Avg to date is about 5% better, avg cost for premium is about 3-4% more.

What kind of driving were you doing when you got those best and worst mileage numbers for one tank? Average it out over a couple of months and you'll be sorely disappointed in yourself for wasting that money.

My gas mileage goes from 10.7 to 10.5 in the city switching from premium to regular. My vehicle is SC and requires higher octane. Can't say that I see a big difference in power. However it seems to start easier on premium when cold.

Has anyone else ever noticed that they alternate the positions of premium gas at the pumps?

On one pump it will be 87-89-92 then the other pump 92-89-87.

The only reason I can figure is that they know people wanting 92 will purposely select 92 but that other people who don't care might just hit the left button(left is usually lower in most things in our society) and not notice until too late that it is the more expensive gas.

you know, fellas, of all the places in the world it doesn't make sense to get called a tool of the oil companies, i think an H2 board might be at the top of the list. (forgot to add taht last night)

ethanol has 100,000 BTU's per gallon, gasoline 150,000. 10% ethanol in gas 145,000, or a bit more than 3% less, about in line with the price diff, and not far from my observed 5% diff in mileage. Same BTU's per dollar, seems reasonable to me.

And finally, i'm nearly sure that what gas i opt to fill my truck won't cause you guys bodily harm, and i'm so sure of that that i'm willing to accept liability unconditionally.

I do know that in most states in 2004, E10 only accounted for 10% of gas sales, so at least in 2004 all Regular was not E10. Either way in most states it must clearly labelled that you are getting E10 or any blend over 1% for that matter.

well up here, some pumps have "non-oxygenated gas" labels next to premium (oxygenated gas means ethanol or other additives, which i'm sure you know), and some pumps don't.

That and conversations lead me to believe that non-premium has ethanol.

Happy labor day, Phil & everybody.

Non oxygenated gas will obviously have a slightly better performance, around 2-3% as you stated, but that hardly makes up for the 10% difference in price.

The majority of us are offerred either all grades with something added, or all grades with nothing added, soit is kind of moot point anyway.

i have never seen premium for 10% higher price. typically a nickel, a dime at most, higher than other things (or about 2-3%).

Whatever the case, i can't imagine why anybody would care what gas another puts in his/her vehicle. ?

MTBE: in some states.

Bad for groundwater --- makes it easy for carcinogens like benzene to leach into the water supply.
