Mine hasn't burned a drop of oil since I got it over 3000 miles ago. Is that normal.

If you do a lot of stop and go, condensation can build up and cause the level to stay artificially high...it appears yours did drop just a bit (they're normally filled to max) but nothing at all to worry about. Trouble begins when one primarily drives in stop and go yet the oil level drops considerably...hope this helps.

Thanks for the input. Actually, that level is where it was when new. I wasn't aware of the condensation possibility; that is kind of scary since it seems like it could cause corrosion. Wouldn't the condensation disappear if the engine stayed at temperature for a while? I rarely make really short drives.

Based on design changes on the EA839 engine, I would not expect "oil consumption" to be an issue, at all, especially given the track record of the EA837.

Take a look at the SSP as it indicates the piston ring changes to "resolve" this long known Audi problem.

Thanks. What is "SSP"?

Self study program.

It's technical documentation meant for Audi technicians. You can google them.

Otherwise I have posted a copy in the D5 A8 forum

There are additives in the oil that inhibit corrosion.

And it would be burnt off without issue. It's fuel dilution that is a concern. Water, meh not so much.

Wouldn't sweat it...every gasoline engine has it.

Yes, but it depends on how rich the engines are fun. The 1st gen FSI Audi models on the B7 as an example ran rich AF. This resulted in significant oil shearing and thus increase in oil volatility.

Newer DI engines don't have this issue, but they all run rich and can't enter ultra lean burn mode because of the sulphur content in our fuel.This is why FSI = fuel stratified injection in the EU and FSI = fuel straight injection in the US.

If our engines run ultra lean and thus reduces the issue of fuel dilution, NOX emissions go through the roof. It's also why on the new D5 A8 there is now a gpf (gasoline particulate filter). I don't know about the Q8. It's to help achieve Euro 6 emission standard
