Looking at purchasing a 07 chn613 with 407,000 miles, and has a 480 hp e7 engine. Just been hesitant on any 07 engine and wondered about Macks good and bad on engines. Thanks

If you stay around 105,500 lbs or lower you should be fine for the most part. If you work those engines too hard you tend to have injector issues.
