Silver has also mentioned that fresh tanks of gas are more fuel efficient as stuff hasn't gotten a chance to separate. He'll know more, but I think as the gas gets older in the tank, the MPGs get worse. So unless you're doing the same route everyday and filling up in the same intervals, the results will likely vary even if you use the same brand.
Thanks. Learned something today. Didn't realize the R18 needed more than 87. The manual says 87 or higher. There's an official hint from Honda. How long does it take the ecu to learn a different tank of higher octane fuel? Hate to be negative but we will prolly be raped on price for the higher octane when it likely only costs the suppliers a nickel a gallon or so. Vote this bastard in.

yeah, pretty much the same route everyday. 36 miles round trip from home to work. granted, it's not EXACTLY the same since i have to consider going to town, and some other menial trips. but actually those are minor. i figure it won't be accurate, but at least it will give me a roundabout idea on which brand gives me a better MPG. as roudcourse mentioned, we are prolly gonna get raped with the price here soon (summer), any help i can get to squeeze my gas money would be alright, lol.as far as what The Guru (silver2coupe) mentioned, i did notice that the gas degrade the longer it stays in the tank. the last 150 miles seems to peter out a bit.another thing i forgot to mention; the mileage i've been getting above are more on the conservative side, meaning, i'm going by the iMid, which, as we all know is not as accurate as calculating it (mileage travelled divided by gas used,). on the valero fill up, using the calculation method, my MPG was actually 38.5! not too shabby, really...
Isn't it not recommended to overfill the tank?
The odometer's reading will vary over the lifetime of the tire. When the tire gets worn down and the diameter gets smaller, the MPGs will start calculating higher because the car thinks you're going more miles due to more tire revolutions.
As for measuring the gas, I think that each individual tank will vary based on when the pump shots off, but I would think that over time the variations average out, making the total amount of gas used over the lifetime of the car fairly accurate. It's just hard to verify the accuracy of a single fillup without more sophisticated equipment.
