The short answer to this question is no. Federal regulations that require the increased use of renewable fuels (Renewable Fuels Standard or RFS) and improvements in vehicle fuel economy (Corporate Average Fleet Economy or CAFE) have spurred an examination of mid-level ethanol blends and their potential to make the light duty fleet more efficient. The disadvantages of ethanol-laced fuels are most prevalent when stored inside your gas tank over longer periods of time. In general, infrastructure upgrades for E85 fueling represent a much more significant cost to individual retail gas station owners than mid-level blends containing up to 25 percent ethanol. This one short ride influenced my every decision in terms of the bikes I want to own. The fuel blend is provided by blending an unleaded aviation gasoline base fuel which may include iso-octane and iso-pentane, and an effective amount of a selected alkyl benzene to improve the functional engine performance to avoid harmful detonation sufficient to meet or exceed selected standards for detonation performance requirements in full scale aircraft . But it is important to note that an engines octane rating can change over time. However, it does not follow that this makes all gasoline the same. 1736) to extend a fuel volatility waiver to blends higher than E10 is passed, E15 may be offered at an increasing number of retail gas stations. Additionally, 80 percent of the existing fleet is able to use an E15 blend. Have you ever wondered, is higher octane fuel better for your engine? The short answer is no. There are three different types of octane ratings or grades that you might see in every gas station. One widespread misconception is that using premium or super-grade gas will increase your vehicle's performance and mileage. Running high octane in a low octane engine won't hurt the engine, but will hurt your pocketbook. If you hear knocking, youre likely using the wrong octane for your car. While there are numerous details to consider for individual station owners, including infrastructure compatibility and price, 17.4 million FlexFuel Vehicles that can use a high-octane, mid-level ethanol blend are already on the road today. Today, there are 17.4 million FlexFuel Vehicles (FFVs) on the road. It has more harmful emissions. The octane rating is a measure of a fuels ability to avoid knock. There are two biofuel categories: total renewable fuels (which include corn ethanol) and advanced biofuels, which include biomass-based biodiesel, cellulosic and agricultural waste-derived biofuels, and other advanced biofuels. Higher octane fuel doesn't have to do anything with the engine's performance. It depends. An E15 fuel blend demonstrated improved efficiency and acceleration performance in a conventional GDI engine, compared to neat gasoline (E0). Sometimes saving a couple of cents helps you save a ton if you think about it long term. Depending on your engine, you may need to use high-octane fuel. Otherwise, the vehicles performance and engines power output will be affected too. The manufacturers and sellers of premium gas appear to be the largest winners in this situation. Note that some areas in Europe might have different octane rating grouping. The use of high octane fuel varies depending on your engine, and most regular engines do not need it. Probably have witnessed your friends using high-octane fuel. Youve probably seen your friends use high-octane fuel. Currently, it is unclear what overall pricing strategy would be used in the widespread deployment of a mid-level blend, but without providing savings to consumers, it is difficult to market fuels directly to consumers on a cost-basis. Your email address will not be published. It might be outdated or ideologically biased. For example, some people still think that the higher the octane level, the better the fuel. So, buying it will be a waste of money unless your engine requires a higher octane gas. However, it's becoming increasingly uncommon since fuel injectors became the norm in the 1980s. In fact, it could even harm both your car and the environment, since more unburned gas will get into the emissions system and interfere with its ability to prevent noxious discharge. In this case, you will need to resort to a high octane fuel. Passed in 2005, the RFS sets blending requirements of renewable fuels in the transportation fuel supply and as such is the primary driver of domestic biofuels production in the United States. If your car is designed to run on 91-octane, use 91-octane because using 97 wont really make any difference at all. There is no accurate number or octane grading that you should put all the time. The octane value of gasoline does not represent the energy it contains. You should always follow the octane rating on that. (202) 204-5244 fax, info@eesi.org As we highlighted before, command octane rating doesn't improve your engine's performance. More than 95 percent of the gasoline sold in the United States today contains ten percent ethanol (E10). List of Cons of Ethanol Free Gas 1. It can be obtained from both natural and manufacturing methods. If your engine requires an 87 and you fill it up with a 93, then theres no harm done. In addition, because it is an oxygenate, MTBE helps gasoline more fully combust, which increases performance and . So, the higher your fuels octane is, the more resistant your engine is to knocking. Now, lets say you need to use high-octane gas because its a requirement for your car; well then, youre in hot soup. (7) Since less fuel. The figure, on the other hand, solely shows how well gas can withstand premature detonation in an engine. Cash Cars Buyer is one of the top-rated car removal companies in the nation that guarantees to pay you the top dollars and provide you with free towing despite your living location around the united states. -Ethanol, isobutanol, high-octane hydrocarbons Multiple octane levels. Reality Check! Before we dig into the details about is higher octane fuel better for your engine, we must have a good understanding of the octane rating and what exactly it means. These advantages include: High-performance vehicles have been proven to work better when fed with high octane fuel. While mid-level ethanol blends do require some changes to the current gasoline infrastructure, the challenges may be overstated. However, there are some situations where if you're driving an older car, your mechanic might ask you to use a higher-octane rating level because of some problems related to engine knocking or rattling noises that are happening in your old engine. Ethanol is a renewable fuel sourced from corn as well as other agricultural feedstocks and organic wastes. There are plenty of branches around the nation, and it's been in business for decades since the 1980s, and it's one of the top gas stations in the nation. Youll find that premium gas is often 15-20 cents higher per gallon than regular gas. Using GREET, scientists from ANL estimate that a nation-wide E25 blend with a 5 percent fuel economy gain could reduce the GHG intensity of the transportation sector between 5 to 9 percent, a significant reduction. So, instead of risking it, its better to use high-octane fuel on a high-performance vehicle. Testing a blend of E17 in new and used Underwriters Laboratory refueling equipment, NREL found 56 percent of the tested equipment was compatible. Octane, added to your fuel, in the right amounts, will prevent knocking. You've probably seen this gas station in many commercials considering the popularity. Various components of lifecycle greenhouse gas emissions are calculated by EPA for the Renewable Fuel Standard using several models, including the Greenhouse gases, Regulated Emissions, and Energy use in Transportation Model (known as GREET) developed by scientists at Argonne National Laboratory. Octane rating is the measure of a fuel's ability to resist "knocking" or "pinging" during combustion, caused by the air/fuel mixture detonating prematurely in the engine. An octane booster, for example, will enhance the octane rating of a vehicle and reduce the risk of your diesel pre-igniting . When we talk about the disadvantages of high octane fuel. Only a very small percentage of (mostly premium) automobiles benefit from high-octane fuel. So, if possible, its better to save your money in this case. When a gas produces less greenhouse gas, its better for the environment because it causes lower air pollution. Higher octane fuel doesn't have to do anything with the engine's performance. Therefore, the higher the quality is typically associated with, the better the additives and the better the engine in response to these additives. That aside, the concept is one that is often misunderstood as there are a number of different octane ratings (e.g. Sinclair Has been in business since 19, not 16, and it's also ranked as one of the top gas stations in the nation. For instance, the high-compression engines in sports cars. To estimate GHG emissions from changing land use, GREET combines land use change modelling results from Purdues Global Trade Analysis Project (GTAP) model with soil organic carbon data and carbon emissions from land use. According to the AAA, "premium gasoline did not result in higher horsepower, better fuel economy, or fewer tailpipe emissions for other vehicles.". Our process is very straightforward and doesn't take more than a couple of days to get your car removed safely and for the most money. Fuels with high octane tend to have more resistance to auto-ignition, hence more time for fuel-air mixing. ). What does octane rating for car fuel mean? No emissions are offset when these petroleum products are burned. High-Octane Fuels automotive and aviation gasolines used in carburetor-type internal-combustion engines with supercharging and a high compression ratio. Even though this isnt true, at least youve heard of high-octane fuel. To increase the total volume of ethanol used to more than 10 percent by volume of the fuel supply (this threshold is commonly referred to as the blend wall), investments in gasoline infrastructure and compatible vehicles are needed to integrate higher blends (e.g. While following the right octane level as recommended in your manual is extremely important, sometimes your vehicle might have significant issues that choosing the right fuel might not make a difference. And make the engine run more smoothly because higher octane ratings are always preferable. The rule of thumb here is to use nothing lower than what your vehicles owner manual tells you to. When all the other kids would break downhill I would pedal harder just to go faster and enjoy the thrill. These cars can use blends of up to 85 percent ethanol. I was just 14 years old at the time and got to ride as a pillion with an older acquaintance. Compression often creates immense heat, and fuels have to withstand tremendous heat; otherwise, it can result in a premature misfire. proximity to an ethanol refinery), and environmental benefits. Costs for equipment needed to utilize blends between E15 and E25 was moderate compared to higher blends. However, there are many myths that people have been following for a long time and never pay attention that they're inaccurate. our vision of a sustainable, resilient, and equitable world. You should check your owners manual for advice or consult a dealer to see how much ping is acceptable for your car, especially when it gets older. It will just waste money. Low calorific value, almost half of that of gasoline. GREET also incorporates updated production improvements at bio-refineries, including increased co-products, reductions in energy and water use, and increased yieldsboth at bio-refineries and in fields. Lets say your manufacturer recommends you use 93 and fill it up with 87; now, youll have a problem. Congress mandated lifecycle greenhouse gas reduction targets for renewable fuels and instructed EPA to oversee this process. Copyright Environmental and Energy Study Institute (EESI). In 2014, the United States produced 14.34 billion gallons of ethanol; ethanol blending in the United States is governed by the Renewable Fuel Standard (RFS). So, it is best to stick to premium gas for premium users. Even while the cleaner fuels typically only cost three cents more per gallon than the dirtier ones, sadly, almost half of us purchase petrol that does not include enough detergent to minimize the filth. This data shows the gains from high octane. And if your vehicle is designed to run on high octane or premium fuel, including many sports cars, you can lose fuel efficiency by switching to a lower rated fuel. This one short ride influenced my every decision in terms of the bikes I want to own. According to research from NREL, the majority of underground storage tanks are able to store blends up to E85, but retailers must demonstrate that their tanks are compatible and decide what storage tanks to devote to which fuels. Even though you might have heard many myths about the advantages of using high octane fuel, some are false. An engine's combustion chamber fills up with deposits more and more as it ages. Use a higher-octane, slower-burning gas to get rid of that engine knock. While mid-level blends were outside the scope of NRELs geographical market analysis, they are the focus of an upcoming analysis. The action of air-fuel mixture combusting spontaneously instead of from the spark plug is known as knocking. Knocking is also the sound it produces in this action. For example, if you did a quick Google search for the octane level. Low-detergent gas might therefore result in increased emissions and decreased fuel efficiency. Researchers from Argonne National Laboratory (ANL), the National Renewable Energy Laboratory (NREL), and Oak Ridge National Lab (ORNL) have been conducting coordinated studies to address the opportunities and challenges of deploying high octane fuels with mid-level ethanol blends to the passenger vehicle fleet. If you love being aware of your impact on the environment, then using a high-octane rating vehicle is a good call. Lower-octane fuel will result in knocking and prevent your vehicle from meeting its stated fuel economy. DOE High-Octane Fuels Study: How much fuel economy can be gained by increasing octane ratings, and how does this answer change for different high-octane blends? All these statements could sound like a mumble jumble, and thats why well explain them more in-depth. In the United States, the majority of ethanol is used as part of the standard E10 blend. Additionally, these states have more refueling infrastructure, spurred on by robust state incentives. Modern cars have an inbuilt engine computer that will prevent knock and engine damage in the long run. For gasoline-powered cars to work, air and fuel mix at carefully timed intervals with a spark plug to bring about ignition. Using higher blends of ethanol as a high octane fuel can achieve significant CO2 reductions in the near-term, helping the United States meet multiple policy objectives. Various engines have varying compression ratios. Theyve probably suggested you do so because it will increase your cars performance, speed, and other aspects. It also does not remove any deposits or clean the engine. As of today Im 26 years old and a proud owner of a Yamaha Fz15 version 2.0 and a Kawasaki Ninja 650 2014 model having clocked a decent 30k Kms only while touring, waiting to clock 1000s more as riding makes me feel whole again after enduring the dismal routines of life. My need for speed began at a very early age and I realised this as soon as I got my first bicycle at the age of 8. The higher the octane number, better the anti-knocking properties (knocking is the phenomena in which the fuel pre-ignites and starts to burn before its ignition time i.e. Emissions The carbon dioxide released by a vehicle when ethanol is burned is offset by the carbon dioxide captured when the feedstock crops are grown to produce ethanol. If pending legislation (S. 1239 and H.R. You will only need to switch up to a higher octane gas if your car starts knocking (which is quite rare), and youve been using the recommended fuel. This is obviously undesirable. During the carburetor's heyday, engine knock was a significant issue. When your engine knocks, it could often result in serious car problems that cost you thousands of dollars. So to burn higher octane numbered fuel you will need an engine with high compression ratio. The strongest E85 markets are in the Midwest, due to their proximity to feedstock growth and ethanol refining facilities. They found an increase in performance when ethanol content was increased from E10 to E30 for three out of four FFVs tested. Instead, you need to follow what's recommended in your vehicle's owners manual and get an idea about what exactly is required. This means that higher octane gas doesnt change the energy content of a gallon of gasoline. The combustion of alcohol gives more moles of exhaust gas, which results in more pressure and power in the expansion stroke. This gas station utilized a specific recipe of additives to improve the engine's performance, optimize fuel economy, lower the annual maintenance costs, and prevent engine deposits.

The following article is from The Great Soviet Encyclopedia (1979). The reason why this myth exists: Octane number is a measure of anti-knocking properties of fuel (Petrol). Now let's see what are the disadvantages of high octane fuel. Some drivers might find it a bit overwhelming to read through the manual. But sports cars engines have that, so a premium grade fuel is better for them. Naturally, the first thing that came into mind was that the higher the number, the higher the quality. There are a lot of products that fall under the fuel additive umbrella, but, for the most part, a fuel additive is something that is added to an engine in order to make its fuel in some way more effective or efficient. Vehicles manufactured using high-octane fuel have lower emissions than those of lower octane vehicles. At least you are aware of high-octane fuel, even though this is untrue. As the octane number increases the compression ratio it can withstand before ignition increases too. Like any other fuel, high octane fuel has its advantages and disadvantages, which we will discuss further in the article. According to recent statistics, buying gasoline from Costco should cost you at least $0.21 per gallon less than the other gas stations. The octane rating varies from car to car. Unfortunately, many people might fall for this issue by investing more in purchasing premium fuel. Combining premium fuel and advanced engine technology becomes a win-win for the manufacturer and the consumer. Thank you. Any other disadvantages? There are many fuel types, including ordinary, premium, and, that you may notice at the petrol station. If your engine has some issues with rattling or knocking or what's known as mistiming combustion, then switching to higher octane level might be one of the common recommendations by most experienced mechanics. A higher octane gas allows your engine to have a higher compression ratio. The primary sources of octane are petroleum refinery products, and ethanol. Conventional ethanol must reduce GHGs by 20 percent, and cellulosic ethanol must reduce GHGs by 60 percent. At ORNL, researchers are investigating the benefits of ethanol as a renewable octane provider. Additionally, the introduction of this high octane mid-level ethanol fuel could provide an optimized fuel source for the much more efficient internal combustion engines carmakers are developing. There could be some harm or none, depending on your cars octane rating. However, you should know that there is the lowest, middle, and highest-octane rating in every gas station. You don't want to go lower or higher than what's asked by your manual. If your vehicle owners manual requests using the highest-octane level, choosing a premium fuel will definitely make a big difference and the way your engine performs. To use higher blends of ethanol, both underground storage tanks and above ground infrastructure compatibility must be assessed at retail gas stations. I was just 14 years old at the time and got to ride as a pillion with an older acquaintance. When looking to fill up your car, you will notice that the change adds to a significant amount. While it might sound that the higher-octane level, the better it is for your vehicle, it might be the total opposite. The cost of manufacturer-approved equipment capable of dealing with E26 to E85 blends is viewed as a serious impediment to greater market penetration of mid-level blends. If the octane is too low, the fuel will burn too fast and too hot which causes detonation and leads to sure-fire engine damage. If you think your vehicle will have more benefit from higher-octane gas, you should know that technically, lower-octane gas has more energy compared to high-octane gas. Currently, high-octane fuel is marketed as 'premium,' but future combustion engines may require higher octane fuels to reach even greater engine efficiencies and higher mile-per-gallon ratings. This means that manufacturers of these vehicles will get charged fewer taxes. EESI advances science-based solutions for climate change, In other words, you must follow with specified in your vehicle's owners manual and never go higher in the octane level, hoping for improving your vehicle's performance. With higher octane gas, your car will have a more advanced ignition timing or forced air inductions. Lets say you fill up your car with the wrong fuel and wonder what harm youve done.
