Does premium gas make your car run better?
Using premium gas in a regular car will cost you more with almost no added benefits. The Federal Trade Commission says that using a high-octane gasoline rather than a recommended one will offer almost no benefits. It will not make your engine perform better or faster.
Does using premium gas increase your mpg?
Other premium additives, however, have the reverse effect, and slightly increase your MPG. So okay, overall premium provides a very slight net increase in MPG, but it's so slight that we swear you won't notice the difference.
Will premium gas harm an engine that can take regular?
With regular gas, fuel economy and acceleration will likely deteriorate at least slightly. Because regular has lower octane, it is more prone to detonation. Burning regular in an engine designed for premium on a long-term basis or under heavy loads can cause engine knock, and that in turn can damage the pistons, valves or spark plugs.
Do you get better gas mileage with premium gasoline?
Premium gas gives you more miles per gallon than regular gas. Premium has special or extra detergents in it that are worth the added cost. I will void my warranty if my owner's manual calls for premium and I use regular unleaded. Using regular gas in a car designed for premium will definitely damage the engine.

Does premium gas last longer than regular gas?
No, premium gas does not last longer than regular gasoline in a fuel tank. A car owner might only consider the longevity of a car's gas if the vehicle has been sitting unused for an extended period.
Does premium gas run longer?
Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbochargers or high-compression engines, so you can hit that horsepower smoothly. Additionally, premium gas can increase fuel efficiency, potentially bringing better gas mileage for longer while decreasing emissions.
What gas burns faster 87 or 93?
Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. In engines designed for standard unleaded fuel, efficiency and performance is optimized for 87 octane and could actually perform worse with higher-octane fuel since the burn rate is slower.
Is there a downside to using premium gas?
Con: Premium gas can be much more expensive. Because of premium gas benefits, this fuel is typically far more expensive than standard gas which, for the average American, can be a pain-point.
What gas gives the best mileage?
premium gasPremium gives better gas mileage Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
Can I mix premium and regular gas?
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
What happens if you put 93 instead of 87?
Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.
Does 93 octane improve gas mileage?
In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.
What's the point of premium gas?
Premium gas, as opposed to regular, is a higher grade of fuel. It's meant for high-performance vehicles and can cost as much as 50 cents more a gallon. Gas that meets Top Tier standards, on the other hand, has higher levels of engine-cleaning additives than non-Top Tier gas.
Is premium gas really worth it?
In a consumer notice, the Federal Trade Commission, notes: “In most cases, using a higher-octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner.”
How much does Premium gas improve mileage?
“If you're using premium fuel in a car that recommends premium, our research found that it could improve horsepower and fuel economy, but only by about three percent. That's a very small difference,” he told VERIFY.
Is buying premium gas a waste of money?
There's also a persistent myth that an occasional tank of premium gas will clean out deposits in your car's engine, but that's not true either. Premium gas won't cause any damage to your car, but its downside is obvious: it costs more money, typically 20 cents per gallon.
Does premium gas burn faster?
Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
How much does Premium gas improve mileage?
“If you're using premium fuel in a car that recommends premium, our research found that it could improve horsepower and fuel economy, but only by about three percent. That's a very small difference,” he told VERIFY.
Which gas lasts the longest?
93 octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel.
Does premium gas make your car go faster?
The higher octane of premium gas won't make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel. It's the fuel's ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
High octane fuel burns slower? - Don Terrill’s Speed-Talk
I'm talking about pump gas not race gas. Hear it all the time,93 burns slower than 87 to resist detonation. I been looking around for real info on this and only found a few things.
Does regular gas burn faster than premium gas? (Perfect answer)
Engine Suitability: Regular unleaded gas burns faster than premium gas, which is why it works better with engines that have low compression ratios.If your vehicle’s engine has a high compression ratio, it is best to use premium gasoline. Although they are both combustible substances, regular unleaded gas actually burns faster than premium gas. This is suitable for engines with low ...
What is the difference between premium gas and regular gas?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time. On occasion, this occurrence will likely not harm your vehicle. However, if it happens frequently it may quicken the decline of your engine's performance.
What happens when you use a lower grade of fuel?
When you use a lower grade of fuel than what’s recommended or required, a modern vehicle’s ECU (Electronic Control Unit) can account for different octane levels and adjust accordingly. There’s a good chance your horsepower and MPG will go down while CO2 emissions go up.
Why do engines use higher octane?
Engines with a high compression ratio typically require higher octane fuel to achieve its intended level of performance, fuel efficiency and emissions. If your car requires premium gas, don’t skimp out. While you might save money on gas, your car will be less powerful and fuel-efficient.
Do you need premium gas for a car?
If your car requires premium gas, don’t skimp out. While you might save money on gas, your car will be less powerful and fuel-efficient.
Can you run a car on premium gas?
But if your owner’s manual says “premium fuel recommended,” you can safely run on regular.
Can you knock a car on low octane?
While older vehicles may be susceptible to engine knock when running on low octane fuel, modern ones are equipped with sensors to help prevent knock—and by extension, engine damage. Your car will probably be fine running on regular once in a while, but we don’t suggest putting it to the test on a regular basis.
Does high compression ratio affect fuel efficiency?
However, if it happens frequently it may quicken the decline of your engine's performance. Engines with high compression ratios or turbochargers often require high octane fuel found in premium gas for optimal performance and fuel efficiency.
How much more is premium gasoline than regular gasoline?
It can be as much as 60 cents more than regular gasoline.
When Should I Use Premium Gas?
While most people probably do not need to use premium gas, there are some who should. Understanding how octane levels work can help you decide whether high-octane fuel is a good idea for your car. However, there are also times when it is a requirement and should be taken seriously.
What is Octane or an Octane Rating?
Essentially, octane is a unit of measurement that dictates how much compression fuel can stand before it ignites. This is why engines with higher compression ratios usually need higher octane levels for their fuel.
What is the myth about premium unleaded gas?
Here are some of the myths and misconceptions about premium unleaded gasoline and why they're easily debunked in some cases: Myth 1: Premium gas increases your MPG. This notion is only likely to be the case if your car really requires premium gas.
Why do cars need premium fuel?
Why Do Some Cars Need Premium Fuel? Premium gas has higher octane rating, which allows some engines to gain more energy from using it. Cars with engines that have higher compression ratios and those with supercharged or turbocharged engines draw more air during regular operation.
How to improve fuel economy?
Better ways to improve your fuel economy, according to the FTC, include keeping your engine tuned and tires properly aligned and inflated. Change your oil as necessary, don't speed, and avoid unnecessary idling in traffic. Myth 2: Premium gas has extra additives or detergents. That stems from confusion between premium gas, ...
What happens when a piston knocks?
Here's what's happening while the knocking is going on: As the piston moves up in the chamber to compress the air and fuel mixture, it receives pressure from properly ignited fuel, which causes it to descend very quickly, which then causes the crankshaft to turn.
Why is octane associated with performance?
Quoted for truth. Octane is associated with performance because high performance engines have designs that require higher octane. Turbocharging, supercharging, high compression are all reasons that an engine has more performance, ...
Why do engines need high octane?
Turbocharging, supercharging, high compression are all reasons that an engine has more performance, they are also reasons they need high octane so they don't have pre-ignition. Pre-ignition can rattle an engine apart and/or burn holes in places they shouldnt be. Last edited by a moderator: Mar 21, 2010. R.
Does octane burn hotter?
Octane rating does not relate to the energy content of the fuel. It doesn't burn any hotter.
Does premium burn slower?
This is a mistake many people think - just because it is less prone to pre-ignite, through additives, does NOT mean it burns slower. Once ignited, Premium burns at basically the same rate as Regular.
Can reg be burned up?
Reg may be burned up before the piston is all the way in it's downstroke and a "ping" or "knock" is the result. Any difference in the temp of the burn would be insignificant I have owned 2 cars that called for Premium, and I always ran regular or mid-grade.
Is BTU the same as explosion?
The btu content is the same. It is a "flash", not an explosion. A nice little envelope of expanding flame front.
Does ethanol increase octane?
By and large,NO. ANY substance added to the gas that helps prevent, or delays preignition with give the Gasoline a higher octane rating. For may years a type of Lead compound was used, Methanol and Ethanol will also serve to raise the octane rating. But they will not cause the fuel to burn hotter.
Why use extra detergents in premium?
The only reason you might have a use for the extra detergents in premium, is if you have a noticeably dirty engine, and need to scrub carbon and other crud off engine components. (And, if you're doing that, we'd instead suggest that you toss in one of the many fine engine additives.) You said "major gas companies.".
How many ingredients are in a gallon of gas?
Each gallon of gas that we pump from our local Quickie Mart is actually made up from as many as seven different ingredients. The exact amount of energy in each gallon of premium or regular gas will vary from company to company, depending upon what kind of additives they use.
Why were auto manufacturers ticked off?
There is. A number of years ago, some of the major auto manufacturers were ticked off with the deposits from gas that met EPA detergent standards. In other words, they were afraid they'd take the heat for problems, when their customer's engines clogged up from the twigs and dirt that was getting deposited on their fine handiwork.
Can you use regular unleaded oil on a modern engine?
We don't believe that any modern engine that claims to require premium will be damaged by using regular unleaded judiciously. Neither do any of the sources we've checked with - including the American Petroleum Institute, the American Engine Rebuilders Association - even a chemist (who would rather go unnamed) at a major gasoline company.
Does premium gas have detergents?
Premium has special or extra detergents in it that are worth the added cost. It's true that premium gas does contain special or extra detergents, but in our opinion they're of no additional benefit. Our advice is to ignore any sales pitch about the super-special detergents that come in the premium-grade fuel.
Does ethanol increase octane?
Finally, here's a nice irony: to increase gas' octane rating, companies add ethanol, when they're mixing up a batch of premium fuel. Interestingly, ethanol actually contains less energy than untreated gas, so the net result from the ethanol component is a reduction in your MPG.
Do you get a greater range of fuel economy between different brands of gas?
In actual fact, you'll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer's regular and premium gasses. Interesting, eh? We thought so.
Why does a high compression engine burn faster?
Any time you compress a gas or air/fuel mixture, you create heat. A high compression engine creates more heat during the compression stroke than a lower compression engine. Some people think that the extra heat in a high compression engine causes regular gas to ignite too early (before the spark plug fires). They also think that it burns faster than premium gas.
How does 87 octane fuel work?
But now that 87-octane fuel experiences a second and much larger rise in pressure which creates far more heat than could be created by the compression stroke alone.
What is an octane?
A fuel’s octane rating is a numerical index of the fuel’s ability to resist detonation. It is not an indication of power. Generally speaking, a higher octane fuel doesn’t contain any more power or detergent.
What is pre-ignition?
Preignition is caused by hot carbon deposits in the engine that ignite the air/fuel mixture before the spark plug fires. The result is the same as detonation–it causes multiple flame fronts; one from the hot carbon and one from the spark plug. That’s why it’s often confused with detonation.
What causes a flame to self ignite?
The rapid rise in temperature due to the added pressure causes multiple flame fronts to ignite across the combustion chamber. When those multiple flame fronts collide, they create audible shock waves known as detonation or “knock”.
What is the term for a condition where hot carbon deposits in the combustion chamber ignite the air/fuel mixture before the?
What these “experts” are describing is actually PRE-IGNITION; a condition where hot carbon deposits in the combustion chamber ignite the air/fuel mixture before the spark plug fires. Pre-ignition can happen in any engine with carbon buildup; it isn’t limited to high compression engines.
How to burn up leaves faster?
Take two piles of leaves and spread them on your driveway. Light one pile multiple places and the other pile in just one place. The pile with multiple fires will burn up faster than the pile with just one ignition point. What does that prove? Only that multiple ignition points will burn up the leaves faster than one ignition point.
