I took this sample about mid way through draining the oil (capacity 8 qts) on a hot engine. Miles are approximate but should be +-200 miles of actual. OLM at 53% remaining.
Edit: using ZL1 air filter with supposedly higher flow. Looks like no issues with filtration and it has been dusty due to construction. Typical Austin summer with 100-105 deg commutes home. Car driven in a spirited way but not redlined often.
BlackStone COMMENTS:
Universal averages for the GM LS-3 show typical wear after about 4,600 miles on the oil. Youdidn't run this sample quite that long, but wear metals still matched up nicely. We usually find higher metalsand silicon from wear in materials with engines this new, but it looks like most of that stuff has washed outby now. Silicon and insolubles were low, showing the air and oil filters are doing a good job keeping dirt andoxidized solids out of the engine. No harmful contamination was found in this sample of 5W/30. Great firstreport! Check back to build wear trends.
