Hello, this is my first post here. I purchased a 2006 Subaru Impreza WRX TR with 30 miles on it. I pick it up this Friday and I will be going on a one way 375 miles roadtrip. I told my Subaru technican that I'd be driving on a 375 mile trip at highway speeds and I wanted to know if there was any reason to be concerned about it. He told me there was no engine break in period on these cars. I'm concerned because I've heard that you should teach the engine to seat the rings (whatever they are) properly by driving at various RPMs the first few hundred miles without going anywhere near redline. But by going on the roadtrip, the engine will see the same RPM for 5 1/2 hours straight. I plan on curising at 65 MPH to keep a nice balance between the RPMs and the traffic. I'm worried about the longetivy of the car. Is the Subaru tech. correct or should I worry? Thanks!
