Three days now with a 2010 Forester Premium Trim Level . Not my first rodeo. Traded in a 2002 Outback with 160,000 miles. Going to run Dino oil until the second oil change-about 5000 miles and then go with Mobil 1. Going to go the synthetic route on the Trans and Diffs when they are due for service as well. I do about 25-30 k miles a year. Like the vehicle.
