As you can see this Audi 2.8 V6 12 valve motor is using some oil these days. One quart every 1k miles is generally not unusual for this type engine, and I'm "okay" with the 0.5 qt/1k mile oil consumption. Oil consumption is largely dependent on how I drive.
This oil was in the vehicle for almost exactly one year, and although I have done 10k mile OCIs since the car hit 50k miles, I was concerned about this not VW502 approved Mobil oil and wanted to have it tested.
As some of you may know, I used M1 0W-40 for only a few thousand miles because the engine was awfully loud at idle when hot. It's nice and quiet with the 5W-40.
My driving style is sporty and I redline the motor several times a day. However, I haven't been driving much during the past year, and I drive now more city than I used to. Half of those 8k miles are probably city driving, the rest is coastal highway and some freeway.
Please keep in mind that I added 4 quarts of oil during the past 8k miles. The report states I did not change the oil, but I did it anyway after seeing how dark the sample looked.
I paid for the Dyson analysis, but haven't heard from Terry yet. Maybe he can add a comment here.
Please, anybody feel free to comment, expecially because the art of UOA interpretation eludes me.
