Rotella T6 5W40 UOA on 2013 Audi A6 3.0l V6 TFSI Supercharged w/76,795 miles. 14,000 mile run. Daily-driven with 10%/90% city/highway driving in southeast US climate. The customer missed his recommended oil change interval by quite a bit, but since most of his driving is highway miles, it didn't turn out so bad.

 
Fuel dilution looks to be low, which is a good sign on the direct-injected motor (though that is the 2nd gen FSI). How big is the oil filter on that motor?
 
Dang that's a long OCI for a DI supercharged engine.

Seems like 10k is a safe spot, I wouldn't extend it over 10-12k.
 
How do the intake ports look? Using a high NOACK, high SAPS oil (relative to the recommended Euro oil) in a GDI engine could lead to increased deposits.

It was a mistake the customer made. We recommended that he stay under 8K prior to the oil change. Thankfully the vast majority of his mileage is highway miles. As dgunay stated, 10K seems to be a good interval with his usage.

No makeup oil. It was only ~3/4l low when he came in for the change.

Thank you for that! We haven't examined the ports at all. When he hits the 100K mark we'll be recommending servicing the supercharger oil, which would make it a good time to examine the ports.
 
Wow. If this person drops to 10-12k miles, that engine will turn out great results. Looks like a match made in heaven.
