Ok, but seems to me there was a few years ago, octane number varied
according to ethanol mix or not, I just don't remember. Nobody that I
know uses 91 octane. If there was 20 cents difference between reg and
premium or as my favorite station calls it "super" then I would buy
regular, but it's not. When I visit the next state over their fuel
prices tend to be higher especially along the interstate. I always buy
regular because of the price difference.
It is possible a small town in the boondocks with low population to not
have what the rest of us have become accustomed to. I live in SE
Virginia and when travelling across the state I see many small towns
with gas stations I do not recognize. Merchants tend to stock what
their clientele use. For those of us who are used to tons of choices
life in a small town can be quite an adjustment.
Actually, I was in Colorado a couple of weeks ago, and all the gas there
seemed to be a couple of points lower in octane than what I'm used to in
Texas. I don't know why -- something to do with the altitude, maybe? Alas, I
have no photos to support my assertion.
I just came back from Baltic cruise. Over there in Northern europe gas
has two grade, Octane 92 or 95. Lot of small peppy cars on the street
which my need higher Octane gasoline. Worst price was in Denmark, over
3.00 per liter. Up here in Canada it's Regular(87), Premium(89) and
Actually, in at least some modern cars, premium gas can improve
mileage and performance. Cars with knock sensors will advance the
timing with higher octane fuel. The more advanced timing will improve
fuel economy and performance. I know that at least some Honda engines
do this, not sure about Toyota. The improvement is small and wouldn't
justify the extra 20 cents.
It is hard to believe that anybody is selling Premium for a penny more
than regular. How is the intermediate grade priced?
Supposedly the ethanol is in there to "oxygenate" the fuel (ethanol contains
oxygen, gasoline doesn't) in order to make it burn cleaner. Refiners used to
add something called MTBE to gas for this purpose, but the MTBE ended up
leaking out of tanks and contaminating groundwater, hence the switch.
Ethanol does have a lower energy density than gasoline, so you can expect to
see slightly poorer mileage with fuel containing ethanol than with
If I could get "premium" for a penny more per gallon than regular, I'd use
premium too. In more than 35 years of driving, I've never seen that.
I'd love to have a gas station that only charges 1 cent more for
super, as my Audi uses that (although I do mix in a tank of 'plus' on
a regular basis. I can't notice much difference in performance or
My Odyssey EX averages just under 17 mpg in town and I have gotten as
high as 25 on the highway - the usual is 23. That's generally with a
pretty loaded car (5 people plus dog and luggage) and the cruise set
for 76-ish. I'm happy with that. Our old Ford Crapstar used to get 15
in town, 20 on the highway and was a piece of shit besides. ;-)
'07 Ody EX
Central NJ USA
I just talked to my buddy who has a 08 Ody which uses only three
cylinders while on longer trips and he said he gets 32.5 MPG but that
was using S.D. premium gas, wind at back and driving the speed limit, 65
mph with a steady foot. Sadly, today so many people have a very heavy
foot, I see it all the time in city traffic and on the long highway
trips. If drivers would learn to drive like they have an egg under the
gas pedal and hold the speed down to 65 or so, they would see much
better gas mileage, also keep those tires inflated.
