Does anyone know how crucial the engine break-in period is?? I know the manual says that you shouldn't go higher than 50 for the first 100 miles or so and then not over 55 for the next 800. Well, in LA, you really can't go to the market w/o hoppin' on the freeway and it's tough to stay within those speeds while on them. I picked up my black LTD about 3 weeks ago and have about 1,100 miles on it. The night I drove it home from the dealership, I had it goin' about 70 and have since been anywhere from 70-80 on the freeways. The engine seems fine and like it was the night I drove it home, but I wonder if this maybe affects the long-term reliability of the engine. The dealership said that it was more important not to have it goin' the same speed for long periods of time, which i've managed to do. Any thought on this would be really appreciated. Thanks. Also...just fyi...this is my first truck/suv and I have to say that it's the BEST vehicle i've EVER owned!!! I can't seem to get enough of it and find i'm making up excuses to go driving around in it. I think Jeep's got a real winner here!!
