Castrol SLX source and spec?

[Diesel]

[Apologies for double posting]

The old girl [RS4] has done 6000 miles with me now and may need a drop of oil soon. Not having much luck searching for some online and I doubt petrol stations and Halfrauds will have Castrol SLX/ Other than stealers, any ideas where's best to get some guys?

Also (and confusingly) I believe that I have to use Castrol Formula SLX on my extended service intervals setup and NOT the seemingly better sounding SLX II longlife oil?

Thanks a lot if anyone can point me in the right direction!

You can use Mobil 1 503.01 which is £28 for 4 litres on offer in Halfords at the mo. Formula SLX is about 11-12 a litre at main stealers (who will sell you Mobil 1 too)

S3 and RS use the same spec oil you see

SLx II is the wrong oil for your car - you need 503.01

Thanks Dunc (& nice to meet you yesterday). Guess that's why I cant find any stockists - the stealers hog it!

Prob not the best idea to mix Mobil 1 & SLX so looks like I have an oil change jobbie this afternoon to do with 6000 miles left till service is due - if even Halfrauds can beat stealer prices, just imagine the price fixing that's going on Effectively a free oil change for her it is then...

you can get SLX in halfords now. in 4l and 1l containers.

just dont get SLX II that is also sold there.

Nice meeting you yesterday Diesel.
