Octane gas

RE: Octane gas
I assume you mean higher octane than regular 87?
If so, the answer is no, you won't get better performance. Honda Accords were made to perform optimally on 87 octane gas. Unless you do some engine mods that require premium (i.e. turbo), higher octane gas will not do anything. If anything, it will actually hurt your gas mileage and may cause engine damage in the long run.

RE: Octane gas
oh okay..yeah i know..but i found out that if putting premium in the 05 V-6 accords yours spose to get more HP according tohonda engineers if putting premium in the 05 V-6 accords you are spose to get 250 hp rater then 240 i dont know i looked it up but not sure i dont have the webpage right now but iwill post it later on and u can read it yourself

RE: Octane gas
The designer ofHonda's 3.0l V-6 is the one that made that statement in an interview. He said that 10 more horsepower was available when using 93 octane or better. I've posted that damned article a hundred times for those thinking I was blowing smoke and now I can't find it. With fuel prices today it wouldn't be worth it to me to cough up 20 cents or more a gallon for 10 horses at the flywheel.
This isn't the one I was looking for but:
The J30 displaces 3.0L and is a SOHCVTEC design. Output for the J30A1 was 200hp (149kW) and 195ft·lbf (264N·m) of torque. The J30A4 pushed output to 240hp (179kW) and 212ft·lbf (287N·m) using a three-way VTEC system, higher (10:1) compression ratio, and a novel exhaust manifold cast as one piece with the cylinder head. This version was on the Ward's 10 Best Engines list for 2003 and 2004. Honda provided an undocumented, but verified 10 hp boost when owners use 93 octane fuel, resulting in 250hp. The IMAhybrid version was on the list for 2005. In 2006 to mark the 30th anniversary of the Accord, Honda created the J30A5, which boosted output to 244hp (SAE Net 08/04) and 211ft·lbf (SAE Net 08/04) of torque. According to Honda, horsepower gains were achieved with extensive improvements to the airflow of the intake and exhaust systems.

RE: Octane gas
I've noticed a bit of a performance increase when i used the highest octane after months of 87...
however it's very very VERY important to notate that octate has nothing to do with performance, but rather the compression and knocking characteristics of your 'tanes (iso-octane and heptane) mixtures.. iso-octane is rated at or near 100% octane and is mixed with heptane (a 0% octane ratio) to make your octanes you see in gas stations (87, 91, 93, etc)
deflagration *should* be consistent in theory, but i personally believe that if your engine is knocking less then it should probably perform a tad better... which is why some people see this performance increase, and others don't.
i agree that 10hp isn't worth the ongoing cost.. if i could do something to the car to make the permanent for one cost, that'd be more beneficial.
