That's good information. Thanks. You haven't got a part number have you? I've asked at 2 dealerships now and they're adamant it should be 5w30 longlife 507.00.

I think I'm gonna get it done to get the stamp, then drain it and put 505.01 in.

Hi,

I had a 2003 RS6 that the dealer put the 505.07 DON'T!!!!!!

It almost killed the car.

The PD TDI oil 505.01 is the only oil to use in the RS6 with the 4.2 V8

My car had the engine replaced!!

Good luck[]

I don't see how the oil would kill the engine, unless you're tracking it and hitting very high oil temps. Across the world RS6's are being filled with the "new" oil and they're not dropping like flies.

I have 5w30 in mine now because it gets bloody cold here (-20 to -30 no exception)

There's no magic involved, its just a temperature vs viscosity kind of thing and the differences aren't big. It's not like these engines rev to 8k+ where oil could start to foam.

I'm confused to why Audi went to the trouble of making an oil specifically for the PD diesel engines and recommend it for the V8 petrol ones? They are totally different engines in all respects.

In all respects other than the harsh operating conditions...

Did you really mean 505.07 which I have never heard of?

It's not only about the viscosity. There are plenty of 5w30 and 5w40 that you should NEVER put in your RS6. It's about the oil meeting the VAG specs.

The VAG spec for the RS6 is 505.01 as stated in the manual. These are 5w40 oils.

Because it says 5W 40 in the manual!

Synta Platinum 5w40 is what dealers should use.

It was only written 9 years ago...it's not unreasonable to assume there have been advances in oil manufacturing that make some newer oils a better choice. If Audi are now saying the 507.00 is fine, I'd go along with that. It's not like they'd be doing a recall of the manual. Unless I was tracking the car and seeing 120C or more oil temp.

I went to my local Audi dealer to buy oil, filter and sump plug washer to do an oil change myself.

They didnt have any Platinum 5w40 - "we only stock the 0w30 longlife oil"

I had to go to the VW dealer next door, which was part of the same group, to get the oil I needed.

The problem with what you are saying is that Audi have decided to consolidate their oil supplies, so that they can put the same oil in every car and reduce the stock at dealers, negociate better wholesale prices, etc.. Now *they* may have decided that 507.00 is as good as 505.01 (by the way, try getting that in writing that it is suitable for the RS6) because what do they care if you engine dies at 200000 miles instead of 300000. It's all good for them.

I hope you are right, I hope the 507.00 supercedes the 505.01, but I have never been able to have it proven to my satisfaction. I have the 507.00 in mine.

From a longetivity and oil film shear resistance point of view a recent 5W30 or even 0w30 can be superior to the old semi synthetic 5W40. Chemically there is nothing in an RS6 or other VAG engine that needs a particular kind of oil. As I said before I would base my choice on what kind of oil temperatures the engine sees. When Audi writes a spec they have to keep in mind a worst case scenario for oil temps, and back in the day they were making the spec there was not yet the luxury of low viscosity oils with a very high shear protection. (not economically feasible probably)
So they went looking to what they already had for oil spec that they could use and ended up with an old turbo diesel oil. So it's not like they "wrote" the spec to the 4.2 engine they just took the most suitable one they already used.

I cannot come up with any technical explanation why the engine would require this specific oil. The rotating assembly and bearings aren't rocket science and the loads aren't particularly high (power per cyl) so the only thing left is to worry about oil temp, I would not want to drive it hard above 115~120c with a 30 weight.

It's quite common for manufacturers and their dealerships to switch to a different oil than what's in the manual after X years have gone by. Normally influenced by what makes business sense, as the mechanical side isn't nearly as critical as they'd have you believe on other occasions. Volvo did the exact same thing switching to a newer 5w30 "longlife" oil in the older turbo models when the new ones started using it, even though before that they'd been adamant the only oil you could use was a 5w40 synth (even from a particular brand)

Not so. Put the wrong oil in a PD engine and you will very shortly be replacing the cams.

OK, let me rephrase that then, put any kind of modern A-brand fully synthetic in an RS6 and you'll be fine, probably those diesels too but I'm not really into diesel engines so know little about them.
