Does anyone know how to resize the text inside the [ code ] tags?

The TBN doesn't look all that impressive after 8K miles given that ~50% of the oil was replaced during this interval.

Hello Manganese in Canadian gasoline

Wow, are Redline sulphur readings usually that high? I can't say I've noticed that before.

I just checked! Maybe it's because Blackstone doesn't check for sulphur, but WearCheck does... d'oh! And according to other WearCheck VOAs on Redline oils, that number seems to be in line with what Redline puts in... sulphonated something or other, anyone?

50% of your total oil was replaced. That is pretty high.

An RX clean may be a good idea in this engine. Free the rings up a bit hopefully.

How many miles are on the car?

Ferrari, is that the 2.8 12 valver, the 2.8 30 valver, or the VR6? How many miles on the engine?

That's a pretty small level of manganese in there actually. I've had reports where my manganese was over 100ppm!

 

[bigpaulo]

Patman, UOAs with USA gasoline usually have 0 or 1 ppm manganese

Just another thing to watch out for... that'd be a great UOA exam question!

Anyone know what's up with the sulfur?

73,000Km on the car, so the oil was put in at 60,000Km.

The engine is the 2.8L 30V V6

You may want to compare your numbers to mine. That's the Audi 2.8 V6 12v motor. OCI was 8k mi (almost 13k km) and makeup oil was 4 qts: http://tinypic.com/1tahdh

I would replace your PCV valve if you are burning that much oil.

I don't know about the 30v, but the 12v motor doesn't have a PCV valve.

I believe that the high oil consumption in some Audi and VW motors has to do with the skimpy low-tension rings. In case of the 30v, there are also plenty valve stem seals that can and eventually will go bad.
