All those early hondas I worked on really used up plugs, at around 25 k miles they lose about 2 + MPG in my experience, I'm talking the 90's Honda Civics and Accord, I asked the dealer at the time 1991 and he said every 15 K was recommended, he was right milage on the Accord went up over 3 , on another note unrelated has anyone here looked up the old Mobil fuel economy Run results from the 50's and 60's could be interesting.
