You probably noticed the price at the pump is going down.
A lot of you are happy to see the price of gas just keeps dropping. Here's why.
Refiners no longer produce an unblended 87octane gasoline. In its place, they've begun using an 83/84 octane gasoline, which is blended with 10% ethanol to offer an oxygenated 87.
The 87 blended gasoline will most likely be the least expensive gas, because 83/84 octane is less expensive to refine.
Consumers will know when their local gas station is selling this new blend by the 10% ethanol added decal that must be posted on the pump by law.
Some of you might be worried that 87 oxygenated gasoline isn't safe for your car. If you are concerned about this gasoline being compatible with your vehicle, you should consult your owners manual.
40 plus states have been selling this 87 blend for close to 7 years. South Dakota is one of the last state's in the country to make the conversion
This conversion is the result of the Renewable Fuel Standards legislation that passed Congress in 2007. If you'd like to read up more on the blended 87 gasoline, we've posted a link to the South Dakota Petroleum and Propane Marketers web site.
