Hi got the a7 tfsi 2020. I'm getting close to service oil interval.  Originally got 0w20 engine oil changed by audi dealer.  My question is, still use the 0w20 oil or I can change for different ones like 0w30 or 5w30. Is got 30.000 mil on the clock.  Thanks for any advice 

Welcome Slawomir, 

If Ow/20( and I haven’t checked) is the specified oil grade for your engine, why would you want to deviate from that? 
You say the 5 year old 30 K mile car is due for service, at what intervals has it been serviced in the past, and what is your current annual mileage? 
Regards,

Gareth. 

Oil is changed max  every 6000 miles since I got them. Previous owner changed oil every year his doing 4-5k a year.  I'm doing round 15.000 +/- depending on holiday directions.

Can we take it was a one owner car when you purchased it? 
If so, it has been correctly maintained by the previous owner.

I think you are very wise to change the oil and filter at 6K intervals - some may claim ‘over serviced’ but…

Back to oil grade. I would strongly advise you to stick with the recommended viscosity grade, and to confirm the brand you use meets the VAG specification within that grade.

In case it helps:- I always use VAG’s brand -Quantum ( albeit, my grade requirement is 5w/30) usually available from reputable EBay suppliers. I use Mann or Bosch filters, renewing the oil filter every oil change, and the air filter every year in your case. 
Regards,

Gareth.
