True dat - just checking, haha.
Though I think part of the problem is that the information provided by the manufacturer isn't clearly presented, or omits too much information, or isn't specific enough (or all of the above) - even if the end point turns out to be relatively simple to understand.
In regards to dealers, as the first point of contact, customers who have usually paid a not insignificant amount of money for their vehicles should be entitled to correct and proper advice and service, irrespective of marque - they always seem to advertise as such in their glossy brochures.
I quite dislike how, in some cases, the factory training, assistance and information the dealers (should) receive somehow manages to count for nothing in the end, but there we are.
It's a bit baffling, but what can you do, eh?
504/507 oils guarantee a certain level of performance, but that's not to say a 502/505 oil will always be a lesser product.
It should also be noted that a product which has not sought manufacturer approval is not always a reflection of its performance, so a product without 504/507 approval doesn't automatically render it inferior or unsuitable.
In addition, 502/505 standards can be met with a mid-SAPS formulation, just like 504/507 oils. There is no requirement for a 502/505 oil to be made with a full-SAPS formulation exclusively.
In any case, lubricant choice appears to be a secondary problem here. It doesn't explain why many other engines from VW that use 504/507 oils don't suffer from such high oil consumption as the Polo GTI does for instance. I'm strongly of the opinion that the primary problem lies with the engine itself (at least, that's the impression I'm getting).
Having said that, if a solution to the primary problem isn't forthcoming from VW for whatever reason, and if the goal is to eliminate, or at least, reduce oil consumption to a more manageable degree, then playing around with different brands and viscosity grades (within the scope of allowable VW oil standards, of course) may prove useful to those who have lost too much time and patience - though it's not as if you couldn't always do that anyway.
A band-aid fix it may be, but faced with the alternative of endless top-ups, it might be preferable than nothing at all.
