Premium gas gives you more miles per gallon than regular 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.
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.
Does higher grade gas last longer?
So is Higher Octane Fuel More Efficient? 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.
In some cases, these types of fuel are indeed better for your car — but for different reasons. 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. It costs about 3 cents more a gallon, according to AAA.
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.
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.
Generally, properly stored gas can last between 3 to 6 months; if you add fuel stabilizers, you can extend its shelf life by a year or so (under optimal conditions, of course). That gas in your car’s tank, however, will more than likely start degrading in about a month.
How long does 87 octane gas last?
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.
What is the benefit of premium gas?
Boost in Fuel Economy For vehicles that have a higher compression ratio, premium gas allows your vehicle to reach its potential in gas mileage. Although premium gas is more expensive, making the switch to regular in a vehicle that requires premium will see a drop in fuel efficiency.
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.
Premium vs. Regular. 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.
What are the pros and cons of premium gas?
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.
Depending on the type of vehicle you own, the requirement to use premium fuel could come from a number of factors. Your vehicle may have a turbocharged engine, which requires higher octane fuels to operate properly, or maybe you opted for a high-performance car with a high strung engine that operates with tight tolerances.
