Product Information

A tad harsh, especially given that you got the answer to your original question after the first reply. You pays your money and takes your chance. If I buy new Tiguan, VW specifically is saying VW 504.00/507.00 is allowed. Per Magnusson-Moss Act I can change my own oil in garage or parking lot as long as I use oil that is specified for that engine (though you are in Europe and that does not apply to you. Those laws are written for EU by VW probably). VW says VW504.00/507.00 is allowed. So, please, what are other markers. Because I actually do use oil that besides BMW LL-04 meets also VW504.00/507.00. I have not seen anything extraordinary in the color of that oil compare to Castrol 0W40 or any other oil that does not meet VW504.00/507.00. Again, even in EU VW allows heavy oils to be used in their "new" engines. Take into consideration that consumer in this case is much more protected in the U.S. then in UK. Maybe in UK VW can get away by claiming that owners MUST use VW508.00/509.00 (they do not). But in the U.S. that will not work. Keep in mind, OP lives in the U.S. The 508 00/509 00 specification specifically requires that a dye is added to the oil to make misapplication less easy. It is not a UV dye and it is not limited to a specific manufacturer, it is VW's requirement for all oils that meet 508 00/509 00. And as I said, if it came to a warranty claim there are other markers in the oil that can be found. VW tweaked that engine for Honda CR-V, Toyota RAV4 crowd, not VW crowd. They increased warranty since they want customers. They are being aggressive going after Toyota, Honda buyers, neglecting traditional VW customers. Problem is, Toyota/Honda customers are not as forgiving as VW traditional customers who are willing to live with some VW strings attached to get good driving dynamics for that class.

VW 508 00 is a specification issued and approved by Volkswagen (VW) for petrol engine vehicles with low consumption. The certificate refers to the latest low viscosity engine oil of 0W20 to reduce friction and guarantee fuel efficiency. For the best performance, the manufacturers recommend changing the oil two years or after 19,000 miles, whichever comes first. Dealer cannot figure out difference based on dye. Dye is there to spot leaks, nothing to do with grade. Tolerances in that engine are exactly the same as in my Tiguan. Nothing changed from that stand point.

Hopefully there are more mainstream approved oils soon. It doesn’t look like any crazy spec, so hoping Amsoil or another steps up to the plate.

If the oil is for top-ups then I'd avoid oil that is close, or has passed its expiry date. If you're looking to do a DIY oil change and using all of it immediately I'd have no qualms using oil only a few months past the expiry date. You'll see from the other thread I linked to earlier that I too was unaware of the expiry dates on oil. Every day is a school day. Volkswagen introduced its own specifications in mid '90s. Since then this classification system is the starting point for selecting the technically suitable products for all vehicles manufactured by the VW group (Volkswagen, Audi, Seat, Skoda). But, VW504.00/507.00 is still OK. Meaning, we designed those engines some times ago around heavier oils, and if you really insist you can use HTHS 3.5 or higher (actually maybe you should).Putting the 508 00 oil in an older engine is probably more of a concern, but if you're in warranty and want to preserve it the 508 00 oil is what is required and they can tell the difference.
