Bought new by me in '09, it's been a daily driver and commuter (weather permitting) for almost 10-years now. Granted - for several years, I only worked 1-mile from my house. It's had a steady diet of Rotella T6 with 1,000 mile oil changes it's whole life. Engine has never been touched other than routine maintenance (belts, rollers, etc.)
Well - finally hit 15,000 miles this morning.
(The ODO rolled over at 9999.9, since it has a limited number of digits.)
