There we go. Getting personal, no need for that. What I've shown is a willingness to learn, take criticism, admit when I was wrong. Am I running a polling organization??? Not at all, don't know what made you say that.
Am I a top tribologist??? Lol, heck no.
Have I chatted with members that left due to hypocrisy??? Yes, and often referred them back and gave then a list of people they should listen to as I've been browsing for the past 10 or so years.
I don't know why you would make those comments. Totally confused.
Thank you for the conversation fellas. Thank you for being cordial.
If you guys would like to discuss the subjects in this thread further, let's take it to pm, I'd l9ve to learn more.
Don't want to offend respected members or donors by asking questions or pointing out the obvious. It seems their reach is quite long as to stays on this site or who goes. Quite a bit further than facts.
Thank you.

Is that a same guy who co-authored book called Synthetic lubricants and high performance functional fluids? I read somewhere that 3rd edition of this book is at works. BTW, very good book. He also worked at Infineum for some time I believe or was he only a consultant?

Yeah, I have a whole thread on him:
Leslie R. Rudnick
Rudnick was one of the key players behind the development of novel base oil blends, such as integrating AN's with PAO and POE. This approach was developed to overcome the issues with poor solubility and seal swell inherent with the use of PAO while also working to reduce the surface competition...
bobistheoilguy.com
And yes, he worked at XOM/Infineum back in the Tri-syn days.
The book you referenced:
Synthetic Lubricants And High- Performance Functional Fluids, Revised And Expanded
Offers state-of-the-art information on all the major synthetic fluids, describing established products as well as highly promising experimental fluids with commercial potential. This second edition contains chapters on polyinternalolefins, polymer esters, refrigeration lubes, polyphenyl ethers...

As @MolaKule stated:
MolaKule said:I would say Les is the "Godfather" of lubricant knowledge and formulating as evidenced by his many papers and the editing of so many textbooks on oils and lubrication.

OK, thank you for clearing that up. And you are quite welcome.
OP, let us know what happened to oil consumption.
Thanks Edy. Still working on it. Hoping to get it into an Audi shop to run a compression test, look at PCV valve etc.
I'm thinking the first step I would take would be to replace oil separator and possibly thermostat. Have run the car for about 125 miles since topping off and it is down almost a one quarter quart on the digital dipstick.

At that rate, do you see smoke out the tailpipe?? That's a considerable amount of oil to be burning.
I know it's hard to see under it with all the underbody cladding, but are you absolutely sure you're not leaking any oil??
Even though I've fixed the oil drinking issue on numerous 3.0t engines by changing the aos, I really would hate to be wrong and the fix not work for you and cause more expensive damage like bad cats.
Did you talk to the dealer and check your local buying laws??? Depending on your location and price you paid, the dealer might be obligated to fix it or take it back.
Bright light at the end of this, when it's fixed, that car will be amazing to drive.

Thanks Vermess. The tail pipe seems to be extremely clean. I am really a rookie with all this and trying to get up to speed. But I don't seem to see any white or blue smoke.
I'm waiting on a UV flashlight as someone said the Liqui Moly has dye in it. I know it's best for an experienced mechanic to look at it but before they take another look would I possibly see much popping the hood and shining UV light in there?
The 5-40 new generation has the dye that you can see. It pours out green.
And yes, you will be able to see the dye.
As I said. Check local laws before paying anymore money to anyone. Dealer might be obligated to fix it.
Thanks. I'm looking into that now.

Idle car for 5-10 minutes. Let someone press gas pedal and see whether you have any whitish smoke. Those would be valve stems.
At 1/4 at 125 miles that is huge amount of oil. I am leaning toward some leak or valve stems or piston rings.
I would contact seller tomorrow and inform them. Also, send them an email with description so you have record that you informed them about problem.
If you have leak of that magnitude, it has to show at floor somewhere.

who ever buys these cars is nuts and deserves what they get
No. Best thing to do is get under it, then follow the trail upwards, if there is one.
Valve stems or piston rings at 76k on a 3.0t??? Never seen it before .
76k is prime mileage for a aos to fail.
I still say the op contacts the dealer. That aos replace is such a easy job, they might do it themselves even if not required to keep a customer happy.
Anything can happen to any engine.
Wow. Talk about a passive aggressive tone.
