If your car is very hot (mine is)... there is probably a marketHHAHA who would buy used oil.

Top off with a higher viscosity oil.
Your piston soak likely did nothing much. Most products don't dissolve carbon, and clearly yours did not dissolve any. Consider sourcing an effective product and performing another piston soak prior to the next oil change.
We even do piston soaks on aircraft engines. It does remove carbon and reduce ring sticking.
Thanks, that gives some comfort. So you dont think hard carbon broke off and scored a cilinderwall? Any advise in what solution to use. B12 is not available in the NetherlandsTop off with a higher viscosity oil.

$81 a bottle? Jeez, that's probably more than a set of new rings. And how does something added to the fuel help with the rings?32 OZ YAMALUBE RING FREE PLUS E-10 FUEL ADDITIVE ACC-RNGFR-PL-32

This and several short interval oil changes. Done.

Trav is one of the most knowledgeable posters on this forum. Do what he suggests.These engines work best with a heavier oil a 0w40 is what I have used and never had any issues. Castrol Euro 0w40 would be my go to for a VW/Audi. I had one VW that never used any measurable oil over a full OCI for years then I tried a popular brand of Euro 0w30 (not Mobil or Castrol) it turned into an oil drinking sow, back to the Castrol 0w40 and it went back to normal, engine compression remained normal.
No. Even hard carbon has a Rockwell hardness of 0 (a joke of course, the scale does not go low enough to measure carbon combustion chamber deposits), the rings are hard chrome faced with a hardness of about 70. Even soft pure cast iron has a hardness of 40. Not sure what the bores are, but they would have to be made of something stupidly soft to be damaged by carbon bits.So you don't think hard carbon broke off and scored a cylinder wall?
Don't forget what most call "carbon" has a lot of "ash" in it, which can contains: Boron, Molybdenum, Calcium and Zinc in some compound form - possibly oxidised. Worst I've witness happened - and we havent done this much with a followup teardown - was some piston top flakes migrating and sticking a valve open or flouling a plug. We would use the "Stream clean" using water and methanol and sometimes hydrogen peroxide.No. Even hard carbon has a Rockwell hardness of 0 (a joke of course, the scale does not go low enough to measure carbon combustion chamber deposits), the rings are hard chrome faced with a hardness of about 70.

B12 contains a large percentage of toluene. Here in the US we can buy toluene in hardware and paint stores. If it’s available to you I would try toluene, possibly mixed with some acetone or methyl ethyl ketone.Thanks, that gives some comfort.

I could have written this post if i wasnt the TS. Off course i was burning oil. All Audi engines do. But i was not measuring it. Now i do and maybe a already was almost at the threshold value. In combination with a thinner oil maybe it is nothing. I came here for a little peace of mind and i found it. I will change the oil for 5w40 and have to wait to be sure....Your assumption that the engine “uses no oil” was flawed. The oil level sensor uses a range, of say 75-90mm level to say, “OK”. Then, at 74, it says “Low”. That’s how they work. So, your engine could very easily have burned a liter, or more, in the first thousand miles.
Change the oil to get rid of this solvent. No more piston soaks, because it clearly didn’t help. Use a good XW40 oil this time.
I’d change it to one that has the proper Audi/VW approval. That will include the correct grade.I could have written this post if i wasnt the TS. Off course i was burning oil. All Audi engines do.

And $6k to pull the engine, disassemble, probably machine work, gaskets, and etc. by a shop to install those low quality rings you are referring to. You don’t know the carbon issues in outboard boat motors (2 & 4 stroke)?$81 a bottle? Jeez, that's probably more than a set of new rings. And how does something added to the fuel help with the rings?
