You'll be fine as long as there isn't something on the verge of going out. I've driven my MSP as my exclusive daily driver for a year without any problems. The engine runs cool (at least mine does) and I haven't had any problem on my road trips. I used to run it from Chicago to Grand Rapids (3hrs) on a weekly basis, and I've taken it from Michigan to Oklahoma and Mississippi without a problem. There were parts of the trip from OK to MS where I actually hit like 34mpg with it.
