I have a 1991 Accord EX with 290k miles on it, and I am debating whether to seafoam it or not because of its high mileage.
What are your thoughts?

 

Is it having any running problems?

 

If its never been done before. Do a little bit at a time.

 

problems? slow throttle response, and compared to 5 years ago, its accelleration seems much slower.

by little at a time do you mean pour into brake booster hoze extra slowly, or dont use the complete 1/3 can at once?

 

dont use a 1/3 all at once. You can put a full can in your gas tank.

 

what does it mean to "seafoam" your car???

 

Sea foam is an engine cleaner that works really well. its petroleum based so anyway you can get it into your engine it will burn. It works well to remove carbon.
