Mobil 1 5w-30 VW 504/507 £8.50 for 1L ;-)

[RS04OUR]

I went to my local Audi dealer to buy some Mobil 1 5w-30 VW 504/507 oil, the cost being £19 for 1L at the moment to find they had non left.

I remember someone on here saying that Asda had an offer on this oil so I went there, and to my joy it's only £8.50 for 1L or £32 for 5Ltrs!

Thanks for the tip

That Mobil 1 is cheap for a reason - it is not as good as say Castrol Edge or Fuchs Titan GT1

Well, you live and learn - Audi tried to sell the VAG own Quantum stuff, which is best of those two IYHO please?

Quantum is quoted as being blended in the same place as Castrol for VAG using the same techniques. So theoretically the same.

The Quantum stuff is a special deal between Castrol and Volkswagen Group UK. Unfortunately, whilst the Quantum stuff is VW approved, it isn't 'Volkswagen Germany' approved for franchised workshop use. Official franchised workshops should ONLY use oil from a 'premium' brand (which would include Castrol, BP, Fuchs, Motul, Elf, Total, and also Mobil). Quantum oils are only meant for the 'Independent Motor Trade'!

Yes, Quantum is blended at the same 'UK Lubricants plc' plant in Belgium, which is where Castrol stuff is also blended. However, Quantum lubes are categorically NOT the same as Castrol lubes. Quantum are slightly inferior to the genuine equivalent Castrol brews (either the 'consumer' Castrol EDGE, or the 'professional workshop' Castrol SLX Professional Powerflow).

So, what do you put in your car Sean?

Not entirely true as my local franchised dealer uses Quantum in its workshops; so says the big 50L drums they have round the back of the workshop and the techs in it.

That and they have swapped between Castrol and Mobil-1 dependent on who has a supply deal on. My RS came with Castrol, AVS1 with Mobil 1, AVS2 on Castrol and since then I have changed out every 5k miles with Castrol but if I put it into the dealer who knows as both are in stock presently.

They say either works equally well and the even if you chnage to fixed service intervals still to use the same longlife 504 /507 spec. variant oil

Main dealer put Quantum in my b5 which i wasnt too pleased at after only finding out afterwards. Ive watched these oil threads with interest as ive just put mobil1 esp in the b7 on an inbetween service as i feel 15k is too much on the same oil but maybe im wrong with these latest longlife oils?

imo, any approved oil is as good as the other...
I don't subscribe to 10k changes though, 5 to 6k is what I do
consider:
large volume, almost 10 l, better dilution
good filtration system
good cooling system

oil runs hot (burns moisture off) but not too hot, see good cooling system...
if it's the correct spec and approved, and changed at<6k, any brand will do fine...

Uhoh, I see a throw away comment about to ignite heated debate!

Interesting info on the quantum oils, I've used quantum oils for the last 10 years in my VW/Audi's but none as hi-po as the RS.

When i went to the dealer to get my first litre of top up, they gave me Shell Helix VX

I'm looking for a brand of oil to find and stick with as I normally do, my choice was the Mobil too as been around for ages and easily available, feel myself getting confused again! LOL
