Comments:
Wear looks good in the first sample from your Impreza. Universal averages for the 2.5L are
based on an oil run of about 4,000 miles. That's exactly how long your oil was run and we are happy to see
all wear reading at or better than average. Lead was excellent at 0 ppm, and this shows virtually no wear
from the rod and main bearings. No harmful fuel dilution or anti-freeze was found and the viscosity of the oil
read in the 5W/30 range. We see no signs of any obvious problems developing in this data and a longer oil
run should be fine. Try going up to 6,000 miles

Oil filter was Champion Labs re branded STP filter from Auto Zone
