Hello - my first query here. I have an A6 2.0 TDI 40 c8 (2019) - had the car about 7 months  - the top up oil warning has just come on - it still has about 2000 miles until the next scheduled oil change.

i want to make sure I top up with 1L of  the correct grade of oil - can’t find any clear information in manual or engine bay. A Quick Look online suggests 5W-30, but I suspect I need a specific VW-Audi variant. Can anyone advise?

 

thanks

Suspect it’s 5W30 LL. You can cross check on Castrol’s site basically any oil that’s VW 504.00 / VW 507.00 compatible. The LL is long life, but change at the next scheduled interval.

Thanks for the quick response - i’ll

check that out. Much appreciated. 😀

Or just buy 5litres Quantum Longlife 3 which is VAG’s own brand. I never extend oil changes out to c18k or 18 months, but change it annually if you do an average mileage. 
Quantum is available from a number of reputable EBay sellers. 5 litres will allow you to have enough ‘top up’ oil for hopefully a couple of years.

Regards,

Gareth. 

Thx - that’s great!

No- 0W30. Its written on a panel beside the bonnet latch. They only recommend you add .5ltr of anything above that.
