Definitions of Gasoline Grades The classification of gasoline by octane ratings. Each type of gasoline (conventional, oxygenated, and reformulated) is classified by three grades - Regular, Midgrade, and Premium. Note: Gasoline sales are reported by grade in accordance with their classification at the time of sale. In general, automotive octane requirements are lower at high altitudes. Therefore, in some areas of the United States, such as the Rocky Mountain States, the octane ratings for the gasoline grades may be 2 or more octane points lower.

Regular Gasoline: Gasoline having an antiknock index, i.e., octane rating, greater than or equal to 85 and less than 88. Note: Octane requirements may vary by altitude.

Midgrade Gasoline: Gasoline having an antiknock index, i.e., octane rating, greater than or equal to 88 and less than or equal to 90. Note: Octane requirements may vary by altitude.

Premium Gasoline: Gasoline having an antiknock index, i.e., octane rating, greater than 90. Note: Octane requirements may vary by altitude.

You must be joking now... Many cars require 91 Octane. I can't imagine a gas station in the country not offering it, let alone an entire region...

Huh?

If it's too slippery out to use cruise control on the highway, it is too slippery to be going 65 MPH.

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?

No intermediate, just 87 and 89.

We live in the great Northwest, that's the way it is, 87 and 89, a penny difference.

Howdy,

Why not send the phone number to just one person?

Surely the station would not be inconveniences by a single call.

All the best,

dbu, I think this all stems from the use of the word "super" to describe midgrade gasoline. Most of us use "super" when referring to the highest grade however it is probably more correct to call it "premium" and I am guessing that is what you know 91-93 octane gasoline as. I can believe you have a station that would charge a penney more for 89 octane gas, especially if it is an independent station where it receives its supply from a local refiner. You don't have to defend yourself or prove anything since it is obvious they won't believe you even if you did post a picture. They will accuse you of doctoring it or having the owner change the prices just for your picture.

Sure, I agree. Where the problem lies is their inability to read and decipher what I said. That is not my problem. I posted the octane numbers, but it seemed to be ignored. The station called it "super" and "regular", 89 and 87 respectively, one penny difference. It is an independent supplier. I don't know of any station in this area that sells 93 octane gas, one I know of that sells 91 octane, but that is non-oxygenated fuel for use in lawnmowers and the like and illegal to use in cars and trucks unless they are licensed antique, per state law.

Thanks for the help, but I don't think it will convince these narrow minded knot heads.

Actually, that's my main problem with his "story". I can't imagine a region ANYWHERE that doesn't have 91/93 octane fuel, as dbu states. That would mean that people like me can't drive there, as the fuel isn't high enough octane for my car...

I'm not saying there is none, I'm saying that I have not seen any except for the non-oxygenated premium fuel for lawn mowers etc and classic cars. You would have to look and plan ahead I guess.

What kind of car do you drive that requires such a high octane, Piper or Cessina maybe? I don't think you'll have any problem finding av-gas at

110 octane.

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.

A requirement of 91 Octane is fairly normal for a great variety of high performance vehicles. I drive a Civic Si. It is but one of many with such a requirement...

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.

I may have seen 89 may be called super in some areas, but not here. It's midgrade, and 91 is super.

Hi, 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 Super(92)

Remember, Europe uses a different octane rating - there are two systems. And the US averages the Research Octane and Motor Octane results to get the number we put on the pump.
