Hi Mike. I'm not sure about my '04 Accord LX,
but I'm pretty certain my '92 Accord is supposed to
have 87 regular. Maybe it was just a subjective
impression on my part to believe that the 91 octane
extended the engine life, but in any event your comments
are food for thought. Many thanks. - Paul

Hi Steve: Thanks for your input on the status of your own '91
Accord. You really didn't need to get sarcastic. I was just
stating an impression and asking an honest question. - Paul
