I would be interested in a dyno run on an 03- 07 model 2.4l with regular vs midgrade vs premium fuel to see what (if any) differences, positive or negative, were noted.
I recall reading that the Honda engineer that developed the 3.0l V-6 said it would develop 10 more horsepower (at the crank I assume) on premium. What about the the 4 holer? If I read the article correctly the V-6 "brain" is sophisticated enough to realize the difference in octane but the four banger is not. Thoughts on this folks?
