my car has about 100,000 miles on it. i changed all the fluids, spark plugs, and stuff, plus i used a can of engine restore, that stuff works. is there any liquid type stuff (like fuel injector cleaner etc...) that i can put in my engine that would help get it closer to its old self?

 

I've been told that additives generally will not help Honda engines much, if at all.

My engine is at 154k and it's exactly like its old self...just as powerful, smooth and rev happy as before. All I need to do is adjust the valves. I'm curious as to exactly what is wrong with yours.

 

nothing is wrong, i just figured all engines will lose some power do to build-up etc... if they have over 100,000 miles on them.

 

They Dont Help Honda Engines. There Is No Reason To Use Them In Hondas Eyes.

 

Not necessarily true. Depends on how lucky you are, how it's been driven and how well it's been maintained. If you really want to know, do a compression check and put it on a dyno.

Like I said, my engine is perfect at 155k...I had it up to 135 within the last 5k miles and since I've switched to synthetic she's stopped burning oil.

 

If you're looking for stuff to do, how about a new timing belt??

 

Yeah, that's a bitch and a half to change. But if you don't change it and it snaps, you're screwed. Change that and the water pump together...I slacked off and did mine at 135k miles. The belt still looked like new.

 

Not that it matters, but will getting a new timing belt increase performance any?

 

No but it will make sure u keep your engine.

 

It's called prevantative maintenance.
