Did a fairly short run in the wife's Audi.

Almost exclusively highway miles- the M1 0w40 FS held up much better

than it it did in the Tiguan daily driver.

Solid TBN left. Looks good. Was the previous oil change with Castrol 0w-40 or a 30 grade Mobil 1?

Where did all that titanium come from? M1 0w40 has none.
kv100 became a 30 weight there. Maybe typical for M1 0w40.

Looks like the M1 is treating your car well. Silicon looks a little high, but the engine is still newish and it does not seem to have had a negative effect on your UOA.

Nice work, thanks for the post!

The previous oil was Castrol 0w40- hence the touch of titanium.
