2016 Audi Q5 3.0L - Liqui Moly 5w40

[Storm897]

This car was bought new and at around 3,000 miles, was upgraded to a GIAC Stage 2 Q5.

Below is my used oil analysis from about 5 months of use and 4,050 miles. the oil was about 1/4 quart low which I take to be negligible.

A few notes:

• The 12 ppm of Aluminum is actualy around 5 because a Virgin oil analysis of the Liqui Moly 5w40 2040 I used showed 7ppm
• Not sure why, but the Oils viscosity thinned outt a decent amount to the point it was no longer in the 5w40 category. Not sure why this happened.

It's not unusual for a 5w-40 oil to drop into 30-grade territory, especially in a hard working engine.

Have you tried Castrol 0w40 at all? Works great in my 2.0T.

The viscosity index improvers didn't hold up. There's no other explanation.

Viscosity really took a beating, but it didn't seem to hurt much. Not sure why the 1ppm of Tin though.

Maybe you could try some other oil next time? Not a fan of Liqui moly, they surf on their "German" reputation, and that's pretty much all.

Yes that one, but you can get it at Walmart.com for $20 best oil for the Money IMO (for Euro Gas Cars Anyway)

The 2016 Maintenance Guide shows that "VW 502 00" spec'd oil would need to be "synthetic oil SAE 5W-40, SAE 5W-30 or SAE 0W-40". Does this mean that my 5w-40 sheering down to a 30w would be a reason not to worry? Either way I will try Castrol during the next oil change.
