More recently, on 7/26, my CEL came back on and I pulled P0301 through P0304 -- misfire on all 4 cylinders. A couple of weeks later, I put in some injector cleaner. Driving home last night, I noticed the CEL had cleared itself. Glad it happened when it did because I had an appointment to bring it in tomorrow.
I change my oil religiously at 7,500 miles with 5W-30 Mobil 1 full synthetic and don't really drive my car too hard.
wayWAY too long on that garbage 'blow me up a motor' oil
and i predict that you will soon have a criticality event and need a new engine due to using that oil
give it...mmmmm...a month or 2
