Road trip with 150000 miles?

I have a Honda civic 2002 and it has about 150k miles on it and I'm driving from california to oregon and I was wondering. Will my car break down? It doesn't have any problems but it is a lot of miles so if any one has any advice?

If the timing belt has been changed according to the service manual.
If your oil and water levels are correct.
If your oil and filters have been changed at prescribed intervals.
If the car has been maintained and serviced regularly.
If you don't red line it all the way but drive sympathetically

There's a god chance you'll make it. But cars are just a lot of mechanical parts lumped together and things occasionally break.

Good idea to just check on everything maintenance related, checking water, engine oil, transmission fluid, and I would also encourage you to check brakes and tires. I had a friend drive his old Honda Civic up from L.A. To San Francisco and he discovered he needed new brakes when he was driving the hilly streets of S.F. Of course it is more stressful if you need to stop for repairs in the middle of a trip, so just figure out what regular maintenance and repairs are needed before you go. And of course pay attention to the details like engine temperature as you are driving, and if the engine is overheating pull off and check it. You may like to carry some extra engine oil, radiator fluid and whatnot along just in case you discover it is low on something along the way. Older engines may just burn a little oil, it happens as the tollerances get wider with wear and age.

Take it to a shop for them to go through the car just to be on the safe side

Try and find out if and when the timing belt was changed, honda recommends they be changed every 90,000 kilometers.other wise you should be good to go.you, re driving one of the most reliable cars on the planet.150,000 is nothing for a honda. Do get the timing belt checked because if it breaks on you it willwipe your engine out especially if its a v-tech engine.
