Best oil for an audi

[Bill1234]

I own a 2004 audi a6. What brand would be the best to use. Amsoil,Mobile 1, quaker state, etc?

[NickBlaine]

Amsoil was always my go to oil for my cars.

[Bill1234]

Im guessing I would go with the euro line as it is a euro car

[jvs1991]

What are they saying over on the audi forums?

[Bill1234]

They are saying mobile 1 Ow-40 or 5w-40 by castrol or amsoil

There's a certification it has to meet...if forget, something like VW502. If it meets that (there are many that do) you're fine. It would be in the owners manual or maybe on the oil fill cap. As jvs said, best to check audi forums for people that have had used oil analysis done. That's the only real quantitative test.

I use Castrol 5W40 synthetic.

[Bill1234]

I have the owners manual right next to me -yes I am that guy

[Bill1234]

manual states sae 0W-30 was first put in, but I could use 5w-30 or 5w40 which is better?

[Becciasm]

go with what the manual says and what they are saying on Audi forums.

Owned several Audis over the years and stick with Castrol Synthetic

[T3 AutoDetails]

I own a b5 A4 2.8 AWDQM and use Castrol 5w30

[Mach1USMC]

I have a C5 A6 4.2 Quattro - Amsoil 5W40 or Castrol if the Amsoil isn't available. And either a Wix or Mobile1 filter, none of that Fram BS:mad:

[swanicyouth]

I'm sure VW / Audi sells oil, as I know BMW does. Why not just use that?

Mobile 1 has a oil special for Euro cars it is 0W-40
