Does premium gas take longer to burn?

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.

Does lower grade 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.

Does 93 octane burn hotter than 87?

Every engine has an “octane rating,” meaning that its basic design requires gasoline that has a certain octane. ... If an engine is rated for regular, which is typically 87 octane in unleaded gas, then that fuel should provide all the necessary protection for the engine. Higher-octane fuel does not burn hotter.

Is it bad to use different grades of gas?

Mixing premium and regular gas is not generally recommended, but doing so will have minimal impact on a vehicle's immediate performance. Only premium cars that require higher octane gasoline may see a minor performance decrease or engine knocking.

What gas last 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. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.

Does cheap gas hurt your car?

You can stop worrying about using cheap gas. Many experts say it's unlikely to hurt your car. ... Additives can also raise the price of the gas. "If you buy gas from Bob's Bargain Basement gas station because that's all that's available, it won't hurt your car," says John Nielsen, AAA's director of engineering and repair.

Does premium gasoline make a difference?

The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. ... Premium gas is not “stronger” gas.

Does premium gas last longer than regular gas?

Sadly, there's nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn't much of a threat on most modern fuel systems.

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.”

What octane is race fuel?

Sunoco® Standard™ is a 110 octane leaded race fuel that is used in many forms of motorsports.

Will higher octane run richer?

Absolutely NOT. Lean is lean. Higher octane only helps with detonation. And you only need a higher octane fuel if you are detonating!

Will premium gas clean my engine?

Nope. Regular, plus, and premium gas all come with detergents to mitigate against carbon deposits in your engine. Plus and premium don't come with special powers for cleaning out the engine. If you're interested in cleaning out your engine, you're better off taking it in for service.

What happens if you put 93 instead of 87?

If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don't worry. You're actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.

Can I mix different octane fuel grades?

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.

Is it OK to mix 89 and 93 gas?

No, you will not damage your engine by mixing different octane fuel. It is still fuel. Say you mixed 2 gallons of 87 octane with 2 gallons of 89 octane and 2 gallons of 93 octane.
