This is my first UOA done on my wife's car. The car has been running the Shell Rotella T Synthetic 5W-40 CI+ for the past 6 oil changes, each around 3500 miles. Currently trying out the CJ-4 formulation and will get another UOA when it comes out.
The high fuel is likely due to pulling it out of the garage and driving it down to the shop and letting it idle for a few minutes without getting up to temperature before taking the sample.
There are just over 70K miles on the engine, the engine has no modifications other than a K&N panel filter.
