I haven't been on this forum in a bit. In addition to providing superior lubrication in very cold weather due to the 0W aspect of the oil, it is a true worldwide oil imported from Germany whereas the 5W-40 is a USA only formulation. Check out the bottles. 5W-40 is "Made in USA" whereas the 0W-40 is "Made in Germany" and then imported here. As a result, as of right now, the 0W-40 is technically a "GC" (German Castrol) as well. The Castrol 5W-40 available to the rest of the world is superior to our America only 5W-40 formulation. The American 5W-40 is made from Group III base stock whereas the 0W-40 is a group IV oil with a PAO base. NOACK is higher in the 5W-40. 5W-40 tends to leave worse deposits. 0W-40 oil meets more stringent specifications (MB 229.5) than the 5W-40 does because the 5W-40 is a cheapo American only formula that is not as robust.

And finally, for me, the kicker is that 5W-40, the worse oil, is more expensive! In my location, one can buy 5 quart jugs of Castrol (or Mobil 1) 0W-40 at Walmart for $25 or less when it goes on sale. At $5 per quart it is the best deal going for excellent oil that can compete in its performance with the more expensive boutique oils.

Edit: this obviously just applies to those in the USA. Those in the ROW get the ROW Castrol 5W-40 formulation which, to my understanding, is quite good except that its pour point is not quite as low as the 0W version for those that live in very cold climates.

Great info! I still don't understand if 5w-40 isn't good to run, or if the car runs better on 0w, then why does VW recommend it? I used the Castrol pro OE full synthetic. I order from ecs. From what I've heard, the dealers use some type of synthetic blend?

There's nothing wrong with 5w40 some just prefer 0w40 and some run rotella t6 diesel oil for more zinc. It's all preference.. I recently switched from 5w40 to 0w40.

I would prefer 0w40 but the 1st change was free and I'm a little on fence about doing changes myself as VW seems to be a pia in regards to warranty claims and self maintenance, just going by what I heard.

The dealers use the Castrol 5W-40 American blend that I discussed. It isn't a "bad" oil, but it certainly isn't a good one either. If you are getting a free oil change from the dealer than go for it. If you are buying oil yourself, my point was that you can get a much superior product (Castrol or Mobil 1 0W-40) for cheaper at Walmart. It is a no brainer. It won't affect your warranty as both carry the requisite approval (VW 502.00) for our 2.0 EA888 engine. As long as you use an oil that carries the proper VW specs you are fine.

I'm gonna look into this. The oil on ecs is almost $8/qt. I can't find it in my local stores.

The M1 is a little over $4 per quart when bought at WM in a 5 quart jug. Castrol is usually closer to $5 per quart at my local WM. Right now there is a rebate you can download from the M1 site that gets you $10 off a 5 quart jug that is good for up to two jugs. That down to less than $3 per quart. I usually stock up on Castrol/M1 when either one runs a rebate special since I go through a fair amount of Euro grade oil in my cars. Good luck.

I'm spending way too much for sure. I already purchased the oil for this coming oil change in a few hundred miles. I'm changing over on the next change. That's alot of money. Thanks for the info fellas !!
