SQ5 Oil Analysis

I reached out to AoA and they essentially said is not their problem, go away. If the dealer doesn't fix this appropriately I'll have to give my attorney a call. It was bad enough when they adamantly denied using the wrong oil when I kindly asked why it showed 5W40 instead of 0W20. I can't imagine what driving longer (the full 10,000 miles) would have done to my engine . I'm more concerned about the high metal content showing up so early .

For perspective I found this on the forum from a members Q5 3.0T and another 3.0T from an older SQ5 Metal content is much lower overall, the same goes for everything else. While this is an entirely different engine, I can't imagine how mine can be viewed as good

Here's the UOA's from my 370Z. First one on 6-11 was the Nissan Ester. At that time I switched to Castrol Edge with Ti (gold bottle) for two OCI. You can see the Ti pop up to 42ppm. Then I switched to Pennzoil Ultra the rest of the time. Ti drops back to negligible. As I understand it, the Ti functions in a similar way to Moly or Boron. It doesn't deplete with use. Castrol advertises this VW 508/509 5W20 to have Ti just like the rest of the gold bottle Edge line. BTW assuming you didn't hotrod your car, the fact that you live in Texas makes me not worry so much about the run of 40 wt. It probably didn't do anything. In fact I wish I could run a heavier oil. VAG made it clear when the partnered with Castrol for this new oil it was all about the fuel efficiency, not reliability. And I'm fully on board with how good oils are today, even the 20 wts., but with a change like this, you wonder if there may be some surprises for Audi engineers down the road. Like when GM raised the viscosity spec on some of their Duratec engines that had cam chain failures.

And as for the old 3.0T compared to the new 3.0T, they are completely different and the only thing that is carryover is a few bolts. The new EA839 is fully aluminum and has cast graphite iron cylinder liners, so you will get different metal readings.
Hope this helps.

Castrol yes, but OW30 is not exactly true. Please refer to this thread which breaks down Audi's recommends oils and viscosity types.

Hello - what I have stated about the factory fill oils and viscocities is correct.

Interesting finds here regarding the different oil type between the Q5 and SQ5.
I'm going to be vigilant on ensuring the dealership is on top of this when I take it in.
