When you pull up to the gas station, chances are you have a choice between Supreme, Premium, and Regular gas. But what is the difference between Supreme and Premium fuel? Is it really worth the extra cost? In this article, we’ll take an in-depth look at the differences between Supreme and Premium gas, exploring their chemical compositions, octane ratings, and the potential benefits of using each. We’ll also discuss the environmental impact of using each type of fuel, as well as the potential cost savings you can expect to see when you switch to either one. By the end of this article, you’ll be an expert on the differences between Supreme and Premium gas and will be able to make an informed decision on which one is best for your vehicle.
Is Supreme Gas The Same As Premium?
No, supreme gas is not the same as premium. Supreme gas is a higher-octane fuel that is designed to provide better performance and improved efficiency in high-performance engines. It has a higher octane rating than premium gas and is designed to be used in engines that require higher octane fuel to reach their optimal performance levels.
Supreme VS. Premium Gas
- Supreme and Premium gas are both higher-octane fuel blends than Regular gas. Supreme gas typically has an octane rating of 93, while Premium usually has an octane rating of 91. Both fuels contain detergents that help keep your engine clean and running smoothly.
- Supreme fuel generally contains more detergents than Premium. Additionally, Supreme fuel is typically blended with a higher percentage of ethanol than Premium fuel, which can help reduce exhaust emissions.
- When it comes to gas quality, it’s not just how good the gas smells that matters. The chemical composition of the gas you use makes a big difference in the engine performance and durability of your vehicle.
- Supreme (also known as regular) gas is the type that’s typically found at most gas stations in the United States. Supreme gas is made up of a blend of petroleum and additives that is designed to be the most cost-effective way to transport gas. Premium gas has a higher octane rating than Supreme gas and is a better choice for high-performance engines, like cars, SUVs, and boats.
- Most cars, SUVs, and boats can run on regular gas, but certain high-end models require premium gas. Premium gas has a greater concentration of the gasoline additive tetraethyl lead (TEL) than regular gas, which helps prevent engine damage from high temperatures.
Chemical Composition Of Supreme And Premium Gas
- The chemical composition of Supreme and Premium gas is what sets them apart from each other. Supreme gas contains a blend of gasoline and additives, while Premium gas contains a higher concentration of TEL as well as other additives.
- The main difference between the two fuels is the octane rating. Supreme gas has an octane rating of 87, while Premium gas has an octane rating of 91 or higher. The higher the octane rating, the more resistant the fuel is to pre-ignition (engine knock) caused by high temperatures in the combustion chamber. This helps prevent engine damage due to high temperatures, which can be especially important in high-performance engines.
- Below is a look at the chemical composition of Supreme and Premium gas, broken down by the percentage of each component. If there is a difference between the two, that is noted in the chart below Ethanol: This is a primary ingredient in every gallon of Supreme and Premium gas. There are currently no federal laws in the United States that require gas stations to use ethanol as an additive to fuel.
- Octane: This is a measurement of the resistance of the gas to detonation, which is a type of engine combustion that can cause damage to an engine. High-octane gas helps prevent damage from detonation by increasing the compression of the fuel.
- Denatured Alcohol: This is a byproduct in the refining process that is typically removed from the fuel before it reaches consumers. Most of the alcohol is removed during the refining process, leaving only small amounts that are denatured and found in Supreme and Premium gas.
Potential Benefits Of Using Supreme Or Premium Gas
- Higher octane – High-octane gas like Supreme and Premium has a higher octane rating than regular gas, which means it’s less likely to cause engine damage. Higher octane gas also helps prevent damage from detonation, so it’s a good choice for high-performance vehicles like cars, SUVs, and boats.
- Increased fuel efficiency – Higher octane gas results in less loss of energy during combustion, which means it can be used in smaller engines that typically run on regular gas. Premium and Supreme gas can also be used in larger engines that require high-octane gas. This can help you save on fuel costs and improve your gas mileage.
- Reduced emissions – Higher octane gas requires more compression, which results in higher combustion temperatures and increased emissions. Lower emissions from premium and Supreme gas mean less pollution from combustion and less damage to your engine.
Environmental Impact Of Supreme And Premium Gas
- At the end of the day, the gas you choose to fuel your vehicle has a big impact on the environment. Here’s a breakdown of the environmental impact of using Supreme and Premium gas.
- Higher octane gas like Supreme and Premium has a greater impact on the environment than regular gas due to the higher amount of denatured alcohol in the former. The greater amount of denatured alcohol in the fuel results in greater emissions during combustion and higher levels of nitrogen oxide, a harmful pollutant that contributes to smog.
- Lower emissions from premium and Supreme gas mean less pollution from combustion and less damage to your engine. This also means less wear and tear on your vehicle, which can help you save on gas and maintenance costs.
Which Type Of Gas Is Best For Your Vehicle?
- Now that you know the benefits of Supreme and Premium gas, it’s time to choose which one is best for your vehicle. Here are the key differences between Supreme and Premium gas:
- Premium gas has a higher octane rating than Supreme gas. Some high-performance vehicles such as race cars and boats require premium gas.
- Supreme gas has a higher ethanol content than Premium gas. The ethanol content of Supreme gas is typically 86.9% and Premium gas is typically 85.9%.
- Both types of gas have the same denatured alcohol content, which is small amounts of alcohol that have been denatured during the refining process.
Tips For Saving Money On Gasoline
- The most important part of switching over to a higher-octane gas like Supreme or Premium is ensuring the amount of octane is correct for your vehicle. The octane rating of your gas must match the octane rating of your engine, which is usually printed on the gas cap.
- To ensure the correct octane rating, you can either call your local gas station or use a gas analyzer. If you’re unsure about which gas to use for your vehicle, check out our guide for the best gas prices in your area. It’ll help you find the best gas price for your location, allowing you to save money on gas no matter where you live.
- Another way to save on gas is to regularly check your tires. It’s easy to forget that your tires are slowly losing air pressure and exposing the tread to air pollution and damage. Keeping your tires at proper air pressure can help protect the tread and save you money on gas.
Conclusion
When you pull up at the gas station, it’s important to pay attention to the type of fuel you’re putting into your car. Supreme and Premium gas have a higher concentration of ethanol and are designed for high-performance engines like cars, SUVs, and boats. These types of gas have a greater impact on the environment thanks to the higher concentration of denatured alcohol.
