I have a 2012 3.7 v6 that I purchased brand new. Her name is Black Betty. She has 162,000 miles on her, and the only issue was a water pump that went out at about 55k miles. Other than that, this thing runs like brand new. I have never even had to replace the brake pads. It's a manual, all highway miles. What kind of mileage do you think I can ultimately get out of this engine?

 

Highway miles are the least stressful on a car. With proper maintenance, it could last over 500k miles.
