Aside from my usual oil changes, here are other major maintenance and
repair issues for me:

1) All new belts, water pump (146,800)
2) New ignition wires and other ignition stuff (148,000)
3) Spark plugs regularly (42.5k, 80k, 117k, 148k- with other ignition
issues)
4) New battery (6-1/2 years 130,000 miles)
5) Replaced muffler two times

I saw a posting saying 270,000 miles at the time he posted. How long can
a Honda Civic actually go without rebuilding the engine?

 

I got 220,000 on original engine before it got totalled.
After 200K I vowed to exchange it should
a repair exceed $500. Always seemded to require
about $1000 -$1500 of annual work in its elder
years, but never a major incident that would say "junk it".
(Half of the amount was a 30K major maintenance
and wear-and-tear things each year.)

Incidentally, the car was so old, it lacked air bags
which would have reduced the accident injuries.
Several safety features are routine on newer Hondas.
But the car that crossed the median and front ended
me was a larger Kia mini-van and not everyone in that one
lived. So I cant complain too much.
