Re: Spark Plug Question
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 On Fri, 26 Nov 2004 06:33:56 -0700, "Michael Pardee" <michaeltnull@cybertrails.com> wrote: > >"Paul" <Paul@Home.com> wrote in message >news:d6cdq0hkij73fumjd02lqh0l6q7jvr87di@4ax.com.. . >> >> How about if I like to use high octane fuel?

Re: Spark Plug Question
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 On Fri, 26 Nov 2004 06:25:19 -0500, "Steve Bigelow" <stevebigelowXXX@rogers.com> wrote: > >"Paul" <Paul@Home.com> wrote in message >news:d6cdq0hkij73fumjd02lqh0l6q7jvr87di@4ax.com.. . >> >> How about if I like to use high octane fuel?
