I just changed the oil on my car today at 1200 miles. I bought a GM filter that came with a black O ring. When I removed the cartridge cover I noticed the factory O ring was blue and slightly fatter than the one that came with the GM filter I bought at a GM dealer. It also seemed like it was more dense (less pliable) then the replacement one. I tried to remove the factory O ring but it was stuck on and almost looked form fitted. I came to the conclusion that in order for me to remove it I will have to cut it off. I ended up just leaving it on in fear that the new one may not seat as well as the factory one. Is it possible that the factory switched to a non removable O ring? My car was made October 2012 as a 13 model 1.4 turbo. Thanks for any feedback on this.
