06' Audi A4 11k miles, Castrol GC 0w-40

[smonska]

Mostly highway miles. 5qts of makeup oil added over 11k miles (has burned a quart every 2k since motor was new).

Iron trending up. I had the HPFP lifter and exhaust cam replaced at 160k. They are a known issue with these engines, they wear and start short stroking the fuel pump and you get low fuel pressure codes. I wonder if it is "breaking in" still?

Previous oil change was GC 0w-30, and the ones from 2010 were Rotella T6 5W-40

The wear metals are from the cam breaking in so I wouldn't worry. It'll settle down.

You're joking, right?
I'd go back to using the T6

No he's not kidding. That is exactly what is going to happen. New metal parts in any engine has to throw metal until the break-in period ( for that new metal) has ended.

Yes, these engines have wrong piston rings tension. Your catalyst is SO 'happy"...

 

[Spector]

5 quarts of make up oil, current and previous OCI. is that correct? With that much make up oil surprised the numbers for iron are that high?? Also, make up oil went from 1.5 to 5 quarts? Something is amiss?

The ferrous atoms that come from wear don't disappear just because new oil is added.

I would try adding 2 bottles of "Rislone Engine Repair" with the next oil change and hopefully you would not have to top up 5 qt of oil!

Fuel dilution as well.

I think Rislone is Bardahl here in the US. I may be wrong.

Rislone and Bardahl are two completely separate companies.
