TruFuel Premixed Gas and Oil
The most popular type of gasoline is “premixed” with additives to make it taste better or increase its octane rating. These are called “trufles.” They’re sold under several brand names, including Sunoco’s Super Plus (which contains up to 80% ethanol), Valvoline’s Pure Fuel (80/20 blend of ethanol and unleaded gas) and ExxonMobil’s Ultra-Premium (70/30 mix).
There are two main types of ethanol: Ethanol monohydrate and ethyl alcohol. Monomeric forms of these substances are used in making polymers, plastics, pharmaceuticals and other products. Alcohols form when they react with water to produce carbon dioxide and hydrogen. Most fuels contain both monomers and alcohols; however, some have only one type of substance added to them.
For example, natural gas is usually made from methane gas which contains no ethanol or alcohol at all.
What makes the mixture of ingredients in premixed fuels different than those found naturally in petroleum?
The main difference is that the ethanol and alcohols are mixed together. When they do so, they combine chemically to create compounds known as hydrocarbons, which are heavier than air and therefore can’t float through the atmosphere easily. Instead, they must be burned in a combustion engine. These formulas are similar to those found in petroleum; however, they mix together when the fuel is pumped into the gas tank and have different properties from their naturally occurring counterparts.
The addition of other ingredients in the fuel that do not react with water or alcohol also affects how easily the fuel can evaporate, and how quickly it goes stale. For example, a mixture of alcohol and gasoline additives reacts differently than just alcohol alone. The additives help the mixture evaporate more easily, making it a more efficient fuel. It can also be stored longer before it goes bad, which is a problem with pure alcohol.
The major oil companies have been working for years to create different types of gasoline and diesel fuels that have the same or similar effects as biofuel. The goal is to cut down on pollution caused by burning fossil fuels without having a negative impact on the environment or increasing the country’s dependence on ethanol-based fuel.
