Hey guys,
I've recently started overfilling at oil changes because of whats been going on with the Duratecs. After the first time I overfilled, the engine runs noticably cooler all the time.
Before it would run smack in the middle of "NORMAL". Now it rarely gets past the "N" only if i've got it at 3000k for a while. It's never been past "O".
I was thinking maybe it's a bad thermostat but was just wondering if anyone else had noticed this.
