Dont put anything in your Accord except 87 octane, unless your hybrid/turbo/nitrious. Those of you that put a higher grade of fuel are wasting your money. More importantly put in a higher quality fuel. ie Shell, Chevron, 76, and Mobil.
There have been some dynos over at v6performance.net and some time slips done by the same person with premium and regular and the premium came out to give a 10 hp/tq increase, so the honda engineer in the USA today article was telling the truth.
So if you want some added power use 93 octane.
