I'm new to this Forum since I recently bought a 2006 Accord Coupe V6/6M even thought I used to have a Full Blown Turbo D16Z6 Civic Coupe EX that I sold about 4 years ago.
To the point, I became very curious about the performance of my car with regular or premium gas and checked out this forum and found two groups.
1-Those who believe on the statement that premium gas yield more power on cars that HAVE A KNOCK SENSOR like ours.
2-Those that think that it is sort of a fantasy or a placebo effect (Haters of the premium gas statement)
Interestingly I found some information regarding the claims of an Honda technician(That I believe is a Round Up/Proficient Engineer) named Asaki Yasuaki that premium gas yield an additional 10 HP. Some said that this guy was full of it and it was BS. Based on that, I took my time and went out for more factual data on this topic and found out that this guy Yasuaki Asaki, have a Patent on his name US 6947828B2 assigned to Honda Motor Co. LTD titled "Knock Control System for Internal Combustion Engines". I think this guy knows what he is talking about when he said that premium gas will free up some power on our engines.
The Patent information can be accessed with this link "http://www.wikipatents.com/US-Patent-6947828/knock-control-system-for-internal-combustion-engine/Page-21". More interesting, if you read paragraph #5 on page 21 it clearly explain the adjustment done by the ECU to the ignition timing based on the knock sensor signal. On a 10.0:1 compression ratio engine that is conservatively tuned for 87 Octane, a timing advance with higher octane gas will definitively yield additional power.
Food for thought...
