A common Bitog sentiment which may be true but not in the way it is commonly expressed. The only actual fact we have is that VW has cautioned that 508 00 approved oil is not backwards compatible with other approvals, so rather than being a warranty issue with engines that specify 508 00 it is far more likely that it is to prevent its use in engines that do not specify the approval.i suppose the green tint is for warranty!! although YEARS ago i used a very good oil that cut my consumption by United Lubricants, + it was green + sold privately. but back then i knew little about lubricants but thanks to BITOG + other internet sites i learned a LOT.
Looks good. Like the 7.53 vis after 6800 miles.New to my friend, 2019 Tiguan. Convinced him to get a used oil analysis to see if there was any fuel dilution. The 508 oil we put back in was green. Wild. Filled with Mobil 1 esp x2 and a fram ultra
It’s possible since we didn’t know when or what the oil fill was. We were told an oil change was done before he bought the car but no way to verifyI honestly don't think the old oil is genuine VW 508. The genuine 508's usually hold viscosity even better than that. Add pack is not in line with the 508's I've seen either.
Oil still did fine for the shorter run but VW intends the 508 oils to go 10k and all the used oil analysis I've seen indicate it will do just that. This oil would not have made it.
Here's a chart of 508's, I'm sure it's not all of them but it's most of them 508 is not a real common spec. You'll see they all run Ca in the 1700-1900 ppm range with no magnesium . The Ca level and mediocre viscosity retention tells me that the drained oil in the used oil analysis was not 508.

No engine damage will occur by using an oil with a higher HT/HS but engine damage can occur with an oil where the HT/HS is inadequate. VW is trying (and has stated) that they are attempting to prevent this from happening.
My friend is afraid to put in anything other than what the owners manual calls for, for warranty purposes.Exactly. It was more than overdue to be said.

That's fine I tend to roll the same way, you did good with your selections.My friend is afraid to put in anything other than what the owners manual calls for, for warranty purposes.
There is a VOA of Ravenol VSE in the chart I posted above. Been a couple of used oil analysis on it here too, it holds up extremely well.Hard to say which is better, probably impossible to tell. Both are excellent.
Mobil 1 ESP x2 0W-20 is GTL + PAO + Polyolester, while Ravenol VSE is likely
(more of) PAO + Polyolester. Not sure if there's a VSE VOA, though you're
right, anything VW 508 00 approved is fine if used in the correct application.
VW (or Audi, as the 2.0T is an Audi development) did some tweaks on these
engines to 'strengthen' them for the use of thinner oil - e.g. they altered the
oil pump's chain drive (+10%).
