oil type for B cycle engine B9.5 2020 A4 40 ?? ow20? 5w30? manual says nothing really

[Vinhouw]

I have been trying to find out the exact oil needed for the B9.5 2020 A4 (b-cycle engine?? i dont know what it means)as it seems to be different than the B9.

I want to do my oil change by sucking it up through the dipstick and dont want to risk to start mixing two different oils since some may stay in the engine even if I drain it from the bottom.

Some pointers would help!

I found this from audi, but again, im not even sure if my car is a b-cycle engine or not which require this oil:

508 00 / 509 00
– Castrol EDGE® Professional® 0W20 Long Life IV

Can't answer, but there should be a decal in your engine compartment that lists the specification and viscosity. All my Audi's have had one.

MY17-MY18 A4
"40" - gen 3 b-cycle at 190 hp
"45" - gen 3 evo at 252 hp

MY19-MY20 A4
"40" - gen 3 b-cycle at 188 hp
"45" - gen 3 evo at 248 hp
(engines are unchanged, someone just forced AoA to learn math)

MY21- A4
"40" - gen 4 b-cycle at 201 hp
"45" - gen 4 evo at 261 hp
(engines have 12v mild hybrid added)

So which hp do you have? Then you know.
