It's another good report for your Audi. This oil was run just under 6,000 miles, but you couldn't tell it by looking at wear. All wear either held steady or improved over what we found last time and that is an excellent sign that no problems are developing. We did fine a trace of fuel, though that's not what we would consider a problem level and it should take care of itself next time. The viscosity was again slightly low, but a little better than what we have been seeing. The TBN was strong at 4.5, so active additive held up nicely. Try 8,000 miles next oil.
