I changed the oil in the brother-in-laws 08 cobalt that I posted last weekend and the oil filter I pulled out was a napa proselct oil filter run for a little over 11,000 miles. The oil filter has a few ruptures in the media and the media started to push into the plastic center tube. While this is not good, the napa Proselect is a good filter for this application for only $5 IF it is kept to a reasonable OCI which, 11K on GTX plus my 3qts of nextgen make up oil is too long for my liking. Hopefully I can catch him at the 3K mark to switch out the formula shell/edge mix and STP filter that I brewed up to help clean up the engine. His car is now on my maintenance schedule. This previous OCI was done at a local chain.
