Ron: Universal averages show typical wear levels for a GL1800 after about 4,500 miles on the oil. Your oil run lasted 4,223 miles and wear metals read higher than average, but this is mostly due to lingering wear-in. The viscosity for this oil read normally as 10W30. There was no fuel, water or antifreeze present. Silicon read at 13 ppm, but 4ppm of this is from an additive in the oil. So, the true silicon reading is 9 ppm, which shows air filtration was good. Oil filtration also looked good. All in all, this was a nice first report
