injectors cleaning
 

Hello,

I was chatting with a coworker who told me that all cars need cleaning
of the injectors every 30 to 60k. Heck, I have a 98 Civic and a 2000
Civic and, to me, they run perfectly well with about 100k miles on
them.

Isn't it that if anything goes wrong with the engine (including
clogged injectors), then the mileage will drop? Both cars exhibited a
mileage increase from day zero to up to about 3 years of use, then
stabilized to about 34-36mpg for 50/50 city/highway driving.

So, is it true that sooner or later the servicing will have to include
injector cleaning or is my mate bs-ing?

Thanks
