IMHO, you ran your oil to long. I am not familiar with wear metal limits on a gasoline engine, but your numbers in the first analysis were to high compared to what we normally see in diesel engines. I would change the oil and filter and send oil samples every 2500 miles to get a trend. when the wear metals begin to climb by 20% or more its my opnion that the oil is breaking down and needs to be changed
