| I am surprised that no one has mentioned the artcle in the July issue of Motor Trend about the Odyssey.In the story there is a paragraph stating "The Odyssey's engine is Hondas most potent.The horsepower rating is achieved with the use of premium unleaded fuel.Regular grade fuel lowers output by just 5 horsepower and 12-feet of torque a reduction we did not notice in everyday driving".Who is going to volunteer and do a test for all of us. I know there are some chemical engineers out there that enjoy doing the calculations. |

As has been discussed before on different threads here, one real question is how much does it lower fuel economy? If it is more than 10 percent, then it is a wash based on the difference in price between regular and premium, in which case there is no economic point. I DID do a test on my 1999 BMW 328I and discovered that the reduction in fuel economy was at least equal to the redution in gas price. Thus, there was no point in using anything but premium. I'd be curious if the results track with the MDX... (Of course, this does not take in to consider what difference in performance there may be - I'm simply considering economics in this discussion...)

| The issue is not gas mileage. It has to do with the oxigenators. Do a search and you'll find plenty of discussion. |

In localities where oxygenators are required, they are required in all grades of fuel and are in equal amounts in each grade. Thus, as long as you are comparing fuels from the same area, the reformulated fuel (as they are called) has no bearing on the octane issue.
