So, what do you put in your car Sean?

Castrol SLX Professional Powerflow LongLife III. I buy 60 litre barrels and use it in both the RS4 and the GTI

So, what do you put in your car Sean?

Castrol SLX Professional Powerflow LongLife III.

Which is the trade name for Castrol Edge if anyone is confused between the two.

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

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'!

Not entirely true as my local franchised dealer uses Quantum in its workshops;

Well I'd find another stealer - because Quantum are categorically NOT approved by Volkswagen Germany for official franchised dealership workshop use.

This is increadibly simple to prove. Look on VW Groups official electronic parts catalogue - ETKA. First, look at the RS4 model specific section - Group 1 (Engine, clutch), illustration 100-98 (engine oils) - and it categorically lists ONLY "LongLife3" oils (to VW standard 504.00), and gives the part numbers for the official 'Volkswagen Original Teile' oils. So this confirms that 502.00 oils are categorically no longer permitted in the RS4.

Secondly, go back to the ETKA page which lists all the Audi models in the left pane, click on the 'display function list' icon - select from the drop-down list 'Special Catalogues' > 'Chemical Catalogue'. Then select 'service fluid-engine oil' - and for ALL Audis, NO Quantum part numbers are listed - and so are NOT approved for workshop use.

If anyone has an old undated version of ETKA, it also used to have a much more in-depth accessories catalogue, and this would list oils from the mainstream manufacturers such as Shell, Castrol, Esso, etc - but this catalogue seems to have disappeared from the latest updates.

And if you have either ELSA-web, or pay to use erWin, then this will repeat what ETKA states.

so says the big 50L drums they have round the back of the workshop and the techs in it.

Huh - BS. Quantum categorically is NOT available in 50 litre drums. In fact, no such 50 litre drum exists anywhere in the oil industry. Excluding bulk supplies via a tanker, Quantum oils are only avialable in 1 litre, 5 litre, 20 litre plastic cans and 205/208 litre silver/grey painted steel drums. Castrol, on the other hand, ARE supplied to main stealer workshops in 60 litre green painted steel drums.

That and they have swapped between Castrol and Mobil-1 dependent on who has a supply deal on.

Yes, I fully accept that. Under the EU 'free trade' regs, any motor vehicle repairer is free to choose their own oil supplier. However, it is generally accepted throughout the motor trade in the UK (and demanded by Volkswagen Germany) - that official franchised dealer workshops ONLY use oils from 'premium' quality oil suppliers - so this would mean Castrol, Esso, Shell, Mobil, Fuchs, Total, Elf, Motul - and similar. It would categorically be NOT acceptable to use either non-manufacturer (and that categorically means manufacturer - such as Volkswagen AG or Audi AG, and not importer such as Volkswagen Group UK Ltd), or 'budget' oil brands such as Comma, Millers, Morris, Tesco, Asda, Halfrauds, etc. This is one of the primary reasons why you pay a 'premium' price to get a service at a main dealer - they MUST only use genuine parts, and premium quality consumables. You arn't paying for the posh coffee, or the wages for the fancy totty on reception!

This does NOT apply to the 'Independent Motor Trade' - they can pick and choose the level of 'quality' of products they use - as an example, one of my local Audi independents only use Valvoline - and he never uses any LongLife brews!

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.

And technically, there is nothing wrong with that - it is all 'above board'. However, I would seriously question why the stealer keeps chopping and changing between oil companies - it certainly doesn't inspire confidence for 'backwards' traceability should any lubricant related problems occur. Stealers, like any decent business, should build up long term relationships with their suppliers - and not chop and change at will. My local VAG dealers have had Castrol contracts for probably 20 years, and as much as I despise some of their 'practices', I thoroughly commend them for their oil continuity.

Re the comment on 'who knows what oil they used' - well this is a classic example of why I strongly recommend peeps supply their own oil. Not only will you have the re-assurance that the correct spec oil is used, but invariably, you will pay considerably less than main stealer prices.

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

The latter point first - from 2008, ALL VAG official workshops must ONLY use LongLife3 oils, irrespective of individual service regime (OK, there are a couple of minor exceptions, namely the 2.5 R5 TDI and the 5.0 V10 TDI).

The first comment that all oils work equally well - is pure BS. Even if you only consider 504.00/507.00 approved oils - there are considerable performance differences between differing brands. Yes, all 504.00/507.00 oils MUST meet the MINIMUM requirements of the relevent test methods - however, some oils (primarilly those from Gp5 basestocks) will noticeably EXCEED those said standards. OK, if you have a VW Polo with a 105PS 1.9 TDI engine - then ANY 507.00 oil will be perfectly adequate. But at the other extreme, with a high ouput petrol engine in a high performance heavy car, then there will be differences in how the oils cope.

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?

Firstly, the Quantum oils (providing the correct spec, ie. minimum 503.01 was used) are not 'dire'. Quantum oils are perfectly adequate - but a main dealer should NOT be using Quantum - unless you personally gave them your prior permission.

Onto the B7 - just TAKE IT OFF LongLife servicing regime. By keeping it coded for LongLife, but then carrying out an interim oil change - you can actually mess up the readings from the oil quality sensor, and actually prolong service intervals even further!

[Teutonic_Tamer]

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

Sorry, but that is a typical attitude of the vast majority of North Americans - you just can NOT seem to accept that high quality longlife oils can substancially exceed 10k OCIs! The whole ethos of the North American continent is to ignore the advice for high quality fully synthetic oils - and instead use cheaper inferior oils, but change them considerably more frequent. It was this kind of attitude which caused the oil sludge problems in the 1.8 20vT engine - North America made this a problem on epidemic proportions, yet this same issue was barely an issue in Europe!

consider:
large volume, almost 10 l, better dilution
good filtration system
good cooling system

Which all point towards LONGER OCIs !!!!!

oil runs hot (burns moisture off) but not too hot, see good cooling system...

And . . . . your point is?

if it's the correct spec and approved, and changed at<6k, any brand will do fine...

Nope - BS. An oil made from a Gp3 basestock will NOT fare as well as an oil from a Gp4 or Gp5 basestock - even IF they are both correctly certified.

[Teutonic_Tamer]

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.

Quantum are perfectly fine for all VW/Audis, and even the RS. The issue with Quantum is (a) main dealers should NOT be using Quantum, and (b) Quantum are NOT identical to their related Castrol brews.

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

I don't have any major issues with Shell oils in general (afterall, they are generally MoD and NATO approved). The issue I DO have with Shell, is simply that they do not confirm which basestocks they use. I am aware that Shell use Gp3s in some of their brews, and Gp4 in others, but they have yet to confirm in detail exactly what they use. And they have completely refused to advise if they use Gp5 - which, by their refusal, would imply they don't!

So if you cane your RS, or it is tuned in any way - look for a Gp5 oil - such as Castrol, Fuchs or Motul.

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

Mobil are well known to spend massively more on 'advertsing and sponsorship' than they do on actual product development!

Fuchs SuperSyn 5W -40
excellent oil
factory fill

Don't think so - NO 5W-40 oils are VAG factory fill.

And the issue regarding Fuchs being 'factory fill' is very hotly contested. Indeed, look on VWs own website and it states Castrol is the OEM oil company.

[Teutonic_Tamer]

So, what do you put in your car Sean?

Castrol SLX Professional Powerflow LongLife III.

Which is the trade name for Castrol Edge if anyone is confused between the two.

Sort of. It is actually the 'professional motor trade', whereas the Castrol EDGE is the 'consumer' variant.

[ArthurPE]

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

man, you hit the nail on the head, lol

[ArthurPE]

Don't think so - NO 5W-40 oils are VAG factory fill.

it was for US bound cars

[ArthurPE]

the long life myth is perpetrated for 2 reasons:
enviornmental (valid)
cost, cheaper for service packages ($$$)
again, with the labeling of Americans...
the UK and Germany have the same long life stuff, and people still change their oil more frequently...becasue it makes sense...more sense in the US since our cost is much lower...

the oil is cheaper, but not 'inferior', not for this application and service duty
you're making stuff up ..... again

or it points to more effecive lubrication over a given interval, not necessarily longer...

my point would be lost on you...for others, it means less dilution/contamination due to water emulsion

again, you are mistaken...
for this service application absolutely no difference...none what so ever...

0/5, not good

Wrong again!!!! ALL engines, irrespective of their target market, are filled with 504.00/507.00 LongLife 3 oils - even the ones bound for the US!

You really come out with some highly misleading shyte!

wrong, mine came with 5W-40, it was analyzed...
the engine was EPA typed with 5W40, to use anything else would be a violation of law (in the US)

you are the one slinging shyte, in more ways than one

[Teutonic_Tamer]

the long life myth is perpetrated for 2 reasons:
enviornmental (valid)

Both extremely valid points.

Oil is NOT an infinate resource - one day, it WILL run out.

again, with the labeling of Americans...
the UK and Germany have the same long life stuff, and people still change their oil more frequently...becasue it makes sense...more sense in the US since our cost is much lower...

More bullsh!t - the vast majority of peeps in the UK and Europe in general follow extended oil change intervals. This is supported by all marques of the Volkswagen Group, all marques of General Motors Europe, all marques of BMW, and all marques of Daimler AG. It is generally only high performance cars, such as RS Audis, M BMWs and AMG Mercs which elect for time and distance intervals. Turbo diesels can happily go upto 30k miles or 50k kilometers on the same oil - and the oil does NOT degrade, and NO damage is caused to the engine!

The reason Americans change their oil more frequently is based on old skool attitudes, and the lack of willingness to spend more money on better quality true synthetic oils.

the oil is cheaper, but not 'inferior', not for this application and service duty
you're making stuff up ..... again

Yawn - stop burying your head in the sand. North American basestocks are recognised worldwide to be inferior to basestocks from other regions. Secondly, why has the European Union BANNED Group3 basestocks as being classed as 'synthetics' - yet US oil companies repeatedly flout this EU law - probably to protect 'their own' oil companies.

You can speak to ANY unbiasaded triboloigist - and they will ALL state Gp3 is nowhere near as good as Gp4 or Gp5 basestocks - and this is proven by factual engineering, not some opinionated internet myth!

or it points to more effecive lubrication over a given interval, not necessarily longer...

What, which? If you are referring to longlife oils vs non-longlife - then the longlife are PROVEN - by the same ASTM tests which API use - to provide 'effective' lubrication for a duration of OVER twice that of non-longlife. Again, these are FACTS - something you seem to have a problem with!

my point would be lost on you...for others, it means less dilution/contamination due to water emulsion

What an utter load of bollox!!!! What evidence is there to prove that longlife oils are somehow less able, or are more suseptable to contamination compared to non-longlife. That is the most pathetic argument yet. You really know cock-all about oils!

again, you are mistaken...
for this service application absolutely no difference...none what so ever...

0/5, not good

Oh really!!!!
