AAP has the Havoline synthetic oil change deal with a Driveworks filter, or for $2 extra you can upgrade to P1. As most of you know, Purolators have been suffering from quality issues lately with the media tering, but the Driveworks is Chinese. Has anybody run into any problems with Driveworks oil filters lately? DW uses Purolator's numbering system, but AFAIK they're not actually made by Puro/Mann. So, what would you guys pick? Chinese or tears? I'm leaning towards the American ripper, mainly for the textured grip. It will be replacing another P1 already on the car, which is equipped with an OLM.
