Engine Oil

My car is a 2002 A4 3.0 qS. The oil recommended in the owner's manual is VW 503.00, though the manual also refers to VW 503.01. I'm now finding it difficult to obtain 503.00: Castrol seem to have
discontinued the oil that I've been using, and replaced it with another 0w-30 oil (Edge). This, however, is manufactured to VW 503.01 and not VW 503.00.
The car uses a fair bit of oil - about 0.5l/2 months - so I need to keep some handy and want to be able to buy it locally (it's a bit of a trek to the main dealer).
Will I be OK using 503.01? Or must I continue to hunt for 503.00?
Does anyone have any opinions of Millers Oil? I hadn't heard of them until today, but have discovered that they seem to make an oil to VW 503.00. Not sure if it'll make any difference, though - I don't know if there's anywhere round here that sells it.
Thanks.
Peter.

Recently VW and Audi changed the oil specifications. I have a 2003 A4 on variable servicing which used to run on Castrol SLX Longlife II which I think is the 503.00/503.01 spec.
The norm is now 504.00/507.00 for the variable servicing which is Castrol Edge 5w-30 (yes, it is no longer a 0w-30 oil).
If in doubt, ring your local Audi service centre but i'm almost certain it's Castrol Edge 5w-30 oir equivalent you want. Also, since I started using this oil, my oil consumption has reduced considerably - which isn't a bad thing!

AFAIK, there's no oil that meets both of those specs. Well, I've certainly not found one. SLX LongLife II is what I've been using, but for which I haven't found a local supplier. It's made to 503 00, 506 00 and 506 01, but *not* to 503 01.

They might be using that for newer cars, but it's not even listed in my manual, so I won't be putting any in mine.

I'm pretty certain - albeit on the basis of that confusing manual - that it's not. I'm not even convinced that an Audi service centre will get it right: it was Audi Stafford that sold me 504 00/507 00. That might be right for more recent cars, but I'm sure it's not for mine.

Sure, I'd like to reduce my consumption, too, but I'm not risking putting incorrect oil in.
(Audi Stafford is the better part of 200 miles from home, and I didn't discover the discrepancy until after I got home.)
Wasn't life simple when you could just chuck 20w-50 Castrol GTX or Duckhams Q into any engine and know that it'd be fine? And oil was a lot cheaper then, too. Just as well - my old Mini used to burn loads of it!

I have a 2004 A4 and my manual doesn't mention 504.00 or 507.00 but regardless of that, these are now the recommended oils for my car. I think you'll find that 504.00 is fine for your car but why not try Audi customer services or ring round a few different dealers.

Audi have changed the spec to the 504.00/507.00 recently - obviously this will not be reflected in your service book which you got with the car when the 'old' specs were in use. The 504.00/507.00 specs exceed the old specs in every way. If you take your car for a service on the 'longlife' regime, this is what you're going to get.

Peter,
This may be useful - see here: http://www.castrol.com/castrol/sectiongenericarticle.do?categoryId 07840&contentIdp14782
Which is the replacement for the SLX Longlife II oil? A. This is the EDGE 5W-30 - the Longlife oil was a 506.00 / 506.01 specification - you'll notice that the spec on the EDGE 5W-30 is VW 504.00 / 507.00 - this is the latest VW specification for the Longlife oils and is backwards compatible; meaning it can be used where the 506.00 / 506.01 / 503.00 specification is required.
The EDGE 5W-30 is suitable for all Audi vehicles, and all VW vehicles that do not specify the 505.01 (fixed servicing), for which EDGE 5W-40 should be recommended.
