the latter more than the former...
